REGULATION (EC) No 2003/2003 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 13 October 2003 relating to fertilisers (Text with EEA relevance) 
THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,
Having regard to the Treaty establishing the European Community, and in particular Article 95 thereof,
Having regard to the proposal from the Commission,
Having regard to the Opinion of the European Economic and Social Committee,
Acting in accordance with the procedure laid down in Article 251 of the Treaty,
Whereas:

(1) Council Directive 76/116/EEC of 18 December 1975 on the approximation of the laws of the Member States relating to fertilisers, Council Directive 80/876/EEC of 15 July 1980 on the approximation of the laws of the Member States relating to straight ammonium nitrate fertilisers of high nitrogen content, Commission Directive 87/94/EEC of 8 December 1986 on the approximation of the laws of the Member States relating to procedures for the control of characteristics of, limits for and resistance to detonation of straight ammonium nitrate fertilisers of high nitrogen content, and Commission Directive 77/535/EEC of 22 June 1977 on the approximation of the laws of the Member States relating to methods of sampling and analysis for fertilisers, have been substantially amended several times. In accordance with the communication from the Commission to the European Parliament and the Council ‘Simpler legislation for the internal market’ (SLIM) and the Action Plan for the Single Market those Directives should be repealed and replaced by a single legal instrument, in the interests of clarity.

(2) The Community legislation on fertilisers is very technical in its content. A Regulation is therefore the most appropriate legal instrument, as it imposes directly on manufacturers precise requirements to be applied at the same time and in the same manner throughout the Community.

(3) In each Member State fertilisers must display certain technical characteristics laid down by mandatory provisions. These provisions, concerning more particularly the composition and definition types of fertilisers, the designations of these types, their identification and their packaging, differ from one Member State to another. By their disparity they hinder trade within the Community and should therefore be harmonised.

(4) Since the objective of the proposed action, namely to ensure the internal market in fertilisers, cannot be sufficiently achieved by the Member States if there are no common technical criteria and can therefore, by reason of the scale of the action, be better achieved at Community level, the Community may adopt measures in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty. In accordance with the principle of proportionality, as set out in that Article, this Regulation does not go beyond what is necessary in order to achieve this objective.

(5) It is necessary to determine at Community level the designation, definition and composition of certain fertilisers (EC fertilisers).

(6) Community rules on the identification, traceability and labelling of EC fertilisers and on the closure of the packages should also be laid down.

(7) A procedure should be established at Community level to be followed in cases where a Member State deems it necessary to restrict the placing on the market of EC fertilisers.

(8) The production of fertilisers is subject to varying degrees of fluctuation due to manufacturing techniques or basic materials. Sampling and analytical procedures may also contain variations. It is therefore necessary to authorise tolerances on the declared nutrient contents. In the interest of the agricultural user, it is advisable to keep these tolerances within narrow limits.

(9) Official controls on the compliance of EC fertilisers with requirements of this Regulation concerning quality and composition should be carried out by laboratories that are approved by the Member States and notified to the Commission.

(10) Ammonium nitrate is the essential ingredient of a variety of products, some of which are intended for use as fertilisers and others as explosives. It is necessary, having regard to the particular nature of ammonium nitrate fertilisers of high nitrogen content and to the consequent requirements regarding public safety, health and protection of workers, to lay down additional Community rules for EC fertilisers of this type.

(11) Certain of those products could be hazardous and could in certain instances be used for purposes other than those for which they were intended. This could well endanger the security of persons and property. Manufacturers should therefore be obliged to take appropriate steps to avoid such use, and in particular to ensure the traceability of such fertilisers.

(12) In the interest of public safety, it is particularly important to determine at Community level the characteristics and properties distinguishing ammonium nitrate EC fertilisers of high nitrogen content from varieties of ammonium nitrate used in the manufacture of products used as explosives.

(13) Ammonium nitrate EC fertilisers of high nitrogen content should conform to certain characteristics to ensure that they are harmless. Manufacturers should ensure that all high nitrogen content ammonium nitrate fertilisers have passed a test of resistance to detonation before those fertilisers are placed on the market.

(14) It is necessary to establish rules on the methods of the closed thermal cycles even if these methods may not necessarily simulate all conditions arising during transport and storage.

(15) Fertilisers can be contaminated by substances that can potentially pose a risk to human and animal health and the environment. Further to the opinion of the Scientific Committee on Toxicity, Ecotoxicity and the Environment (SCTEE), the Commission intends to address the issue of unintentional cadmium content in mineral fertilisers and will, where appropriate, draw up a proposal for a Regulation, which it intends to present to the European Parliament and the Council. Where appropriate, a similar review will be undertaken for other contaminants.

(16) It is appropriate to establish a procedure, to be observed by any manufacturer or its representative that wishes to include a new type of fertiliser in Annex I in order to use the marking ‘EC fertiliser’.

(17) The measures necessary for the implementation of this Regulation should be adopted in accordance with Council Decision 1999/468/EC of 28 June 1999 laying down the procedures for the exercise of implementing powers conferred on the Commission.

(18) Member States should lay down penalties in respect of infringements of the provisions of this Regulation. They may provide that a manufacturer which infringes Article 27 can be fined an amount equivalent to ten times the market value of the shipment that fails to comply.

