Regulation 136
Subject to paragraph (2) of this regulation, every automatic weighing machine shall be subjected to the following test (hereinafter referred to as “test A”), that is to say—
by weighing consecutively on the machine 20 separate loads (hereinafter referred to as “test loads”) selected for the purpose by the inspector, and then re-weighing the same loads on another weighing instrument:
Provided that, if the inspector thinks fit, he may so weigh and re-weigh more than 20 separate loads of which any 20 separate loads consecutively so weighed and re-weighing may be treated as the test loads; or
in any case where the aforementioned testing procedure is not practicable, by directly applying to the machine the appropriate working standard weights.
In the case of a totalising weighing machine, the provisions of subparagraph (a) of the preceding paragraph shall apply as if for any reference to “20 separate loads” there were substituted a reference to “40 separate loads”; and in such case the said test loads shall be made up as follows:—
10 loads each equal to the minimum load which the machine is constructed to weigh;
10 loads each equal to the capacity of the machine;
20 loads each equal to the mean between the said minimum load and the load equal to the capacity of the machine.
