This document specifies the qualitative analysis for cupro and lyocell using the two methods separately<\/p>\n

    \n
  1. \n

    scanning electron microscope (SEM) method based on the application of ISO 20705<\/span><\/span> , and<\/p>\n<\/li>\n

  2. \n

    spectral analysis method.<\/p>\n<\/li>\n<\/ol>\n

    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<\/span><\/span> and removed using the relevant part of the ISO 1833 series<\/span><\/span>.<\/p>\n

    This method is not applicable for the fibre surface that is damaged during the process (e.g. chemically or physically).<\/p>\n