(19) Directives 76/116/EEC, 77/535/EEC, 80/876/EEC and 87/94/EEC should be repealed,
HAVE ADOPTED THIS REGULATION:

Compulsory statements
Article 6 

1. Nothing in this Regulation prevents the appropriate authority, in order to satisfy the requirements of Article 9, from using any power the appropriate authority has to  prescribe that the indication of the nitrogen, phosphorus and potassium contents of fertilisers placed on  the market  is to be expressed in the following way:
(a) nitrogen solely in the elemental form (N); and either
(b) phosphorus and potassium solely in the elemental form (P, K); or
(c) phosphorus and potassium solely in the oxide form (P2O5, K2O); or
(d) phosphorus and potassium in both elemental and oxide forms simultaneously.Where the option is chosen to prescribe that the phosphorus and potassium contents be expressed in the form of elements, all references in the Annexes to the oxide form shall be read as being in elemental form and the numerical values shall be converted using the following factors:
(a) phosphorus (P) = phosphorus pentoxide (P2O5) × 0,436;
(b) potassium (K) = potassium oxide (K2O) × 0,830.
2. Nothing in this Regulation prevents the appropriate authority from using any power the appropriate authority has to  prescribe that the calcium, magnesium, sodium and sulphur contents of secondary nutrient fertilisers and, where the conditions of Article 17 are fulfilled, of primary nutrient fertilisers placed on  the market  are to be expressed:
(a) in the oxide form (CaO, MgO, Na2O, SO3); or
(b) in the elemental form (Ca, Mg, Na, S); or
(c) in both of these forms.To convert the calcium oxide, magnesium oxide, sodium oxide and sulphur trioxide contents into calcium, magnesium, sodium and sulphur contents, the following factors shall be used:

(c) sodium (Na) = sodium oxide (Na2O) × 0,742;
(d) sulphur (S) = sulphur trioxide (SO3) × 0,400.For the calculated oxide or elemental content, the figure declared shall be rounded to the nearest decimal place.
3. The appropriate authority  shall not prevent the placing on the market of an ‘UK fertiliser’ labelled in both of the forms mentioned in paragraphs 1 and 2.
4. The content of one or more of the micro-nutrients boron, cobalt, copper, iron, manganese, molybdenum, or zinc in the  UK fertilisers  belonging to the types of fertilisers listed in sections A, B, C and D of Annex I shall be declared where the following conditions are fulfilled:
(a) the micro-nutrients are added at least in the minimum quantities specified in section E.2.2 and E.2.3 of Annex I;
(b) the  UK fertiliser  continues to satisfy the requirements of sections A, B, C and D of Annex I.
5. Where the micro-nutrients are the normal ingredients of the raw materials intended to supply primary (N, P, K) and secondary (Ca, Mg, Na, S) nutrients, they may be declared, provided that these micro-nutrients are present at least in the minimum quantities specified in sections E.2.2 and E.2.3 of Annex I.
6. The micro-nutrient content shall be declared in the following manner:
(a) for fertilisers belonging to the types of fertilisers listed in section E.1 of Annex I, in accordance with the requirements set out in column 6 of that section;
(b) for mixtures of fertilisers referred to in (a) containing at least two different micro-nutrients and meeting the requirements of section E.2.1 of Annex I and for fertilisers belonging to the types of fertilisers listed in sections A, B, C and D of Annex I, by indicating:
((i)) the total content, expressed as a percentage of the fertiliser by mass,
((ii)) the water-soluble content, expressed as a percentage of the fertiliser by mass, where the soluble content is at least half of the total content.Where a micro-nutrient is totally water-soluble, only the water-soluble content shall be declared.Where a micro-nutrient is chemically linked with an organic molecule, the content of the micro-nutrient present in the fertiliser shall be declared immediately following the water-soluble content as a percentage by mass of the product, followed by one of the terms ‘chelated by’, or ‘complexed by’, with the name of the organic molecule as set out in section E.3 of Annex I. The name of the organic molecule may be replaced by its initials.

((c)) under normal conditions of use it does not adversely affect human, animal, or plant health, or the environment.
Safeguard clause
Article 15 

1. Where  the appropriate authority  has justifiable grounds for believing that a specific  UK fertiliser, although satisfying the requirements of this Regulation, constitutes a risk to safety or health of humans, animals or plants or a risk to the environment,  nothing in this Regulation prevents the appropriate authority from using any power the appropriate authority has to  temporarily prohibit the placing on the market of that fertiliser in its territory or make it subject to special conditions.  Except in the case of a decision in respect of ammonium nitrate fertilisers of high nitrogen content where the decision is outside devolved competence, the appropriate authority shall immediately inform the other appropriate authorities, giving the reasons for the decision.
2. The Secretary of State may, by regulations, in relation to a fertiliser which has been temporarily prohibited from the market under paragraph 1:
(a) amend Annex 1 to impose special conditions in relation to the fertiliser, or
(b) remove the fertiliser from Annex 1.
(2A.) Regulations under paragraph 2 must be made as soon as reasonably practicable—
(a) after the date of receipt of the information referred to in paragraph 1, or
(b) where there is no such information, after the date on which the temporary prohibition begins or special conditions are imposed, as the case may be.
(2B.) Except in the case of a decision in respect of ammonium nitrate fertilisers of high nitrogen content where the decision is outside devolved competence, if a decision is made not to make regulations under paragraph 2, the Secretary of State must immediately inform the other appropriate authorities. After the date of a decision not to make regulations under paragraph 2, the prohibition or special conditions imposed under paragraph 1 no longer have effect.
3. The provisions of this Regulation shall not preclude the taking of measures by the  appropriate authority  which are justified on grounds of public security to prohibit, restrict or hinder the placing on the market of  UK fertilisers.

