适用范围：This standard prescribes two methods for the quantitative chemical analysis of binary mixtures of silk and wool or hair in any textile form, such as fibre, yarn and fabric.NOTE — Before conducting an analysis according to this standard, the fibres present in the mixture should be identified [ see IS 667 : 1981 Methods for identification of textile fibres (first revision) ] and the sample to be analysed should be freed from all non-fibrous matter (see IS 9068 : 1979 Recommended methods for the removal of non-fibrous matter prior to quantitative analysis of fibre mixtures ). The dye in the dyed fibre is considered to be an integral part of the fibre and is not to be removed.
