  "text": "(1) Working standard capacity measures provided pursuant to section 5(1) of the Act for use by inspectors of weights and measures shall be tested by one of the following methods:—\nMethod 1\n(a) where the test relates to an indicated imperial measurement not exceeding 1 gal or an indicated metric measurement not exceeding 5 1, by transfer of water from an equivalent local standard capacity measure;\n(b) in any other case by transfer of water from a local standard capacity measure of maximum possible capacity in relation to the working standard used the requisite number of times;\nMethod 2\nby pouring water of a known temperature into the measure under test, when the measure is resting on a horizontal surface—\n(a) where the nominal capacity of the measure defined by a line, until the bottom of the meniscus coincides with the top of that line or with the top of any graduation line or tolerance mark being tested; or\n(b) where the nominal capacity of the measure is defined by its brim, until the surface water coincides with the brim;\nand in either case determining the weight of the water on a suitable weighing machine (the discrimination threshold of which in grams shall not be more than one-fifth of the equivalent amount in millilitres of the appropriate limit of error set out in Schedule 1 to these Regulations) and calculating therefrom the capacity of the measure in accordance with British Standard 1797: 1968 or British Standard 6696: 1986.\n(2) A working standard capacity measure shall be tested as a measure of any amount in Schedule 3 to the Act which it is designed to measure and the accuracy of any tolerance marks adjacent to any graduation tested shall also be tested.",