CONFORMITY ASSESSMENT OF FERTILISERS
Control measures
Article 29 

1. Nothing in this Regulation prevents the appropriate authority from using any power the appropriate authority has to  subject fertilisers marked ‘UK fertiliser’ to official control measures for the purpose of verifying that they comply with this Regulation.Nothing in this Regulation prevents the appropriate authority from using any power the appropriate authority has to  charge fees not exceeding the cost of tests needed for such control measures, but this shall not oblige manufacturers to repeat tests or to pay for repeated tests where the first test was made by a laboratory which fulfilled the conditions of Article 30 and where the test showed compliance of the fertiliser in question.
2. The enforcement authority  shall ensure that sampling and analysis for official controls of  UK fertilisers  belonging to types of fertilisers listed in Annex I are carried out in accordance with the methods described in Annex III and IV.
3. Compliance with this Regulation in respect of conformity to types of fertiliser and compliance with the declared nutrient content and/or the declared content expressed as forms and solubilities of such nutrients may be verified at official inspections only by means of sampling and analysis methods established in accordance with Annex III and IV and taking into account the tolerances specified in Annex II.
4. The  Secretary of State may, by regulations,  adapt and modernise the measuring, sampling and analysis methods and shall, wherever possible, use  recognised standards. ... The  Secretary of State may, by regulations,  specify the control measures provided for in this Article and in Articles 8, 26 and 27.  Regulations  shall in particular address the question of the frequency with which tests need to be repeated, as well as measures that are designed to ensure that the fertiliser put on the market is identical with the fertiliser tested.

ANNEX III TECHNICAL PROVISIONS FOR AMMONIUM NITRATE FERTILISERS OF HIGH NITROGEN CONTENT 
1. Characteristics of and limits for straight ammonium nitrate fertilisers of high nitrogen content 
 1.1. Porosity (oil retention) 

The oil retention of the fertiliser, which must first have undergone two thermal cycles of a temperature ranging from 25 to 50 °C and conforming with the provisions of part 2 of section 3. of this Annex, must not exceed 4 % by mass.
 1.2. Combustible ingredients 

The percentage by mass of combustible material measured as carbon must not exceed 0,2 % for fertilisers having a nitrogen content of at least 31,5 % by mass and must not exceed 0,4 % for fertilisers having a nitrogen content of at least 28 % but less than 31,5 % by mass.
 1.3. pH 

A solution of 10 g of fertiliser in 100 ml of water must have a pH of at least 4.5.
 1.4. Particle size analysis

No limits are specified for other heavy metals.

2. Description of the test of resistance to detonation concerning ammonium nitrate fertilisers of high nitrogen content 

The test must be carried out on a representative sample of fertiliser. Before being tested for resistance to detonation, the whole mass of the sample is to be thermally cycled five times complying with the provisions of part 3 in section 3. of this Annex.

The fertiliser must be subjected to the test of resistance to detonation in a horizontal steel tube under the following conditions:


— seamless steel tube,
— Tube length: 1 000 mm at least,
— Nominal external diameter: 114 mm at least,
— Nominal wall thickness: 5 mm at least,
— Booster: the type and mass of the booster chosen should be such as to maximise the detonation pressure applied to the sample in order to determine its susceptibility to the transmission of detonation,
— Test temperature: 15-25 °C,
— Witness lead cylinders for detecting detonation: 50 mm diameter and 100 mm high
— placed at 150 mm intervals and supporting the tube horizontally. The test is to be carried out twice. The test is deemed conclusive if in both tests one or more of the supporting lead cylinders is crushed by less than 5 %.

3. Methods of checking compliance with the limits specified in Annexes III-1 and III-2 
 Method 1 Methods for the application of thermal cycles 
 1. Scope and field of application 

This document defines the procedures for the application of thermal cycles prior to the execution of the oil retention test for straight ammonium nitrate fertilisers of high nitrogen content and of the test on the resistance to detonation for both, straight and compound ammonium nitrate fertiliser of high nitrogen content.

The methods of the closed thermal cycles as described in this section are regarded as simulating sufficiently the conditions to be taken into account within the scope of application of title II, chapter IV, however, these methods may not necessarily simulate all conditions arising during transport and storage;
 2. Thermal cycles referred to in Annex III-1 
 2.1. Field of application 

This procedure is for thermal cycling prior to determining the oil retention of the fertiliser.
 2.2. Principle and definition 

In an Erlenmeyer flask, heat the sample from ambient temperature to 50 °C and maintain at this temperature for a period of two hours (phase at 50 °C). Thereupon cool the sample until a temperature of 25 °C is achieved and maintain at that temperature for two hours (phase at 25 °C). The combination of the successive phases at 50 °C and 25 °C forms one thermal cycle. After being subjected to two thermal cycles, the test sample is held at a temperature of 20 ± 3 °C for the determination of the oil retention value.
 2.3. Apparatus 

Normal laboratory apparatus, in particular:


— water baths thermostated at 25 (± 1) and 50 (± 1) °C respectively,
— Erlenmeyer flasks with an individual capacity of 150 ml.
 2.4. Procedure 

Put each test sample of 70 (± 5) grams into an Erlenmeyer flask which is then sealed with a stopper.

Move each flask every two hours from the 50 °C bath to the 25 °C bath and vice versa.

Maintain the water in each bath at constant temperature and keep in motion by rapid stirring to ensure the water level comes above the level of the sample. Protect the stopper from condensation by a foam rubber cap.
 3. Thermal cycles to be used for Annex III-2 
 3.1. Field of application 

This procedure is for thermal cycling prior to the execution of the detonability test.
 3.2. Principle and definition 

In a watertight box heat the sample from ambient temperature to 50 °C and maintain at this temperature for a period of one hour (phase at 50 °C). Thereupon cool the sample until a temperature of 25 °C is achieved and maintain at that temperature for one hour (phase at 25 °C). The combination of the successive phases at 50 °C and 25 °C forms one thermal cycle. After being subjected to the required number of thermal cycles, the test sample is held at a temperature of 20 ± 3 °C pending the execution of the detonability test.
 3.3. Apparatus 


— A water bath, thermostated in a temperature range of 20 to 51 °C with a minimum heating and cooling rate of 10 °C/h, or two water baths, one thermostated at a temperature of 20 °C, the other at 51 °C. The water in the bath(s) is continuously stirred; the volume of the bath should be large enough to guarantee ample circulation of the water.
— A stainless steel box, watertight all around and provided with a thermocouple in the centre. The outside width of the box is 45 (± 2) mm and the wall thickness is 1,5 mm (see Figure 1). The height and length of the box can be chosen to suit the dimensions of the water bath, e.g. length 600 mm, height 400 mm.
 3.4. Procedure 

Place a quantity of fertilisers sufficient for a single detonation into the box and close the cover. Place the box in the water bath. Heat the water to 51 °C and measure the temperature in the centre of the fertiliser. One hour after the temperature at the centre has reached 50 °C cool the water. One hour after the temperature at the centre has reached 25 °C heat the water to start the second cycle. In the case of two water baths, transfer the box to the other bath after each heating/cooling period.

