Description / Abstract: This document specifies quantitative testing methods of fibres that consist of cupro and lyocell by using infrared spectroscopy (IR) analysis and multivariate analysis. 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.
