<p>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:</p>
<p>— certain elastane fibres</p>
<p>with</p>
<p>— cotton, viscose, cupro, modal, lyocell, polyamide, polyester or wool fibres.</p>
<p>This method is not applicable when acrylic fibres are present.</p>
<p>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.</p>
