DANSK DSF/PREN ISO 1833-13 PDF

This part of ISO 1833 specifies a method, using carbon disulfide/acetone, to determine the mass percentage of chlorofibre, after removal of non-fibrous matter, in textiles made of mixtures of certain chlorofibres, with – wool, animal hair, silk, cotton, viscose, cupro, modal, lyocell, polyamide, polyester, elastomultiester, acrylic, melamine, polypropylene, polypropylene/polyamide bicomponent, polyacrylate and glass fibres. Before carrying out the analysis, the solubility of the chlorofibres in the reagent shall be checked. When the wool or silk content of a mixture exceeds 25 %, the method described in ISO 1833-4 shall be used. When the polyamide content of a mixture exceeds 25 %, the method described in ISO 1833-7 shall be used. It is also possible to analyse mixtures containing chlorofibres by using the test methods described in ISO 1833-13 or ISO 1833-21.
