Foreword

This standard is identical with EN1186-3.2002 square test "plastic food contact materials and articles aqueous simulants overall migration Full immersion method "(in English). In order to meet China's national conditions and ease of use, this standard does the following editorial changes, the main differences are as follows. a) Remove the BSEN1186-3.2002 in the previous page, directory, foreword, introduction, appendix ZA, references and after page; b) In the "standard" instead of EN1186-3. in 2002, "This part of this standard"; c) use a decimal point instead of a decimal comma ",". ","; d) "ml" changed to "mL" representation; e) 3.1,3.4.1,3.5.1,3.5.2.2,4.1,4.4.1 and 4.5.1 respectively corresponding to each article BSEN1186-3 . section 2002 The 3.1,3.4.1,3.5.1,3.5.2.2,4.1,4.4.1 and 4.5.1 paragraphs; EN1186-1 f) in accordance with the referenced. the provisions for applying the provisions of No. 2002 contents be adjusted accordingly; g) in accordance with the provisions of the note number of national standards for the preparation of the requirements to be adjusted. Appendix A of this standard is an informative annex. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard is drafted by. People's Republic of China Jiangsu Entry-Exit Inspection and Quarantine Bureau. Involved in the drafting of the standard units.

1 Scope

This standard specifies the determination of food contact materials intended for food contact --- polymer material in an aqueous simulants overall migration test Test methods. Test by the specimen completely immersed in selected food simulants, at a selected time in temperatures up to the boiling point Carried out. This standard is most suitable for use in food contact materials --- polymer material films or sheets, but also for the majority of the appropriate size can be cut again Member of the container or article.
