— certain elastane fibres
— cotton, viscose, cupro, modal, lyocell, polyamide, polyester or wool fibres.
This method is not applicable when acrylic fibres are present.
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.
When the standard is harmonized under a directive or regulation, the word Harmonized appear. When such an inscription does not appear, it means that the standard is related to / supporting the relevant directive or regulation.
