The work of preparing International Standards is normally carried out through ISO tec

17、hnical 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 work. ISO collaborates closel

18、y 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 International Standards. Draft

19、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 the elements of this documen

20、t may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1833-19 was prepared by Technical Committee ISO/TC 38, Textiles.

31、taken to avoid inhalation of asbestos dust. 1 Scope This part of ISO 1833 specifies a method, by heating, to determine the percentage of cellulosic fibre in textiles made of binary mixtures of cotton or regenerated cellulose and chrysotile and crocidolite asbestos. This method may be applicable to o

32、ther types of asbestos, subject to agreement between the interested parties. NOTE This method differs in principle from the general method based on selective solubility set out in ISO 1833-1. 2 Normative references The following referenced documents are indispensable for the application of this docu
