適用范圍：1.1 This standard (First Revision) prescribes two methods for the quantitative chemical analysis of binary mixtures, in any textile form, such as fibre, yarn or fabric, of secondary cellulose acetate with cotton, wool, silk, regenerated cellulose, regenerated protein, polyamide, polyester, acrylic and glass fibres.NOTE — Before conducting an analysis according to this standard, the fibres present in the mixture should be identified (see IS 667 : 1981) and the sample to be analysed should be freed from all non-fibrous matter (see IS 9068 : 1979 ). Dye in the dyed fibre is considered to be an integral part of the fibre and is not to be removed.1.1.1 The methods prescribed in this standard are not applicable to mixtures containing modacrylic fibre, nor to mixtures containing partially acetylated cellulose acetate fibres.
