The work of preparing International Standards is normally carried out through ISO technical commit
17、tees. 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 work. ISO collaborates closely with the In
18、ternational 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 International Standards. Draft International
19、 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 the elements of this document may be the
20、subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1833-9 was prepared by Technical Committee ISO/TC 38, Textiles. This first edition of ISO 1833-9 cancels and replaces Clause 8 of ISO 1833:1977. ISO 1833:1977 will be cancelled and replaced

31、ter removal of non-fibrous matter, in textiles made of binary mixtures of acetate and triacetate fibres. 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
32、 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 fibre is dissolved out from a known dry mass of the mixture, with benzyl alcohol. The residue is collected,
33、 washed, dried and weighed; its corrected mass is expressed as a percentage of the dry mass of mixture. The percentage of acetate is found by the difference. 4 Reagents Use the reagents described in ISO 1833-1 together with those given in 4.1 and 4.2. 4.1 Benzyl alcohol. 4.2 Ethanol. BS EN ISO 1833-

35、ure of the flask at (52 2) C (for example water bath with thermostat). 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, add 100 ml of benzyl alcohol per gram of specimen. Insert the stopper and shake the f
36、lask vigorously on the mechanical shaker so that it plunges into the water bath, kept at a temperature of (52 2) C. Shake the flask for (20 1) min at this temperature. Filter the contents of the flask through the weighed filter crucible. Replace the residue in the flask by means of forceps, add to t
37、he flask a fresh portion of benzyl alcohol and shake as before at a temperature of (52 2) C for (20 1) min. Filter the contents of the flask through the same weighed filter crucible and repeat the cycle a third time with a third 100 ml portion of benzyl alcohol. Pour the liquid and the residue into
38、the same weighed filter crucible; wash any fibres from the flask into the crucible with an extra quantity of benzyl alcohol at a temperature of (52 2) C. Drain the crucible using suction. Transfer the fibres into a flask, rinse with ethanol and, after manual shaking, decant through the same filter c
39、rucible. Repeat this rinsing operation three times. Transfer the residue into the same filter crucible. Finally, drain the crucible using suction, dry the crucible and residue, then cool and weigh them. 7 Calculation and expression of results Calculate the results as described in the general instruc
40、tions 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 greater than 1 for the confidence level of 95 %.
