The work of preparing International Standards is normally carried

19、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 work. ISO

20、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 Internationa

21、l 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 the eleme

After the removal of a component, the insoluble residue is weighed, and the proportio

33、n of soluble component is calculated from the loss in mass. This part of ISO 1833 gives the information which is common to the analyses, by this method, of all fibre mixtures, whatever their composition. This information should be used in conjunction with the other parts of ISO 1833; these parts con

34、tain the detailed procedures applicable to particular fibre mixtures. Where, occasionally, an analysis is based on a principle other than selective solution, full details are given in the appropriate part. Mixtures of fibres during processing and, to a lesser extent, finished textiles may contain fa

35、ts, waxes or dressings, either occurring naturally or added to facilitate processing. Salts and other water-soluble matter may also be present. Some or all of these substances would be removed during analysis, and calculated as the soluble-fibre component. To avoid this error, non-fibrous matter sho

36、uld be removed before analysis. A method of pre-treatment for removing oils, fats, waxes and water-soluble matter is given in Annex A of this part of ISO 1833. In addition, textiles may contain resins or other matter added to bond the fibres together or to confer special properties, such as water-re

37、pellence or crease-resistance. Such matter, including dyestuffs in exceptional cases, may interfere with the action of the reagent on the soluble component and/or it may be partially or completely removed by the reagent. This type of added matter may also cause errors and should be removed before th

38、e sample is analysed. If it is impossible to remove such added matter, the methods of analysis are no longer applicable. Dye in dyed fibres is considered to be an integral part of the fibre and is not removed. Most textile fibres contain water, the amount depending on the type of fibre and on the re

39、lative humidity of the surrounding air. Analyses are conducted on the basis of dry mass, and a procedure for determining the dry mass of test specimens and residues is given in this part of ISO 1833. The result is therefore obtained on the basis of clean, dry fibres. Provision is made for recalculat

40、ing the result on the basis of a) agreed allowances for moisture content1), b) agreed allowances for moisture and also for 1) fibrous matter removed in the pre-treatment, and 2) non-fibrous matter (for example, fibre dressing, processing oil, or size) that can be properly regarded as part of the fib

41、re as an article of commerce. In some methods, the insoluble component of a mixture may be partially dissolved in the reagent used to dissolve the soluble component. Where possible, reagents have been chosen that have little or no effect on the insoluble fibres. If loss in mass is known to occur dur

42、ing the analysis, the result should be corrected; correction factors for this purpose are given. These correction factors have been determined in several laboratories by treating, in the appropriate reagent as specified in the method of analysis, fibres cleaned by the pre-treatment. These correction

43、 factors apply only to undegraded fibres, and different correction factors may be necessary if the fibres have been degraded during processing. 1) The values to use are the conventional conditioning rates for the respective fibres, when rates exist. BS EN ISO 1833-1:2010EN ISO 1833-1:2010 (E) ISO 20

44、11viiThe procedures given apply to single determinations; at least two determinations on separate test specimens should be made, but more may be carried out if desired. Before proceeding with any analysis, all the fibres present in the mixture should have been identified. For confirmation, unless it

45、 is technically impossible, it is recommended that use be made of alternative procedures whereby the constituent that would be the residue in the standard method is dissolved out first. If it is practicable to separate the components of a mixture manually, the method described in Annex B should be u

46、sed in preference to the chemical methods of analysis given in the individual parts of ISO 1833.
