18、mmittee CEN/TC 194 “Utensils in contact with food”, the secretariat of which is held by BSI. This document was prepared by Subcommittee SC1 of TC 194 as one of a series of analytical test methods for plastics materials and articles in contact with foodstuffs. This European Standard shall be given th
19、e status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2004, and conflicting national standards shall be withdrawn at the latest by November 2004. This document has been prepared under a mandate given to CEN by the European Commission
20、 and the European Free Trade Association. This standard is intended to support Directives 2002/72/EC 1, 89/109/EEC 2, 82/711/EEC 3 and its amendments 93/8/EEC 4 and 97/48/EC 5, and 85/572/EEC 6. At the time of preparation and publication of this part of EN 13130 the European Union legislation relati
21、ng to plastics materials and articles intended to come into contact with foodstuffs is incomplete. Further Directives and amendments to existing Directives are expected which could change the legislative requirements which this standard supports. It is therefore strongly recommended that users of th
22、is standard refer to the latest relevant published Directive(s) before commencement of a test or tests described in this standard EN 13130-4 should be read in conjunction with EN 13130-1 Further parts of EN 13130, under the general title Materials and articles in contact with foodstuffs - Plastics s
23、ubstances subject to limitation, have been prepared, and others are in preparation, concerned with the determination of specific migration from plastics materials into foodstuffs and food simulants and the determination of specific monomers and additives in plastics. The other parts of EN 13130 are
24、as follows. Part 1: Guide to test methods for the specific migration of substances from plastics to foods and food simulants and the determination of substances in plastics and the selection of conditions of exposure to food simulants Part 2: Determination of terephthalic acid in food simulants Part
