25、2 O BSI 01-2000 EN IS0 8442-11997 Introduction This standard, based on draft ISOTC 186 documents N 53 and N 54, does not cover those features of cutlery which are matters of choice for the user, such as the shape and size of knife or spatula blades. It is the intention that requirements for blade sh

26、arpness and edge retention are incorporated in this standard at a later date if reliable test methods are established for these properties. No meaningful test for the resistance of knives to fracture in use could be developed for the standard, but it is considered that this can be partially assessed

27、 from the appearance of cracks in the initial visual inspection, in the resistance to dropping requirements, the strength test requirements or in the corrosion test requirements. Attention is drawn to Directives of the European Community concerning materials and articles in contact with food, in par

28、ticular to Directives EC 77/99 and EC 89/109. 1 Scope This part of this Standard specifies material and performance requirements and test methods for metal cutlery and related implements intended for use in the preparation of food. Two grades of cutlery are specified: - a normal grade with corrosion

29、 resistant blades or prongs capable of withstanding dishwasher cleaning procedures; - a special grade with corrosion resistant blades capable of withstanding dishwasher cleaning procedures and sterilization processes. 2 Normative references This Standard incorporates by dated or undated reference, p

30、rovisions from other publications. 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 ame
