Tekstile - Analizat kimike sasiore - Pjesa 7: Përzjerjet e fibrave poliamide me disa fibra të tjera (metoda me acid formik) (ISO 1833-7:2006)

Textiles - Quantitative chemical analysis - Part 7: Mixtures of polyamide and certain other fibres (method using formic acid) (ISO 1833-7:2006)

Scope

ISO 1833-7:2006 specifies a method, using formic acid, to determine the percentage of polyamide fibre, after removal of non-fibrous matter, in textiles made of binary mixtures of polyamide and cotton, viscose, cupro, modal, polyester, polypropylene, chlorofibre, acrylic or glass fibre.
It is also applicable to mixtures with wool and animal hair, but when the wool content exceeds 25 %, the method described in ISO 1833-4 should be used.
