(1) The tests specified in sub-paragraphs (2), (3) and (4) below shall be carried out on a discontinuous totaliser under normal conditions of use.
(2) A minimum of three individual tests (including at least one at minimum load and at least one at maximum capacity) shall be carried out, each test involving the weighing of a quantity of suitable material as nearly as practicable equal to the minimum totalised load marked on the machine.
(3) In the case only of a discontinuous totaliser first passed as fit for use for trade before 29th April 1996, and if the person submitting it for testing so requests, the test at maximum capacity under sub-paragraph (2) above may be made with twenty separate loads and the words “as nearly as practicable equal to the minimum totalised load marked on the machine” in that sub-paragraph shall not have effect.
(4) Unless already included in the tests carried out under sub-paragraphs (2) and (3) above two further tests (which shall include at least five weighing cycles and a quantity of material not less than the minimum totalised load) shall be carried out, one at the minimum load and one at the maximum capacity.
(5) For each of the tests carried out under sub-paragraphs (2), (3) and (4) above, the inspector shall determine—
(a) the weight of material used in the test using the arrangements referred to in paragraph 5 above;
(b) the material testing error by ascertaining the difference between the weight of the material determined in accordance with sub-paragraph (a) above and the value of the weight of the material obtained from the totalisation indicating device.
PART III
7 
Where a discontinuous totaliser is constructed with an internal non-automatic weighing facility complying with regulations 9 and 24(1)(a) the machine may be tested by the use of that facility if the facility has first been tested by standard weights to verify that the weight indicating device (if necessary, in conjunction with a calibration chart or graph prepared from the results) will provide the accuracy required for the purposes of paragraph 5 above in the range required for the purposes of paragraph 8 below.

(1) After the machine has weighed and discharged suitable material for at least five separate fillings of the load receptor by the normal automatic process, the process shall be stopped with the load receptor empty; and the inspector shall—
(a) ensure that the individual weight indicating device is set to zero or a given point; and
(b) set the totalisation indicating device to zero or record the indicated total.
(2) The automatic process shall be restarted so that the load receptor is filled and automatically weighed; and before any material is discharged the process shall be interrupted and the inspector shall determine the individual weight value.
(3) The automatic process shall be restarted so that the load receptor is discharged and automatically weighed; and before any further material is supplied to the load receptor the process shall be interrupted and the inspector shall determine the individual weight value.
(4) From the weight values recorded in accordance with sub-paragraphs (2) and (3) above the inspector shall determine the true net weight of the material discharged taking account of any calibration chart or graph prepared for the purposes of paragraph 7 above.
(5) The inspector shall then—
(a) determine the total true net weight of a number of separate loads in accordance with sub-paragraphs (2), (3) and (4) above to complete material tests as specified in sub-paragraphs (6), (7) and (8) below under normal conditions of use; and
(b) record the indication of the totalised weight of material in each test.
(6) A minimum of three individual tests (including at least one at minimum load and at least one at maximum capacity) shall be carried out, each test involving the weighing of a quantity of suitable material as nearly as practicable equal to the minimum totalised load marked on the machine.
(7) In the case only of a discontinuous totaliser first passed as fit for use for trade before 29th April 1996 and if the person submitting it for testing so requests, the test at maximum capacity under sub-paragraph (6) above may be carried out with twenty separate loads and the words “as nearly as practicable equal to the minimum totalised load” in that sub-paragraph shall not have effect.
(8) Unless already included in the tests carried out under sub-paragraphs (6) and (7) above two further tests (which shall include at least five weighing cycles and a quantity of material not less than the minimum totalised load), shall be carried out, one at the minimum load and one at the maximum capacity.
(9) For each group of tests referred to in sub-paragraph (5)(a) above, the inspector shall determine the material test error by ascertaining the difference between the weight of material determined as required by that sub-paragraph and the value of the weight of material obtained from the totalisation indicating device in accordance with sub-paragraphs (1)(b) and (5)(b) above.