 Method 2 Determination of oil retention 
 1. Scope and field of application 

This document defines the procedure for the determination of oil retention of straight ammonium nitrate fertilisers of high nitrogen content.

The method is applicable to both prilled and granular fertilisers which do not contain oil-soluble materials.
 2. Definition 

Oil retention of a fertiliser: the quantity of oil retained by the fertiliser determined under the operating conditions specified, and expressed as a percentage by mass.
 3. Principle 

Total immersion of the test portion in gas oil for a specified period, followed by the draining away of surplus oil under specified conditions. Measurement of the increase in mass of the test portion.
 4. Reagent 

Gas oil

Viscosity max.5 mPas at 40 °CDensity0,8 to 0,85 g/ml at 20 °CSulphur content≤ 1,0 % (m/m)Ash≤ 0,1 % (m/m)
 5. Apparatus 

Ordinary laboratory apparatus, and:


5.1. Balance, capable of weighing to the nearest 0,01 gram.
5.2. Beakers, of capacity 500 ml.
5.3. Funnel, of plastic materials, preferably with a cylindrical wall at the upper end, diameter approximately 200 mm.
5.4. Test sieve, aperture 0,5 mm, fitting into the funnel (5.3).Note: The size of the funnel and sieve is such as to ensure that only a few granules lie one above another and the oil is able to drain easily.
5.5. Filter paper, rapid filtering grade, creped, soft, mass 150 g/m2.
5.6. Absorbent tissue (laboratory grade).
 6. Procedure 
 6.1. Two individual determinations are carried out in quick succession on separate portions of the same test sample.
 6.2. Remove particles smaller than 0,5 mm using the test sieve (5.4). Weigh to the nearest 0,01 gram approximately 50 grams of the sample into the beaker (5.2). Add sufficient gas oil (section 4) to cover the prills or granules completely and stir carefully to ensure that the surfaces of all the prills or granules are fully wetted. Cover the beaker with a watch glass and leave to stand for one hour at 25 (± 2) °C.
 6.3. Filter the entire contents of the beaker through the funnel (5.3) containing the test sieve (5.4). Allow the portion retained by the sieve to remain there for one hour so that most of the excess oil can drain away.
 6.4. Lay two sheets of filter paper (5.5) (about 500 × 500 mm) on top of each other on a smooth surface; fold the four edges of both filter papers upwards to a width of about 40 mm to prevent the prills from rolling away. Place two layers of absorbent tissue (5.6) in the centre of the filter papers. Pour the entire contents of the sieve (5.4) over the absorbent tissues and spread the prills evenly with a soft, flat brush. After two minutes lift one side of the tissues to transfer the prills to the filter papers beneath and spread them evenly over these with the brush. Lay another sheet of filter paper, similarly with its edges turned upward, on the sample and roll the prills between the filter papers with circular movements while exerting a little pressure. Pause after every eight circular movements to lift the opposite edges of the filter papers and return to the centre the prills that have rolled to the periphery. Keep to the following procedure: make four complete circular movements, first clockwise and then anticlockwise. Then roll the prills back to the centre as described above. This procedure to be carried out three times (24 circular movements, edges lifted twice). Carefully insert a new sheet of filter paper between the bottom sheet and the one above it and allow the prills to roll onto the new sheet by lifting the edges of the upper sheet. Cover the prills with a new sheet of filter paper and repeat the same procedure as described above. Immediately after rolling, pour the prills into a tared dish and reweigh to the nearest 0,01 gram to determine the mass of the quantity of gas oil retained.
 6.5. Repeating the rolling procedure and reweighing 

If the quantity of gas oil retained in the portion is found to be greater than 2 grams, place the portion on a fresh set of filter papers and repeat the rolling procedure, lifting the corners in accordance with section 6.4 (two times eight circular movements, lifting once). Then reweigh the portion.
 7. Expression of the results 
 7.1. Method of calculation and formula 

The oil retention, from each determination (6.1) expressed as a percentage by mass of the sieved test portion, is given by the equation:

Oilretention=m2−m1m1× 100

where:


 m1 is the mass, in grams, of the sieved test portion (6.2),
 m2 is the mass, in grams, of the test portion according to section 6.4 or 6.5 respectively as the result of the last weighing.

Take as the result the arithmetic mean of the two individual determinations.

Assemble the apparatus as indicated in the diagram: connect one end of the absorption tube (A) to the nitrogen source (4.2) via a non-return flow device containing a pressure of 667 to 800 Pa and the other end to the feed tube which enters the reaction flask. Place the Vigreux fractionating column (C′) and the condenser (C) with cooling water supply in position. Adjust the nitrogen to provide a moderate flow through the solution, bring the solution to boiling point and heat for two minutes. At the end of this time there should be no more effervescence. If effervescence is seen, continue heating for 30 minutes. Allow solution to cool for at least 20 minutes with the nitrogen flowing through it.

Complete assembly of the apparatus as indicated in the diagram by connecting the condenser tube to the Drechsel bottle (D) and the bottle to the absorption vessels F1 and F2. The nitrogen must continue to pass through the solution during the assembly operation. Rapidly introduce 50 ml of barium hydroxide solution (3.4) into each of the absorption vessels (F1 and F2).

