Phthalates are commonly used as plasticizers in polymers. Toxicological concern

17、 has arisen due to their potential effect as endocrine disruptors and some of the listed phthalates are toxic in reproduction. The level of media publicity will ensure that their use will continue to be of concern to consumers. Phthalates are an issue for textile manufacturers and retailers due to t

18、heir use within motifs, coated fabrics, plastisol prints, buttons, etc. There are textile articles that have to comply with the Directive 2005/84/EC 1 and also articles that fall outside the scope of this legislation, that could be covered by the General Products Safety Directive (2001/95/EC) 2. WAR

19、NING Persons using this European Standard should be familiar with normal laboratory practice. This European Standard does not claim to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to

20、 ensure compliance with any national regulatory conditions. This European Standard calls for the use substances and/or procedures that may be injurious to health if appropriate precautions are not observed. It refers only to technical suitability and does not absolve the user from legal obligations

21、relating to health and safety at any stage. Phthalates are controversial because high doses of many phthalates have shown hormonal activity in rodent studies. Studies on rodents involving large amounts of phthalates have shown damage to the liver, the kidneys, the lungs, and the developing testes. I

22、MPORTANT It is absolutely essential that tests conducted according to this European Standard be carried out by suitably trained staff.

23、s a test method for taking representative specimens, extraction of phthalates from the material and determination of phthalates by gas chromatography mass spectrometry. This standard applies to textiles articles, where there is a possibility of the presence of some phthalates. 2 Terms and definition

24、s For the purposes of this European Standard, the following terms and definitions apply. 2.1 blank application of the method without test specimen 2.2 plasticized or softened materials plastic material (coating, pigment print binder, etc) that is treated with chemicals (for this specific standard th

25、ey are phthalates) to make it more flexible 2.3 overall treated textiles textiles with a continuous finish, coating or print 2.4 locally treated textiles textile with a discontinuous finish, coating or print 2.5 representative specimen specimen obtained by mixing pieces of all the different treated

26、parts and colours 3 Preparation of the test specimens Remove the untreated mass of the specimen if possible (see Annex A). If the untreated mass cannot be removed, see 5.4.

32、t procedure 5.1 Principle The aim of the method is to extract phthalates in textiles and related accessories. This method uses Soxhlet extraction apparatus with n-hexane as solvent. However, any apparatus giving equivalent extraction as with Soxhlet can be used. The total n-hexane extractable phthal

33、ate plasticizer content is calculated by weight with Gas Chromatography-Mass-Spectrometry (GC-MS) detection to identify and quantify individual phthalates. 5.2 Reagent (standard solutions) 5.2.1 Preparation of the internal standard solution. Prepare a 500 g/ml stock solution of the internal standard

34、 in n-hexane. 5.2.2 Standard solution. Prepare a series of individual stock standard solutions of the individual phthalate in n-hexane as shown in Table 1. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 15/01/2010 02:15, Uncontrolled Copy, (c) BSIBS EN 15777:2009EN 15777:2009 (E) 7 Table 1 S

35、tock solutions Phthalate DIDP DINP DBP BBP DNOP DEHP Concentration, g/ml 1000 1000 200 200 200 200 From the stock standard solutions prepare appropriate phthalate calibration solutions in n-hexane. Use at least five appropriate dilutions of the calibration sets to create calibration graphs and add t

36、o each an appropriate amount of internal standard and perform GC-MS analysis. NOTE DIDP and DINP overlap in the chromatogram, choose target ions indicated in Annex B. 5.3 Extraction of phthalates Prepare the appropriate amount of internal standard solution. Weigh accurately (2,0 0,1) g of the pieces

37、 of a representative specimen into a Soxhlet thimble and add a filter paper disc to the top of the thimble. Extract every sample in duplicate and run a blank to control contamination. Add approximately 50 ml of n-hexane into the flask. Reflux gently for 4 h. Allow sufficient time for the n-hexane to

38、 cool. Transfer the extract to a 100 ml volumetric flask. Rinse the flask with 2 aliquots of 20 ml n-hexane. Make up to the mark. Transfer a known volume into a suitable GC sampling vial and add appropriate volume of internal standard solution and perform GC-MS analysis. Prepare if necessary further

39、 diluted solutions using the original solution and repeat the analysis after added the appropriate volume of internal standard solution. NOTE In some cases where the corrected mass of the specimen is very low, it will be necessary to increase the weight and/or concentrate the extract in order to rea

40、ch at least 3 times the detection limit. 5.4 Calculation of results From the calibration graph determine the response of each phthalate, corrected for the internal standard peak area, and interpolate the concentration of the phthalate in g/ml correcting for any dilutions. Subtract the blank concentr

41、ation from the specimen concentration. 10000ma - b=VP (1) where P is the percentage of the individual phthalate; V is the volume of the volumetric flask (ml); m is the corrected mass of specimen (g); a is the concentration of the individual phthalate of blank solution (g/ml); b is the concentration

42、of the individual phthalate the specimen solution corrected for any dilutions (g/ml). If the corrected mass of test specimen cannot be obtained (see Annex A), give a remark in the test report.
