PART III LIQUID CAPACITY MEASURES

Materials and principles of construction
17 1 Liquid capacity measures, made of copper or copper alloys shall be well tinned all over the inside; on plated measures the coating shall show no signs of peeling.
2 On measures on which there are strengthening ribs or bands, such ribs or bands shall not take such a form as to show, by indentation or otherwise, any divisions on the measure which, in the opinion of the inspector, might reasonably be mistaken for graduations.