Bubble a stream of nitrogen through for about 10 minutes. The solution must remain clear in the absorbers. If this does not happen, the carbonate removal process must be repeated.
 5.3. Oxidation and absorption 

After withdrawing the nitrogen feed tube, rapidly introduce 20 grams of chromium trioxide (3.1) and 6 ml of silver nitrate solution (3.3) via the side arm of the reaction flask (B). Connect the apparatus to the suction pump and adjust the nitrogen flow so that a steady stream of gas bubbles passes through the sintered-glass absorbers F1 and F2.

Heat the reaction flask (B) until the liquid boils and keep it boiling for one and a half hours. It may be necessary to adjust the suction-regulating valve (G) to control the nitrogen flow since it is possible that the barium carbonate precipitated during the test may block the sintered-glass discs. The operation is satisfactory when the barium hydroxide solution in the absorber F2 remains clear. Otherwise repeat the test. Stop heating and dismantle the apparatus. Wash each of the distributors (3.10) both inside and outside to remove barium hydroxide and collect the washings in the corresponding absorber. Place the distributors one after the other in a 600-ml beaker which will subsequently be used for the determination.

Rapidly filter under vacuum firstly the contents of absorber F2 and then of absorber F1 using the sintered-glass crucible. Collect the precipitate by rinsing the absorbers with water (3.10) and wash the crucible with 50 ml of the same water. Place the crucible in the 600-ml beaker and add about 100 ml of boiled water (3.10). Introduce 50 ml of boiled water into each of the absorbers and pass nitrogen through the distributors for five minutes. Combine the water with that from the beaker. Repeat the operation once to ensure that the distributors are rinsed thoroughly.
 5.4. Measurement of the carbonates originating from organic material 

Add five drops of phenolphthalein (3.8) to the contents of the beaker. The solution becomes red in colour. Add hydrochloric acid (3.5) drop by drop until the pink colour just disappears. Stir the solution well in the crucible to check that the pink colour does not reappear. Add five drops of bromphenol blue (3.7) and titrate with hydrochloric acid (3.5) until the solution turns yellow. Add a further 10 ml of hydrochloric acid.

Heat the solution to boiling point and continue boiling for a maximum of one minute. Check carefully that no precipitate remains in the liquid.

Allow to cool and back titrate with the sodium hydroxide solution (3.6).
 6. Blank test 

Carry out a blank test following the same procedure and using the same quantities of all reagents.
 7. Expression of the results 

The content of combustible ingredients (C), expressed as carbon, as a percentage by mass of the sample, is given by the formula:

C %=0,06 ×V1−V2E

where:

Ethe mass in grams of the test portion,V1the total volume in ml of 0,1 mol/l hydrochloric acid added after the change in colour of the phenolphthalein,V2the volume in ml of the 0,1 mol/l sodium hydroxide solution used for back titration.

This document defines the procedure for the determination of the chlorine content (as chloride ion) of straight ammonium nitrate fertilisers with a high nitrogen content.
 2. Principle 

Chloride ions dissolved in water are determined by potentiometric titration with silver nitrate in an acidic medium.
 3. Reagents 

Distilled or demineralised water, free from chloride ions.
 3.1. Acetone AR.
 3.2. Concentrated nitric acid (density at 20 °C = 1,40 g/ml)

Weigh, to the nearest 0,1 mg, 3,7276 grams of analytical-grade potassium chloride, previously dried for one hour in an oven at 130 °C and cooled in a desiccator to ambient temperature. Dissolve in a little water, transfer the solution without loss into a 500-ml standard flask, dilute to the mark and mix.
 3.6. Potassium chloride, 0,004 mol/l standard reference solution — prepare this solution at the time of use.

 4.3. Magnetic stirrer, with a Teflon-coated rod.
 4.4. Microburette with fine-pointed tip, graduated in 0,01 ml divisions.
 5. Procedure 
 5.1. Standardisation of the silver nitrate solution 

Take 5,00 ml and 10,00 ml of the standard reference potassium chloride solution (3.6) and place in two low-form beakers of convenient capacity (for example 250 ml). Carry out the following titration of the contents of each beaker.

Add 5 ml of the nitric acid solution (3.2), 120 ml of the acetone (3.1) and sufficient water to bring the total volume to about 150 ml. Place the rod of the magnetic stirrer (4.3) in the beaker and set the stirrer in motion. Immerse the silver electrode (4.1) and the free end of the bridge (4.2) in the solution. Connect the electrodes to the potentiometer (4.1) and, after verifying the zero of the apparatus, note the value of the starting potential.

Titrate, using the microburette (4.4), adding initially 4 or 9 ml respectively of the silver nitrate solution corresponding to the standard reference potassium chloride solution used. Continue the addition in 0,1 ml portions for the 0,004 mol/l solutions and in 0,05 ml portions for the 0,1 mol/l solutions. After each addition, await the stabilisation of the potential.

Record the volumes added and the corresponding values of the potential in the first two columns of a table.

In a third column of the table, record the successive increments (Δ1E) of the potential E. In a fourth column, record the differences (Δ2E) positive or negative, between the potential increments (Δ1E). The end of the titration corresponds to the addition of the 0,1 or 0,05 ml portion (V1) of the silver nitrate solution which gives the maximum value of Δ1E.

In order to calculate the exact volume (Veq) of the silver nitrate solution corresponding to the end of the reaction, use the formula:

Veq=V0+V1×bB

where:


 V0 is the total volume, in ml, of the silver nitrate solution immediately lower than the volume which gives the maximum increment of Δ1E,
 V1 is the volume, in ml, of the last portion of the silver nitrate solution added (0,1 or 0,05 ml),
 b is the last positive value of Δ2E,
 B is the sum of the absolute values of the last positive values of Δ2E and the first negative value of Δ2E (see example in Table 1).
 5.2. Blank test 

Carry out a blank test and take account thereof when calculating the final result.

