<p>This document specifies the qualitative analysis for cupro and lyocell using the two methods separately</p>
<p>— scanning electron microscope (SEM) method based on the application of ISO 20705, and</p>
<p>— spectral analysis method.</p>
<p>These testing methods are applied only for cupro and lyocell, or those blends. If other fibres are present, those are identified using the test method of ISO/TR 11827 and removed using the relevant part of the ISO 1833 series.</p>
<p>This method is not applicable for the fibre surface that is damaged during the process (e.g. chemically or physically).</p>
