ISO 1833-1:2020
Textiles — Quantitative chemical analysis — Part 1: General principles of testing
This document specifies a common method for the quantitative chemical analysis of various mixtures of fibres. This method and the methods described in the other parts of ISO 1833 are applicable, in general, to fibres in any textile form. Where certain textile forms are excepted, these are listed in the scope of the appropriate part.