The result V4 of the blank test on the reagents is given, in ml, by the formula:
V4=2V3−V2
where:


 V2 is the value, in ml, of the exact volume (Veq) of the silver nitrate solution corresponding to the titration of 10 ml of the potassium chloride standard reference solution used,
 V3 is the value, in ml, of the exact volume (Veq) of the silver nitrate solution corresponding to the titration of 5 ml of the potassium chloride standard reference solution used.
 5.3. Check test 

The blank test can at the same time serve as a check that the apparatus is functioning satisfactorily and that the test procedure is being implemented correctly.
 5.4. Determination 

Take a portion of sample in the range 10 to 20 grams and weigh to the nearest 0,01 gram. Transfer quantitatively to a 250-ml beaker. Add 20 ml of water, 5 ml of nitric acid solution (3.2), 120 ml of acetone (3.1) and sufficient water to bring the total volume to about 150 ml.

Place the rod of the magnetic stirrer (4.3) in the beaker, place the beaker on the stirrer and set the stirrer in motion. Immerse the silver electrode (4.1) and the free end of the bridge (4.2) in the solution, connect the electrodes to the potentiometer (4.1) and, after having verified the zero of the apparatus, note the value of the starting potential.

Titrate with the silver nitrate solution, by additions from the microburette (4.4) in increments of 0,1 ml. After each addition, await the stabilisation of the potential.

Continue the titration as specified in 5.1, starting from the fourth paragraph: ‘Record the volumes added and the corresponding values of the potential in the first two columns of a table …’.
 6. Expression of the results 

Express the result of the analysis as the percentage of chlorine contained in the sample as received for analysis. Calculate the percentage of chlorine (Cl) content from the formula:

Cl %=0,3545 × T ×V5−V4×100m

where:


 T is the concentration of silver nitrate solution used, in mol/l
 V4 is the result, in ml, of the blank test (5.2),
 V5 is the value, in ml, of Veq corresponding to the determination (5.4),
 m is the mass, in grams, of the test portion.

Prepare this solution at the time of use.
 4. Apparatus 

Atomic absorption spectrophotometer with a copper lamp (324,8 nm).
 5. Procedure 
 5.1. Preparation of the solution for analysis 

Weigh, to the nearest 0,001 gram, 25 grams of the sample, place it in a 400-ml beaker, add carefully 20 ml of hydrochloric acid (3.1) (there may be a vigorous reaction due to carbon dioxide formation). Add more hydrochloric acid, if necessary. When effervescence has stopped, evaporate to dryness on a steam bath, stirring occasionally with a glass rod. Add 15 ml 6 mol/l hydrochloric acid solution (3.2) and 120 ml of water. Stir with the glass rod, which should be left in the beaker, and cover the beaker with a watch glass. Boil the solution gently until dissolution is complete and then cool.

Transfer the solution quantitatively into a 250-ml graduated flask, by washing the beaker with 5 ml 6 mol/l hydrochloric acid (3.2), and twice with 5 ml of boiling water, make up to the mark with 0,5 mol/l hydrochloric acid (3.3) and mix carefully.

Filter through a copper-free filter paper, discarding the first 50 ml.
 5.2. Blank solution 

Prepare a blank solution from which only the sample has been omitted and allow for this in the calculation of the final results.
 5.3. Determination 
 5.3.1. Preparation of sample and blank test solutions 

Dilute the sample solution (5.1) and the blank test solution (5.2) with 0,5 mol/l hydrochloric acid solution (3.3) to a concentration of copper within the optimal measuring range of the spectrophotometer. Normally no dilution is needed.
 5.3.2. Preparation of the calibration solutions 

By diluting the standard solution (3.6.1) with 0,5 mol/l hydrochloric acid solution (3.3), prepare at least five standard solutions corresponding to the optimal measuring range of the spectrophotometer (0 to 5,0 mg/l Cu). Before making up to the mark, add to every solution ammonium nitrate (3.4) to give concentration of 100 mg per ml.

This document defines the procedure for the determination or resistance to detonation of ammonium nitrate fertilisers of high nitrogen content.
 4.2. Principle

 4.3.12. Dressmaking pins (maximum length 20 mm)
 4.4. Procedure 
 4.4.1. Preparation of booster charge for insertion into steel tube 

There are two methods of initiation of the explosive in the booster charge, depending on the availability of equipment.
 4.4.1.1. Seven-point simultaneous initiation 

The booster charge prepared for use is shown in Figure 1.
 4.4.1.1.1. Drill holes in the wooden disc (4.3.10) parallel to the axis of the disc through the centre and through six points symmetrically distributed around a concentric circle 55 mm in diameter. The diameter of the holes must be 6 to 7 mm (see Section A-B in Figure 1), depending on the diameter of the detonating cord used (4.3.2).
 4.4.1.1.2. Cut seven lengths of flexible detonating cord (4.3.2) each 400 mm long, avoiding any loss of explosive at each end by making a clean cut and immediately sealing the end with adhesive. Push each of the seven lengths through the seven holes in the wooden disc (4.3.10) until their ends project a few centimetres on the other side of the disc. Then insert a small dressmaking pin (4.3.12) transversally into the textile sleeve of each length of cord 5 to 6 mm from the end and apply adhesive around the outside of the lengths of cord in a band 2 cm wide adjacent to the pin. Finally, pull the long piece of each cord to bring the pin into contact with the wooden disc.
 4.4.1.1.3. Shape the plastic explosive (4.3.1) to form a cylinder 92 to 96 mm in diameter, depending on the diameter of the cylinder (4.3.8). Stand this cylinder upright on a level surface and insert the shaped explosive. Then insert the wooden disc carrying the seven lengths of detonating cord into the top of the cylinder and press it down onto the explosive. Adjust the height of the cylinder (64 to 67 mm) so that its top edge does not extend beyond the level of the wood. Finally, fix the cylinder to the wooden disc for instance with staples or small nails, around its entire circumference.
 4.4.1.1.4. Group the free ends of the seven lengths of detonating cord around the circumference of the wooden rod (4.3.11) so that their ends are all level in a plane perpendicular to the rod. Secure them in a bundle around the rod by means of adhesive tape.
 4.4.1.2. Central initiation by a compressed pellet 

The booster charge prepared for use is shown in Figure 2.
 4.4.1.2.1. Preparing a compressed pellet 

Taking the necessary safety precautions, place 10 grams of a secondary explosive (4.3.3) in a mould with an inside diameter of 19 to 21 mm and compress to the correct shape and density.

