EN ISO 1833-21:2010 Textiles - Quantitative chemical analysis - Part 21: Mixtures of chlorofibres, certain modacrylics, certain elastanes, acetates, triacetates and certain other fibres (method using cyclohexanone) (ISO 1833-21:2006)
This part of ISO 1833 specifies a method, using cyclohexanone, to determine the percentage of chlorofibre,modacrylic, elastane, acetate and triacetate, after removal of non-fibrous matter, in textiles made of binary mixtures of? acetate, triacetate, chlorofibre, certain modacrylics, certain elastanes and? wool, animal hair, silk, cotton, cupro, modal, viscose, polyamide, acrylic and glass fibre.Where modacrylics or elastanes are present, a preliminary test should be carried out to determine whether the fibre is completely soluble in the reagent.It is also possible to analyse mixtures containing chlorofibres by using the test methods described in ISO 1833-13
