The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a

19、 subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commissio

20、n (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should

21、 be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

25、 plasticizers in polymers. Phthalates are an issue for textile manufacturers and retailers due to their use within motifs, coated fabrics, plastisol prints, buttons, etc.Phthalates are controversial because high doses of many phthalates have shown hormonal activity in rodent studies. Studies on rode

26、nts involving large amounts of phthalates have shown damage to the liver, the kidneys, the lungs, and the developing testes.Due to their potential effect as endocrine disruptors, some of the listed phthalates are toxic in reproduction. The listed phthalates are based on those which have been restric

27、ted in some regulations (e.g. in the European Union). ISO 2014 All rights reserved vBS EN ISO 14389:2014BS EN ISO 14389:2014Textiles Determination of the phthalate content Tetrahydrofuran methodWARNING This International Standard calls for the use of substances and/or procedures that might be injuri

28、ous to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. It has been assumed in the drafting of this International Standard that the execution of its provisions is ent

29、rusted to appropriately qualified and experienced operators.1 ScopeThis International Standard specifies a method of determining phthalates in textiles with gas chromatographymass spectrometry (GC-MS) with mass selective detector.This International Standard is applicable to textile products where th

30、ere is a risk of the presence of some phthalates.2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1plasticized or softened materialplastic material that is treated with chemicals to make it more flexibleNote 1 to entry: For this specific Internati

32、ecimen obtained by mixing pieces of all the different treated parts and colours3 PrincipleThe phthalates are extracted from textile specimen by ultrasonic generator with tetrahydrofuran. As the plastic polymer is partially or completed dissolved, the phthalate extraction is followed by the precipita

33、tion of the dissolved polymer using the appropriate solvent (acetonitrile, n-hexane, etc.). After centrifugation and dilution of the extract to volume, gas chromatographymass spectrometry (GC-MS) is used to identify individual phthalates in the specimen and quantify them by using an internal standar

Allow glassware to cool down before use.Avoid direct contact between the samples and glassware and/or equipment used in order to

40、minimize cross-contamination. Glassware, after washing, should be given an extra rinse with 0,1 N nitric acid, water and finally with acetone. Glassware should be completely dried before use. To avoid contamination, do not use any plastic container (e.g. for water).6.1 Preparation of standard soluti

41、ons6.1.1 Internal standard solutionPrepare a 1 000 mg/l stock standard solution of the internal standard in the solvent used for the precipitation (4.2) after the ultrasonic extraction (see 6.2).6.1.2 Preparation of stock standard solutionsPrepare a series of individual stock standard solutions of t

42、he individual phthalate ester in the solvent used for the precipitation as shown in Table 1.For example, weigh 50,0 mg of a phthalate in a 50 ml volumetric flask and fill the volumetric flask up to the mark with the solvent used for the precipitation and mix thoroughly to dissolve completely the sub

This saves time and effort when preparing calibration solutions. DINP, DIDP and DIHP have overlapping peak

44、s. It is recommended to make up these stock standard solutions separately, as their calibration solutions have to be made in higher (5x) concentrations than for the other phthalates because of their multi-peak nature. Hence, the higher limit of detection in Annex B.6.1.3 Preparation of the calibrati

45、on solutionsFrom the stock standard solutions, prepare at least five appropriate phthalate calibration solutions (example of concentrations at 1 mg/l, 3 mg/l, 15 mg/l, 30 mg/l and 90 mg/l as described in the Table 2), each containing an equal amount of the target phthalates (4.4 through 4.13) and an

46、 amount of internal standard (4.3) in a mixture of tetrahydrofuran and the solvent used for the precipitation, mixed by volume at a ratio of 1:2 (33 parts tetrahydrofuran to 66 parts of the other solvent), as shown in Table 2. Each calibration solution should have a final internal standard concentra

47、tion of 5 mg/l. Prepare one calibration blank. Analyse the calibration solutions and calibration blank with the GC-MS. Qualitatively analyse the result to ensure proper retention times and the absence of contamination and built up the calibration curve. ISO 2014 All rights reserved 3BS EN ISO 14389:
