28、ware.EN 1388-2:1996 BSI 1 July 2004 3 Introduction The problem of lead and cadmium release from ceramic ware requires effective means of control to ensure the protection of the population against possible hazards arising from the use of improperly formulated, applied and fired glazes and decorations

29、 on the food contact surfaces of ceramic ware used for the preparation, serving and storage of foodstuffs. NOTE Articles which are highly coloured or decorated on their food contact surfaces or which have a high surface area/volume ratio are more likely than other articles to release lead and/or cad

30、mium. The Council of the European Communities has adopted a specific Directive for the measurement of possible migration of lead and cadmium from ceramic articles which, in their finished state, are intended to come into contact with foodstuffs, or which are in contact with foodstuffs, and are inten

31、ded for that purpose. In Directive 84/500/EEC, Annex I describes “Basic rules for determining the migration of lead and cadmium”. In Annex II, atomic absorption spectroscopy is prescribed as the method of analysis. Technical Committee 194 of the European Committee for Standardization has undertaken

32、the task of setting up European Standards for methods of test for silicate surfaces on the basis of the Directive and to harmonize at the same time existing national standards. International Standard ISO7086-1 was considered in this work. Part 1 of this European Standard specifies the method of test

33、 for the determination of lead and cadmium released from ceramic surfaces. Because existing national standards have also established that this method of test is applicable to glass, glass ceramic and vitreous enamel silicate surfaces, this Part of the European Standard has been prepared also to spec

34、ify tests applicable to such silicate surfaces. An existing national standard includes a test for surfaces with which the mouth is intended to come into contact, and this European Standard also includes a method of test appropriate to such silicate surfaces. For homogeneous, i.e. undecorated or ungl

35、azed, glassware, such as that made from soda-lime-silicate glass or borosilicate glass, and glass ceramic ware intended to come into contact with foodstuffs, no raw materials containing lead and cadmium are used in the manufacture. An exception is crystal glass as defined in the EC Directive for Cry

36、stal Glass (69/493 EEC). From soda-lime-silicate glass and borosilicate glass any release of lead and cadmium can only result from impurities and normally will be below the current detection limits of flame atomic absorption spectrometry (FAAS) for lead and cadmium. For uncoloured, undecorated or un

37、glazed glass articles made from mass-produced soda-lime-silicate glass or borosilicate glass, it is not essential to test according to this European Standard. 1 Scope This European Standard specifies a reference method for determining the release of lead and cadmium from articles with silicate surfa

38、ces of glass, glass ceramic and vitreous enamel which are intended to come into contact with foodstuffs. This European Standard also applies to vitreous enamelled containers and to parts of equipment intended for industrial use with foodstuffs. This European Standard specifies also a method of test

39、for determining the release of lead and/or cadmium from a drinking rim; the drinking rim of ceramic articles can also be tested according to this method. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