(The ratio of diameter: height should be roughly 1:1).

In the centre of the bottom of the mould there is a peg, 12 mm in height and 7,0 to 7,3 mm in diameter (depending on the diameter of the detonator used), which forms a cylindrical recess in the compressed cartridge for subsequent insertion of the detonator.
 4.4.1.2.2. Preparing the booster charge 

Place the explosive (4.3.1) into the cylinder (4.3.8) standing upright on a level surface, then press it down with a wooden die to give the explosive a cylindrical shape with a central recess. Insert the compressed pellet into this recess. Cover the cylindrically shaped explosive containing the compressed pellet with a wooden disc (4.3.10) having a central hole 7,0 to 7,3 mm in diameter for insertion of a detonator. Fix the wooden disc and the cylinder together with a cross of adhesive tape. Ensure that the hole drilled in the disc and the recess in the compressed pellet are coaxial by inserting the wooden rod (4.3.11).
 4.4.2. Preparing steel tubes for the detonation tests 

At one end of the steel tube (4.3.4), drill two diametrically opposed holes 4 mm in diameter perpendicularly through the side wall at a distance of 4 mm from the edge.

Butt weld the bottom plate (4.3.5) to the opposite end of the tube, completely filling the right angle between the bottom place and the wall of the tube with weld metal around the entire circumference of the tube.
 4.4.3. Filling and charging the steel tube 

See Figures 1 and 2.
 4.4.3.1. The test sample, the steel tube and the booster charge must be conditioned to temperatures of 20 (± 5) °C. 16 to 18 kg of the test sample are needed for two detonation tests.
 4.4.3.2. Place the tube upright with its square bottom place resting on a firm, flat surface, preferably concrete. Fill the tube to about one-third of its height with the test sample and drop it 10 cm vertically onto the floor five times to compact the prills or granules as densely as possible in the tube. To accelerate compaction, vibrate the tube by striking the side wall with a 750 to 1 000-gram hammer between drops for a total of 10 times. 

Repeat this charging method with another portion of the test sample. Finally, a further addition shall be made such that, after compaction by raising and dropping the tube 10 times and a total of 20 intermittent hammer blows, the charge fills the tube to a distance of 70 mm from its orifice.

The filling height of the sample must be adjusted in the steel tube so that the booster charge (4.4.1.1 or 4.4.1.2) to be inserted later will be in close contact with the sample over its entire surface.
 4.4.3.3. Insert the booster charge into the tube so that it is in contact with the sample; the top surface of the wooden disc must be 6 mm below the end of the tube. Ensure essential close contact between explosive and test sample by adding or removing small quantities of sample. As shown in Figures 1 and 2, split pins should be inserted through the holes near the open end of the tube and their legs opened flat against the tube.
 4.4.4. Positioning of the steel tube and lead cylinders (see figure 3) 
 4.4.4.1. Number the bases of the lead cylinders (4.3.6) 1 to 6. Make six marks 150 mm apart on the centre line of a steel block (4.3.7) lying on a horizontal base, with the first mark at least 75 mm from the edge of the block. Place a lead cylinder upright on each of these marks, with the base of each cylinder centred on its mark.
 4.4.4.2. Lay the steel tube prepared according to 4.4.3 horizontally on the lead cylinders so that the axis of the tube is parallel to the centre line of the steel block and the welded end of the tube extends 50 mm beyond lead cylinder No 6. To prevent the tube from rolling, insert small wooden wedges between the tops of the lead cylinders and the tube wall (one on each side) or place a cross of wood between the tube and the steel block. 
Note: Make sure that the tube is in contact with all six lead cylinders; a slight curvature of the tube surface can be compensated for by rotating the tube about its longitudinal axis; if any of the lead cylinders is too tall, tap the cylinder in question carefully with a hammer until it is the required height. 4.4.5. Preparation for detonation 
 4.4.5.1. Set up the apparatus according to the 4.4.4 in a bunker or suitably prepared underground site (e.g. mine or tunnel). Ensure that the temperature of the steel tube is kept at 20 (± 5) °C before detonation. 
Note: Should such firing sites not be available, the work can, if necessary, be done in a concrete-lined pit covered over with wooden beams. Detonation can cause steel fragments to be projected with high kinetic energy, therefore, firing must be carried out at a suitable distance from dwellings or thoroughfares. 4.4.5.2. If the booster charge with seven-point initiation is used, ensure that the detonation cords are stretched out as described in the footnote to 4.4.1.1.4 and arranged as horizontally as possible.
 4.4.5.3. Finally, remove the wooden rod and replace with the detonator. Do not carry out firing until the danger zone has been evacuated and the test personnel have taken cover.
 4.4.5.4. Detonate the explosive.

ANNEX IV METHODS OF SAMPLING AND ANALYSIS 
A. METHOD OF SAMPLING FOR THE CONTROL OF FERTILISERS 
INTRODUCTION 

Correct sampling is a difficult operation which requires the greatest of care. The need to obtain a sufficiently representative sample for the official testing of fertilisers cannot, therefore, be stressed too much.

