BS EN ISO 1833-22:2021

This standard BS EN ISO 1833-22:2021 Textiles. Quantitative chemical analysis is classified in these ICS categories:

• 59.060.01 Textile fibres in general

This document specifies a method, using formic acid and zinc chloride, to determine the mass percentage of viscose or certain types of cupro or modal or lyocell, after removal of non-fibrous matter, in textiles made of mixtures of

• viscose or certain types of the cupro or modal or lyocell fibres

with

• flax fibres.

This document is not applicable to mixtures in which the flax fibre has suffered extensive chemical degradation, nor when the viscose, cupro, modal or lyocell fibre is rendered incompletely soluble by the presence of certain permanent finishes or reactive dyes that cannot be removed completely.
