17、rganization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been estab

18、lished 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 Commission (IEC) on all matters of electrotechnical standardizat

19、ion. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting

20、. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such p

31、e chemical analysis Part 17: Mixtures of chlorofibres (homopolymers of vinyl chloride) and certain other fibres (method using sulfuric acid) 1 Scope This part of ISO 1833 specifies a method, using sulfuric acid, to determine the percentage of chlorofibres, after removal of non-fibrous material, in t

32、extiles made of binary mixtures of chlorofibres based on homopolymers of vinyl chloride (after-chlorinated or not) and cotton, viscose, cupro, modal, acetate, triacetate, polyamide, polyester, certain acrylic and certain modacrylic fibres. The modacrylics concerned are those which give a limpid solu

33、tion when immersed in concentrated sulfuric acid ( = 1,84 g/ml). This method can be used, particularly in place of the methods described in ISO 1833-12 and ISO 1833-13, in all cases where a preliminary test shows that the chlorofibres do not dissolve completely either in dimethylformamide or in the

34、azeotropic mixture of carbon disulfide and acetone. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including

35、 any amendments) applies. ISO 1833-1, Textiles Quantitative chemical analysis Part 1: General principles of testing 3 Principle The constituent other than the chlorofibre is dissolved from a known dry mass of the mixture with concentrated sulfuric acid ( = 1,84 g/ml). The residue, consisting of the

36、chlorofibre, is collected, washed, dried and weighed; its mass, corrected if necessary, is expressed as a percentage of the dry mass of the mixture. The percentage of the second constituent is obtained by the difference. 4 Reagents Use the reagents described in ISO 1833-1 together with those given i

37、n 4.1, 4.2 and 4.3. 4.1 Sulfuric acid, concentrated ( = 1,84 g/ml). BS EN ISO 1833-17:2010ISO 1833-17:2006(E) 2 ISO 2006 All rights reserved4.2 Sulfuric acid, 50 % (mass fraction) aqueous solution. Prepare this reagent by adding carefully, while cooling, 400 ml of sulfuric acid (4.1) to 500 ml of di

38、stilled water. After cooling this solution to room temperature, dilute the solution to 1 l with water. 4.3 Ammonia, dilute solution. Dilute 60 ml of concentrated ammonia solution ( = 0,880 g/ml) to 1 I with distilled water. 5 Apparatus Use the apparatus described in ISO 1833-1 together with those gi

39、ven in 5.1 and 5.2. 5.1 Conical flask, of minimum capacity 200 ml, glass stoppered. 5.2 Glass rod, with flattened end. 6 Test procedure Follow the general procedure given in ISO 1833-1, and then proceed as follows. To the specimen contained in the flask, add 100 ml of the sulfuric acid (4.1) per gra

40、m of specimen. Allow the contents of the flask to remain at room temperature for 10 min, and during that time, stir the test specimen occasionally by means of the glass rod. If a woven or knitted fabric is being treated, wedge it between the wall of flask and the glass rod and exert a light pressure

41、 in order to separate the material dissolved by the sulfuric acid. Decant the liquid through the weighed filter crucible. Add a fresh portion of 100 ml of the sulfuric acid (4.1) to the flask and repeat the same operation. Transfer the contents of the flask to the filter crucible, and transfer the f

42、ibrous residue there with the aid of the glass rod. If necessary, add a little concentrated sulfuric acid (4.1) to the flask in order to remove any fibres adhering to the wall. Drain the filter crucible using suction. After emptying or changing the filter-flask, wash the residue in the crucible succ

43、essively with the 50 % sulfuric acid solution (4.2), the distilled or deionized water, the ammonia solution, and finally with the distilled or deionized water, draining the crucible using suction after each addition until the water drained from the crucible is neutral. Do not apply suction during th

44、e washing operation, but only after the liquid has drained through the crucible. Finally, dry the crucible and residue, then cool and weigh them. 7 Calculation and expression of results Calculate the results as described in the general instructions of ISO 1833-1. The value of d is 1,00. 8 Precision

45、For homogeneous mixtures of textile materials, the confidence limits of results obtained by this method are not greater than 1 for the confidence level of 95 %.
