The work of preparing International Standards is normally
17、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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the wo
18、rk. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. 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 Inte
19、rnational Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. 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 t
20、he 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 1833-14 was prepared by Technical Committee ISO/TC 38, Textiles. This first edition of ISO 1833-14 cancels and replaces Clause 13 of ISO 1833:1977. I
21、SO 1833:1977 will be cancelled and replaced by ISO 1833-1, ISO 1833-3, ISO 1833-4, ISO 1833-5, ISO 1833-6, ISO 1833-7, ISO 1833-8, ISO 1833-9, ISO 1833-10, ISO 1833-11, ISO 1833-12, ISO 1833-13, ISO 1833-14, ISO 1833-15, ISO 1833-16, ISO 1833-17, ISO 1833-18 and ISO 1833-19.

31、d, to determine the percentage of acetate, after removal of non-fibrous matter, in textiles made of mixtures of acetate and certain chlorofibres or after-chlorinated chlorofibres. 2 Normative references The following referenced documents are indispensable for the application of this document. For da
32、ted 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 principles of testing 3 Principle The acetate is dissolved out from a known dr
33、y mass of the mixture, with glacial acetic acid. The residue is collected, washed, dried and weighed; its corrected mass is expressed as a percentage of the dry mass of the mixture. The percentage of acetate is found by the difference. 4 Reagents Use the reagents described in ISO 1833-1 together wit
34、h that given in 4.1. 4.1 Glacial acetic acid, distilling at 117 C to 119 C. SAFETY PRECAUTIONS The harmful effects of this reagent shall be borne in mind, and full precautions shall be taken during use.

35、atus described in ISO 1833-1 together with those given in 5.1 and 5.2. 5.1 Conical flask, minimum capacity 200 ml, glass-stoppered. 5.2 Mechanical shaker. 6 Test procedure Follow the general procedure given in ISO 1833-1, and then proceed as follows. To the specimen contained in the conical flask, a
36、dd 100 ml of glacial acetic acid per gram of specimen. Insert the stopper and shake the flask for 20 min on the mechanical shaker. Decant the supernatant liquid through the weighed filter crucible. Repeat the treatment twice using 100 ml of fresh reagent each time, making three extractions in all. T
37、ransfer the residue to the filter crucible, drain using suction, and rinse the crucible and residue with 100 ml of acetic acid and then three times with water. After each rinse, allow the liquor to drain through the crucible for 2 min before draining using suction. Finally, dry the crucible and resi
38、due, 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 On a homogeneous mixture of textile materials, the confidence limits of the results obtained by this method are not
39、 greater than 1 for the confidence level of 95 %.
