Testing
136.—(1)
(a)
(b)in any case where the aforementioned testing procedure is not practicable, by directly applying to the machine the appropriate working standard weights.
(2) 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:—
(a)10 loads each equal to the minimum load which the machine is constructed to weigh;
(b)10 loads each equal to the capacity of the machine;
(c)20 loads each equal to the mean between the said minimum load and the load equal to the capacity of the machine.
137.—(1)
(2) For the purposes of test B, there shall be extracted from each of those test loads used in test A (the weight of which was found to exceed the relevant amount specified in paragraph (1) of this regulation) that single piece or item appearing to the inspector to be the largest single piece or item in that test load; and the machine shall then be subjected to test by re-weighing each such test load as so modified on another weighing instrument.
(3) This regulation shall not apply to automatic weighing machines of a capacity of 10 pounds or more, or to automatic weighing machines for use only for weighing solid fuel or for use only for weighing potato crisps, or to totalising weighing machines.
138. Parts I and XI of Schedule 2 hereto shall have effect for prescribing limits of error in relation to automatic weighing machines.
