21、ensils in contact with food”, the secretariat of which is held by BSI. This part of EN 13130 has been prepared within the Standards, Measurement and Testing project, MAT1-CT92-0006, “Development of Methods of Analysis for Monomers” and has been prepared by Subcommittee (SC 1) of TC 194 “Utensils in

22、contact with food“ as one of a series of test methods for plastics materials and articles in contact with foodstuffs. 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 an

23、d 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 Directives and amendments to existing Directives are expected which could change the legislative requirements which t

24、his 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 this standard. This part of EN 13130 should be read in conjunction with EN 13130-1. Further parts of EN 1313

25、0, 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 determination of specific migration from plastics materials into foodstuffs and food simulants and the deter

No 15970 and 4,4-dihydroxybiphenyl (DHBiph), HOC6H4C6H4OH, PM/Ref. No 16000, are monomers used in the manufacture of cer

39、tain plastics materials and articles intended to come into contact with foodstuffs. After manufacture, residual monomer(s) can remain in the polymer and may migrate into foodstuffs coming into contact with the plastics material or article. Method A describes the determination of 1,2-DHB, 1,3-DHB, 1,

40、4-DHB in food simulants. Method B describes the determination of DHBphen and DHBiph in food simulants. However, in cases where migration occurs, pay attention to the clear identification of the analyte, since under the conditions described in the method DHBphen and DHBiph have the same retention tim

41、e. NOTE The following should be taken into account when carrying out a migration test (see EN 13130-1). From migration experiments carried out for 10 d at 40 C it was recognized that 1,2-DHB, 1,3-DHB and 1,4-DHB are subject to losses due to chemical decomposition. The loss observed for 1,2-DHB was u

42、p to 20 % in aqueous simulants, that for 1,3-DHB was 5 % to 12 % in olive oil and that for 1,4-DHB was 14 % to 68 %, in both aqueous food simulants and olive oil. For DHBiph a small loss of 5 % to 12 % due to chemical decomposition was observed when using 15 % v/v aqueous ethanol as food simulant. T

43、he methods described have been pre-validated by collaborative trials with two laboratories. DD CEN/TS 13130-18:2005Licensed Copy: Wang Bin, na, Tue Aug 08 03:28:46 BST 2006, Uncontrolled Copy, (c) BSI6 1 Scope This document, part of EN 13130, specifies two methods as follows. Method A is an analytic

44、al procedure for the determination of the monomers 1,2-DHB, 1,3-DHB and 1,4-DHB in the food simulants water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and olive oil. The levels of monomer determined are expressed in milligrams of monomer per kilogram of food simulant. The method is appro

45、priate for the quantitative determination of 1,2-DHB and 1,3-DHB at a minimum level of 0,15 mg/kg in food simulants and, of 1,4-DHB at a minimum level of 0,10 mg/kg in food simulants. Method B is an analytical procedure for the determination of DHBphen and DHBiph in the food simulants water, 3 % w/v

46、 aqueous acetic acid, 15 % v/v aqueous ethanol and olive oil. The method is appropriate for the quantitative determination of DHBphen or DHBiph at minimum levels of 0,2 mg/kg and 0,25 mg/kg, respectively, in food simulants. NOTE The methods should also be applicable to other aqueous food simulants a

47、s well as to the other fatty food simulants e.g. sunflower oil, corn oil or a mixture of synthetic triglycerides.
