16、006 All rights reserved iiiForeword ISO (the International Organization 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
17、 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 International Electrotechnical Comm
18、ission (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 Standards adopted by the technic
19、al 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 subject of patent rights. ISO sha

This first edition of ISO 1833-8 cancels and replaces Clause 7 of ISO 1833:1977. ISO 1833:1977 will be cancelled and replaced by ISO 1833-1, ISO 1833-3, ISO 1

31、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 latest edition of the referenced document (inc
32、luding 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 aqueous acetone. The residue is collected, washed, dried, and weighed; its corrected mas
33、s 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 with that given in 4.1. 4.1 Acetone, aqueous solution, 70 % (volume fraction). Dilute 700 ml of acetone to 1 I with water.
34、 5 Apparatus Use the apparatus 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.

35、en in ISO 1833-1, and then proceed as follows. To the specimen contained in the conical flask, add 80 ml of aqueous acetone per gram of specimen, shake the flask for 1 h on a mechanical shaker, and then decant the liquid through the weighed filter crucible. Add 60 ml of aqueous acetone to the residu
36、e in the flask, shake by hand and decant the liquid through the filter crucible. Repeat this treatment twice more, on the last occasion transferring the fibres to the crucible. Wash any residual fibres into the crucible with aqueous acetone and drain using suction. Refill the crucible with aqueous a
37、cetone and allow it to drain under gravity. 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 instructions of ISO 1833-1.
