This document specifies methods of quantitative analysis of various ternary mixtures of fibres.
The field of application of each method for analysing mixtures, specified in the parts of ISO 1833, indicates the fibres to which the method is applicable.
This document is applicable to mixtures of fibres with more than three components provided that the combination of test methods leads back to simple cases of fibre mixtures. Table B.1 illustrates the typical ternary mixtures and their applied corresponding parts of the ISO 1833 series.
