20、eration of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accorda

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires

The method of manual separation should be used
34、whenever possible, since it generally gives more accurate results than the chemical method. It can be used for all textiles whose component fibres do not form an intimate mixture, as, for example, in the case of yarns composed of several elements each of which is made up of one type of fibre, or fab
35、rics in which the warp is of a different type of fibre from the weft, or knitted fabrics capable of being unravelled and made up of yarns of different types. In general, the methods for quantitative chemical analysis of ternary fibre mixtures are based on the selective solution of the individual com
36、ponents of the mixture. Four variants of this procedure are possible. Variant 1: Using two different test specimens, component (a) is dissolved from the first test specimen and component (b) from the second test specimen. The insoluble residues of each test specimen are weighed and the percentage of
37、 each soluble component is calculated from the respective losses in mass. The percentage of the third component (c) is calculated by difference. Variant 2: Using two different test specimens, a component (a) is dissolved from the first test specimen, and two components (a and b) from the second test
38、 specimen. The insoluble residue of the first test specimen is weighed and the percentage of the component (a) is calculated from the loss in mass. The insoluble residue of the second test specimen is weighed: it corresponds to component (c). The percentage of the third component (b) is calculated b
39、y difference. Variant 3: Using two different test specimens, two components (a and b) are dissolved from the first test specimen and two components (b and c) from the second test specimen. The insoluble residues correspond to the two components (c) and (a) respectively. The percentage of the third c
40、omponent (b) is calculated by difference. Variant 4: Using only one test specimen, one of the components is removed, after which the insoluble residue formed by the two other fibres is weighed and the percentage of the soluble component is calculated from the loss in mass. One of the two fibres of t
41、he residue is dissolved, the insoluble component is weighed and the percentage of the second soluble component is calculated from the loss in mass. Where a choice is possible, it is advisable to use one of the first three variants. Where chemical analysis is used, take care to choose methods prescri
42、bing solvents which dissolve only the required fibre or fibres, and leave undissolved the other fibre or fibres. By way of example, Annex B contains a certain number of ternary mixtures, together with methods for analysing binary mixtures which can, in principle, be used for analysing these ternary
43、mixtures. In order to reduce the possibility of error to a minimum, it is recommended that, whenever possible, chemical analysis using at least two of the four above-mentioned variants should be made. Mixtures of fibres used during processing and, to a lesser extent, in finished textiles may contain
44、 non-fibrous matter such as fats, waxes or dressings, or water-soluble matter either occurring naturally or added to facilitate processing. Non-fibrous matter should be removed before analysis. A method of pre-treatment for removing oils, fats, waxes and water-soluble matter is given in ISO 1833-1:2
45、006, Annex A. In addition, textiles may contain resins or other matter added to confer special properties. Such matter, including dyestuffs in exceptional cases, may interfere with the action of the reagent on the soluble components and/or it may be partially or completely removed by the reagents. L

If it is impossible to remove such added matter, t
47、he methods for quantitative chemical analysis given in Annex B are no longer applicable. Dye in dyed fibre is considered to be an integral part of the fibre and is not removed. Analyses are conducted on the basis of dry mass and a procedure is given for its determination. The result is expressed by
48、reference to the dry mass or by reference to this mass after application of the conventional recovery rate. Before proceeding with any analysis, all the fibres present in the mixture should be identified. In some chemical methods, the insoluble components of a mixture may be partially dissolved in t
49、he reagent used to dissolve the soluble component or components. Whenever possible, reagents have been chosen that have little or no effect on the insoluble fibres. If a loss in mass is known to occur during the analysis, the result should be corrected; correction factors are given for this purpose. These factors have been determined in several laboratories by treating, with the appropriate reagent as specified in the method of analysis, fibres cleaned by the pre-treatment. These correction factors app