The sampling method described below must be applied with strict accuracy by specialists with experience of the conventional sampling procedure.
 1. Purpose and scope 

Samples intended for the official control of fertilisers, for quality and composition, shall be taken according to the methods described below. Samples thus obtained shall be considered as representative of the sampled portions.
 2. Sampling officers 

The samples shall be taken by specialist officers authorised for that purpose by the appropriate authority.
 3. Definitions 

Sampled portionA quantity of product constituting a unit, and having characteristics presumed to be uniform.Incremental sampleA quantity taken from one point in the sampled portion.Aggregate sampleAn aggregate of incremental samples taken from the same sampled portion.Reduced sampleA representative part of the aggregate sample, obtained from the latter by a process of reduction.Final sampleA representative part of the reduced sample.
 4. Apparatus 
 4.1. The sampling apparatus must be made of materials which cannot affect the characteristics of the products to be sampled. Such apparatus may be officially approved by the appropriate authority.

 5.3. Aggregate sample 

A single aggregate sample per sampled portion is required. The total mass of the incremental samples making up the aggregate sample shall be not less than the following:


5.3.1. Loose solid fertilisers or fluid fertilisers in containers exceeding 100 kg: 4 kg.
5.3.2. Packaged solid fertilisers or fluid fertilisers in containers (= packages) each not exceeding 100 kg

 5.4.2.2. Minimum final sample mass for Annex III.2 tests: 25 kg
 6. Instructions for taking, preparing and packaging the samples 
 6.1. General 

The samples must be taken and prepared as quickly as possible bearing in mind the precautions necessary to ensure that they remain representative of the fertiliser sampled. Instruments and also surfaces and containers intended to receive samples must be clean and dry.

In the case of fluid fertilisers, if possible the sampled portion should be mixed prior to sampling.
 6.2. Incremental samples 

Incremental samples must be taken at random throughout the whole sampled portion and they must be of approximately equal sizes.
 6.2.1. Loose solid fertilisers or fluid fertilisers in containers exceeding 100 kg 

An imaginary division shall be made of the sampled portion into a number of approximately equal parts. A number of parts corresponding to the number of incremental samples required in accordance with 5.2 shall be selected at random and at least one sample taken from each of these parts. Where it is not possible to comply with the requirements of 5.1 when sampling bulk fertilisers or fluid fertilisers in containers exceeding 100 kg the sampling should be carried out when the sampled portion is being moved (loading or unloading). In this case samples shall be taken from the randomly selected notional parts as defined above while these are being moved.
 6.2.2. Packaged solid fertilisers or fluid fertilisers in containers (= packages) each not exceeding 100 kg 

Having selected the required number of packages for sampling as indicated in 5.2, part of the contents of each package shall be removed. Where necessary, the samples shall be taken after emptying the packages separately.
 6.3. Preparation of aggregate sample 

The incremental samples shall be mixed to form a single aggregate sample.
 6.4. Preparation of the final sample 

The material in the aggregate sample shall be carefully mixed.

If necessary the aggregate sample should first be reduced to at least 2 kg (reduced sample) either by using a mechanical divider or by the quartering method.

At least three final samples shall then be prepared, of approximately the same amount and conforming to the quantitative requirements of 5.4. Each sample shall be put into an appropriate air tight container. All necessary precautions shall be taken to avoid any change in the characteristics of the sample.

For the tests of Annex III, sections 1 and 2, the final samples shall be kept at a temperature between 0 °C and 25 °C.
 7. Packaging of final samples 

The containers or packages shall be scaled and labelled (the total label must be incorporated in the seal) in such a manner that they cannot be opened without damaging the seal.
 8. Sampling record 

A record must be kept of each sampling, permitting each sampled portion to be identified unambiguously.
 9. Destination of samples 

For each sample portion at least one final sample shall be sent as quickly as possible to an authorised analytical laboratory or to the test institution, together with the information necessary for the analysis or the test.

B. METHODS FOR THE ANALYSIS OF FERTILISERS 
(See table of contents p. 2.)General observations 
Laboratory equipment 

In the descriptions of the methods, general laboratory equipment has not been precisely defined, except that the sizes of flasks and pipettes are given. In all cases laboratory apparatus must be well cleaned, particularly when small quantities of elements are to be determined.
Control tests 

Before analysis it is necessary to ensure that all apparatus functions well and that the analytical technique is carried out correctly, using where appropriate chemical compounds of known composition (e.g. ammonium sulphate, mono potassium phosphate, etc.). Nevertheless, the results from analysed fertilisers can indicate wrong chemical composition if the analytical technique is not rigorously followed. On the other hand, a certain number of determinations are empirical and are relative to products of complex chemical composition. It is recommended that where available, laboratories should make use of standard reference fertilisers of well defined composition.
General provisions relating to methods of analysing fertilisers 
 1. Reagents 

Unless otherwise specified in the method of analysis, all of the reagents must be analysis-pur (a.p.). Where micro-nutrients are to be analysed the purity of the reagents must be checked by means of a blank test. Depending upon the result obtained, it might be necessary to conduct a further purification.
 2. Water 

Where dissolution, dilution, rinsing or washing operations referred to in the methods of analysis do not specify the nature of solvents or diluents the use of water is implied. Normally, the water will have to be demineralised or distilled. In these specific instances, as mentioned in the method of analysis, that water will have to be subjected to specific purification processes.
 3. Laboratory equipment 

In view of the equipment normally used in inspection laboratories, the apparatus described in the methods of analysis is restricted to special instruments and apparatus or to such demanded by any specific requirements. This equipment must be perfectly clean, above all where small quantities are to be determined. The laboratory will have to ensure the accuracy of any graduated glassware used by referring to appropriate metrological standards.
