This Standard is applicable to such items as jugs, dis
21、hes, wine coolers, tea- and coffee-pots, trays and tureens. Requirements are specified for brass, copper, bronze, nickel-silver, pewter and stainless steel holloware with a light silver-plating and a lacquered coating. The standard does not cover holloware made entirely of precious metals, brass, ni
22、ckel-silver, stainless steel or made from ceramics or glass or non-stainless steel or zinc-based die cast. Composition limits are specified for the basic metals for fabrication of the holloware prior to silver-plating and lacquering. The standard does not include requirements for design, size or any
23、 other characteristics which are matters of personal choice or which can be readily assessed by the purchaser at the point of sale. 2 Normative references This Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropr
