BS EN ISO 1833-20:2019
This standard BS EN ISO 1833-20:2019 Textiles. Quantitative chemical analysis is classified in these ICS categories:
- 59.060.20 Man-made fibres
- 59.060.01 Textile fibres in general
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.
It is also possible to analyse mixtures containing certain elastane fibres by using the test methods described in ISO 1833‑12 or ISO 1833‑21.
