28、8442-4:1997 Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject f
29、or 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on
30、 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 bodies casting a vote. International Standard
31、IS0 8442-4 was prepared by the European Committee for Standardization (CEN) in collaboration with IS0 Technical Committee TC 186, Cutlery and table and decorative metal hollow-ware, in accordance with the Agreement on technical cooperation between IS0 and CEN (Vienna Agreement). IS0 8442 consists of
32、 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 preparation of food; - Part 2: Requirements for stainless steel and silver-plated cutlery; - Part 3: Requirements for silver-plated

36、 as the design, size, type of finish, blade flexibility or similar characteristics which can be readily identified by the purchaser at the point of sale. Attention is drawn to Directives of the European Community concerning materials and articles in contact with food, in particular to Directives EC
37、89/109 and EC 90/128. 1 Scope This Standard specifies the following requirements for gold plated cutlery: a) performance requirements for table cutlery (for example, knives, forks, spoons, carving sets, ladles, and other serving pieces); b) composition limits for base metals for cutlery; c) tests fo
38、r resistance to permanent deformation, firmness of handle attachment, hardness of blades, resistance to corrosion and the thickness and adhesion of gold coatings; d) three minimum thicknesses of gold plating: a first class, a second class, and a third class. This Standard specifies the method of def
39、ining gold deposits for each and every item and also test methods. This Standard does not apply to table cutlery which has only small areas of gold plate as inlays in non gold plated decoration. 2 Normative references This Standard incorporates by dated or undated reference, provisions from other pu
40、blications. These normative references are cited at the appropriate places in the text. and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this Standard only when incorporated in it by amendment or revision. Fo
