The work of preparing International Standards is normally carried out through ISO technical committe

29、es. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Inte

30、rnational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member b

31、odies casting a vote.International Standard ISO 8442-2 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 186, Cutlery and table and decorative metal hollow-ware, in accordance with the Agreement on technical cooperation between ISO and

32、CEN (Vienna Agreement).This first edition cancels and replaces ISO 8442:1988, which has been technically revised.ISO 8442 consists of the following parts, under the general title Materials and articles in contact with foodstuffs Cutlery and table holloware: Part 1: Requirements for cutlery for the p

33、reparation of food; Part 2: Requirements for stainless steel and silver-plated cutlery; Part 3: Requirements for silver-plated table and decorative holloware; Part 4: Requirements for gold-plated cutlery.

36、th performance and does not include requirements for design, size, type of finish, blade flexibility, or similar characteristics which are matters of personal choice or which can be readily assessed by the purchaser at the point of sale. In this Standard the thickness of silver deposit is stipulated

37、 for each and every item, in contrast to traditional methods which relate to an average of 12 or 24 items, amongst which some items can have a significantly lower thickness of silver coating.Attention is drawn to Directives of the European Community concerning materials and articles in contact with

38、food, in particular to Directives EC 89/109 and EC 90/128.1 ScopeThis part of this Standard specifies material, performance requirements and test methods for table cutlery (knives, forks, spoons, carving sets, ladles, childrens cutlery and other serving pieces).This Standard is applicable to stainle

39、ss steel cutlery and to silver-plated nickel silver, or silver-plated stainless steel, cutlery. It does not cover cutlery made wholly of precious metals, aluminium, non-stainless steel or that made entirely of nickel silver, nor does it cover gold-plated or chromium-plated cutlery.Three minimum thic

40、knesses of silver are specified for silver-plated cutlery.2 Normative referencesThis Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For date

41、d references, subsequent amendments to or revisions of any of these publications apply to this Standard only when incorporated in it by amendment or revision.

46、 knivesknives that do not have a sharpened blade because they are intended for use with soft foods and whose blades are therefore not made of martensitic stainless steel.
