Gives material and performance criteria for cutlery with non-metallic handles. Requirements are given for stainless-steel and silver-plated nickel-silver or silver-plated stainless steel cutlery. Cutlery made from aluminium, precious metal, non-stainless steel, plastics, or which are gold- or chromium- plated are not included. Composition limits are defined for non- ferrous metals and steels for cutlery. Requirements are given for non-metal handles made from common, but not exotic materials, eg. mother-of-pearl or ivory, as well as cutlery that may be used in dishwashers. With regards to silver-plated cutlery, three minimum thicknesses are defined, first, second and third class.

This British Standard specifies material and performance requirements for cutlery with non-metallic handles intended for use at the dining table. It includes knives, forks, spoons, carving sets, ladles and other serving pieces.

Requirements are specified for stainless steel cutlery and silver-plated nickel-silver or silver-plated stainless steel cutlery. This standard does not cover cutlery wholly made of precious metals, aluminium, non-stainless steel or that made entirely of plastics, nor does it cover gold-plated or chromium-plated cutlery except for chromium-plated sharpening steels. However, cutlery incorporating sterling silver caps and ferrules or unplated nickel-silver rivets and caps are within the scope of this standard.

Composition limits are specified for steels and non-ferrous metals for cutlery.

Requirements are specified for non-metal handles made from the more commonly used materials (see 4.2.4), but not those made from exotic materials such as ivory or mother-of-pearl. The standard includes requirements for cutlery with non-metal handles for use in a dishwashing machine.

In the case of silver-plated cutlery, three minimum average thicknesses are specified, first, second and third class, with decreasing thickness of the silver deposit.
