4、 the method was not evaluated using recognized ring trial procedures. As a consequence there are no reproducibility data for the method. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained.Comments arising from the use of th

5、is Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion to a European standard. A review of this publication will be initiated 2 years after its publication by the European organization so that a decision can be taken o

6、n its status at the end of its 3-year life. Notification of the start of the review period will be made in an announcement in the appropriate issue of Update Standards.According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the

7、conversion into a European Standard, to extend the life of the Technical Specification or to withdraw it. Comments should be sent in writing to the Secretary of BSI Subcommittee CW/47/1 Migration from plastics, at British Standards House, 389 Chiswick High Road, London W4 4AL, giving the document re

19、tee CEN/TC 194 “Utensils 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

20、 194 “Utensils in 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

21、 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 Directives and amendments to existing Directives are expected which could change the legislative re

22、quirements 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 this standard. This part of EN 13130 should be read in conjunction with EN 13130-1. Furthe

23、r 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 determination of specific migration from plastics materials into foodstuffs and food simul

24、ants and the determination of specific monomers and additives in plastics. The parts of EN 13130 are as follows.

35、om. DD CEN/TS 13130-21:20055 Introduction Ethylenediamine (EDA), 1,2-Diaminoethane, C2H8N2or H2N-(CH2)2-NH2, PM/Ref. No 16960, and hexamethylenediamine (HMDA), 1,6-Diaminohexane, C6H16N2or H2N-(CH2)6-NH2, PM/Ref. No 18460 are monomers used in the manufacture of certain plastics materials and article

36、s intended to come into contact with foodstuffs. After manufacture, residual EDA monomer and HMDA monomer can remain in the polymer and may migrate into foodstuffs coming into contact with that plastics article. NOTE Stability tests in olive oil food simulant carried out under test conditions 10 d a

37、t 20 C and 10 d at 40 C indicated that EDA and HMDA cannot be recovered, presumably due to chemical reaction with the olive oil. Therefore, even though this analytical method works in principle with olive oil as a food simulant, the migration test using olive oil or another fat simulant can provide

38、false-negative results. Therefore, the method should only be applied in case of short exposure periods with olive oil and if applied, a recovery check with spiked olive oil applying the same time/temperature migration test conditions is recommended. Alternatively 95 % ethanol or iso-octane could be

39、used as substitute fatty food simulants. The method has been pre-validated by a collaborative trial with two laboratories. DD CEN/TS 13130-21:20056 1 Scope This document, part of EN 13130, specifies an analytical procedure for the determination of EDA monomer and HMDA monomer in the food simulants w

40、ater, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and olive oil as well as in the substitute food simulants 95 % v/v ethanol and iso-octane. The level of EDA monomer and HMDA monomer determined are expressed as milligram EDA per kilogram of food simulant and as milligrams HMDA per kilogram

41、 of food simulant. The method is appropriate for the quantitative determination of EDA at a minimum level of 1 mg per kilogram of food simulants and for the quantitative determination of HMDA at a minimum level of 0,5 mg per kilogram of food simulants. The method should also be applicable to other a

42、queous food simulants as well as to the other fatty food simulants sunflower oil and a mixture of synthetic triglycerides. 2 Normative references The following referenced documents are indispensable for the application of this document.

44、and food simulants and the determination of substances in plastics and the selection of conditions of exposure to food simulants. DD CEN/TS 13130-21:20057 3 Principle The level of EDA or HMDA in a food simulant is determined by derivatization of the free diamine, using ethyl chloroformate as derivat

45、ization agent followed by analysis of the resulting diurethane by gas chromatography using automated sample injection and flame ionization detection (FID). Quantification is achieved using propylenediamine (PDA) as an internal standard with calibration against relevant food simulants samples fortifi

46、ed with known amounts of EDA or HMDA. Confirmation of EDA or HMDA levels is carried out by combined gas chromatography/mass spectrometry (GC/MS) of the diurethane. 4 Reagents NOTE All reagents should be of recognized analytical quality unless otherwise stated. 4.1 Analytes 4.1.1 EDA (1,2-diaminoetha
