18、r 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. International organizations, governmenta
19、l 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 with the rules given in the ISO/IEC Directi
20、ves, 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 approval by at least 75 % of the member bodies
21、 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 1833-19 was prepared by Technical Committee ISO/TC 38, Textiles. This first edit

33、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 other t
34、ypes 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 document.
35、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 principles of testing 3 Principle The cellulosic fibres are removed from
36、 a known dry mass of the mixture by heating at (450 10) C for 1 h. The residue is weighed; its corrected mass is expressed as a percentage of the dry mass of the mixture. The percentage of cellulosic fibre is calculated by the difference. NOTE The preliminary removal of non-fibrous matter is not nec
37、essary. 4 Reagents Use the reagents described in ISO 1833-1.

38、those given in 5.1, 5.2 and 5.3. 5.1 Weighing bottle. 5.2 Crucible. 5.3 Electric furnace, with automatic temperature control at (450 10) C. 6 Sampling Take a laboratory test sample that is representative of the laboratory bulk sample and sufficient to provide all the specimens, each of about 5 g, th
39、at are required. NOTE Pre-treatment of the laboratory test sample, described in ISO 1833-1, is not applicable to the analysis of this mixture. 7 Test procedure Follow the general procedure given in ISO 1833-1, and then proceed as follows. Take from the laboratory test sample, a test specimen weighin
40、g about 5 g. Determine the dry mass of the test specimen accurately in a weighing bottle, transfer it to an open crucible of known mass and heat it in the electric furnace with automatic temperature control at (450 10) C for 1 h. Cool the crucible and its contents to room temperature in a desiccator
41、. Determine the mass of the crucible and residue within 2 min of its removal from the desiccator. 8 Calculation and expression of results Calculate the results as described in the general instructions of ISO 1833-1. The value of d is 1,02. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 26/05
