ANNEX
1. 

((a)) the use of controlled substances as a reference or standard:

— to calibrate equipment which uses controlled substances,
— to monitor emission levels of controlled substances,
— to determine residue levels of controlled substances in goods, plants and commodities;
((b)) the use of controlled substances in laboratory toxicological studies;
((c)) laboratory uses in which the controlled substance is transformed in a chemical reaction like controlled substances used as feedstock;
((d)) the use of methyl bromide inside a laboratory to compare the efficacy of methyl bromide and its alternatives;
((e)) the use of carbon tetrachloride as a solvent for bromination reactions involving N-bromosuccineimide;
((f)) the use of carbon tetrachloride as chain transfer agent in free-radical polymerisation reactions;
((g)) any other laboratory and analytical use for which a technically and economically feasible alternative is not available.

2. 

((a)) refrigeration and air-conditioning equipment used in laboratories, including refrigerated laboratory equipment such as ultra-centrifuges;
((b)) cleaning, reworking, repair, or rebuilding of electronic components or assemblies;
((c)) preservation of publications and archives;
((d)) sterilisation of materials in a laboratory;
((e)) any use in primary or secondary education;
((f)) as components in experimental chemistry kits available to the general public and not intended for use in higher education;
((g)) for cleaning or drying purposes, including the removal of grease from glassware and other equipment;
((h)) for the determination of hydrocarbons, oils and greases in water, soil, air or waste;
((i)) testing of tar in road paving materials;
((j)) forensic finger-printing;
((k)) testing of organic matter in coal;
((l)) as a solvent in the determination of cyanocobalamin (Vitamin B12) and bromine index;
((m)) in methods that use the selective solubility in the controlled substance, including the determination of cascarosides, thyroid extracts, and the formation of picrates;
((n)) to preconcentrate analytes in chromatographic methods (e.g. high performance liquid chromatography (HPLC), gas chromatography (GC) adsorption chromatography), atomic absorption spectroscopy (AAS), inductively coupled plasma spectroscopy (ICP), X-ray fluorescence analysis;
((o)) for the determination of iodine index in fats and oils;
((p)) any other laboratory and analytical use for which a technically and economically feasible alternative is available.
