14、 Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, BS EN 15777:2009EN 15777:2009 (E) 4 Introduction This European Standard covers a test method for determination of phthal

15、ates in textile articles. Phthalates are commonly used as plasticizers in polymers. Toxicological concern 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 continu

16、e to be of concern to consumers. Phthalates are an issue for textile manufacturers and retailers due to their 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 scop

17、e of this legislation, that could be covered by the General Products Safety Directive (2001/95/EC) 2. WARNING 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

18、its use. It is the responsibility of the user to establish appropriate safety and health practices and to 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 no

19、t observed. It refers only to technical suitability and does not absolve the user from legal obligations 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 a

20、mounts of phthalates have shown damage to the liver, the kidneys, the lungs, and the developing testes. IMPORTANT It is absolutely essential that tests conducted according to this European Standard be carried out by suitably trained staff. BS EN 15777:2009EN 15777:2009 (E) 5 1 Scope This standard sp

21、ecifies 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 defi

22、nitions 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 stand

23、ard they 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 tr

24、eated 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. Use a scalpel or other appropriate cutting tool to cut two representative specimens into small pieces. 4 Apparatus and re

30、ted 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 phthalate plasticizer content is calculated by weight with Gas Chromatography-Mass-Spectrometry (GC

31、-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 in n-hexane. 5.2.2 Standard solution. Prepare a series of individual stock standard solution

32、s of the individual phthalate in n-hexane as shown in Table 1.

33、xane. Use at least five appropriate dilutions of the calibration sets to create calibration graphs and add to 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 phthala

34、tes Prepare the appropriate amount of internal standard solution. Weigh accurately (2,0 0,1) g of the pieces 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 appr

35、oximately 50 ml of n-hexane into the flask. Reflux gently for 4 h. Allow sufficient time for the n-hexane to 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 a

36、dd appropriate volume of internal standard solution and perform GC-MS analysis. Prepare if necessary further 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 spec

37、imen is very low, it will be necessary to increase the weight and/or concentrate the extract in order to reach 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 inte

38、rpolate the concentration of the phthalate in g/ml correcting for any dilutions. Subtract the blank concentration 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 specim

39、en (g); a is the concentration of the individual phthalate of blank solution (g/ml); b is the concentration 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.
