<p>This document specifies quantitative testing methods of fibres that consist of cupro and lyocell by using infrared spectroscopy (IR) analysis and multivariate analysis. </p>
<p>This testing method is applied only for cupro or lyocell or a mix of both. The other fibres, such as cotton, viscose, etc. are identified using the test method of ISO/TR 11827 and removed using the relevant part of the ISO 1833 series.</p>
