标准范围

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.
