19、n 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 established has the right to be represented on that committee.

20、 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 standardization. International Standards are drafted in accordance wi

21、th 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. Publication as an International Standard requires appro

22、val 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 patent rights. ISO 1833-12 was prepared by Technical Commi

34、formamide) 1 Scope This part of ISO 1833 specifies a method, using dimethylformamide, to determine the percentage of acrylic, modacrylic, chlorofibre or elastane, after removal of non-fibrous matter, in textiles made of binary mixtures of acrylic, certain modacrylics, certain chlorofibres, certain e

35、lastanes and animal fibres, cotton (scoured, kiered or bleached), viscose, cupro, modal, polyamide, polyester or glass fibres. It is applicable to animal hair, wool and silk dyed with pre-metallized dyes, but not to those dyed with after-chrome dyes. 2 Normative references The following referenced d

36、ocuments 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 any amendments) applies. ISO 1833-1, Textiles Quantitative chemical analysis Part 1: General princip

37、les of testing 3 Principle The acrylic, modacrylic, chlorofibre or elastane is dissolved out from a known dry mass of the mixture, with dimethylformamide at 90 C to 95 C. The residue is collected, washed, dried and weighed; its mass, corrected if necessary, is expressed as a percentage of the dry ma

38、ss of the mixture, and the percentage of acrylic, modacrylic, chlorofibre or elastane is found by the difference. 4 Reagents Use the reagents described in ISO 1833-1 together with that given in 4.1. 4.1 Dimethylformamide, boiling point 152 C to 154 C. SAFETY PRECAUTIONS The toxic effects of this rea

39、gent shall be borne in mind, and full precautions shall be taken during use.

40、1 together with those given in 5.1 and 5.2. 5.1 Conical flask, minimum capacity 200 ml, glass-stoppered. 5.2 Heating apparatus, suitable for maintaining the temperature of the flask within the limits 90 C to 95 C. 6 Test procedure Follow the general procedure given in ISO 1833-1, and then proceed as

41、 follows. To the specimen contained in the conical flask, add 150 ml of dimethylformamide per gram of specimen. Insert the stopper, shake the flask to wet out the specimen and heat the flask for 1 h at 90 C to 95 C. If there are difficulties in dissolving the acrylic portion of the specimen complete

42、ly, add an extra volume of 50 ml of dimethylformamide. Shake the flask and contents gently by hand five times during this period. Decant the liquid through a weighed filter crucible, retaining the fibres in the flask. Add a further 60 ml of dimethylformamide to the flask and heat it for 30 min at 90

43、 C to 95 C, shaking the flask and contents gently by hand twice during this period. Filter the contents of the flask through the filter crucible using suction. Transfer any residual fibres to the crucible by washing out the flask with water. Drain the crucible using suction. Wash the residue twice w

44、ith hot water by filling the crucible, allowing it to drain under gravity, and then drain using suction. If the residue consists of polyamide or polyester fibre, dry the crucible and residue, then cool and weigh them. If the residue consists of animal fibre, cotton, viscose, cupro or modal fibre, tr

45、ansfer it with forceps to a 200 ml glass-stoppered flask, add 160 ml of water and allow the flask to stand for 5 min at room temperature, shaking the flask and contents vigorously at intervals. Decant the water through the crucible and repeat this washing process three more times. After the last was

46、h, filter the contents of the flask through the crucible using suction. Transfer any residual fibres to the crucible by washing out the flask with water. Finally, drain the crucible using suction, dry the crucible and residue, then cool and weigh them. 7 Calculation and expression of results Calcula
