This document was prepa
20、red 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 the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Nove
21、mber 2004, and conflicting national standards shall be withdrawn at the latest by November 2004.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 and the European Free Trade Association. This standard is intended to support Directives 2002/72/EC 1, 89/109/EEC 2
22、, 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 relating to plastics materials and articles intended to come into contact with foodstuffs is incomplete. Further Directive
23、s 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 this standard refer to the latest relevant published Directive(s) before commencement of a test or tests described in
24、this standard. EN 13130-7 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 substances subject to limitation, have been prepared, and others are in preparation, concerned with the determinati
