标准范围
This document specifies a method using dimethylacetamide to determine the mass percentage of
elastane, after removal of non-fibrous matter, in textiles made of mixtures of:
— certain elastane fibres
with
— cotton, viscose, cupro, modal, lyocell, polyamide, polyester or wool fibres.
This method is not applicable when acrylic fibres are present.
