Weights and Measures Act 1985

12 (1) Weighing equipment (including weights) which weighs wholly or partly in drams may continue to be used for trade if it was first passed as fit for use for trade and stamped in accordance with the 1963 Act before 27th April 1978. E+W+S

(2) Nothing in sub-paragraph (1) above shall be taken as authorising the continued use for trade of the dram except in so far as the weight of the goods in drams or partly in drams is treated as having been made known to a prospective buyer by virtue of sections 45(1)(a) and 46 of this Act.

(3) Products and equipment necessary to complete or replace components or parts of equipment the continued use of which is authorised by sub-paragraph (1) above may be manufactured, placed on the market and used after the commencement of this Act, but this sub-paragraph shall not permit the replacement of weights, whether or not the weights form part of other weighing equipment.

(4) Without prejudice to sub-paragraphs (1) and (2) above, every pattern of weighing equipment—

(a) the certificate of approval in respect of which was, or is deemed to have been, granted under section 12 of the 1963 Act and was in force immediately before 27th April 1978, and

(b) which provides for weighing to be made wholly or partly in drams,

(including a pattern modified in accordance with an authorisation for the time being in force under that section) shall continue to be deemed modified to the extent necessary to require equipment of that pattern to weigh in fractions of an ounce in substitution for drams and fractions of a dram.
