ISO 1833-7:2017

Textiles — Quantitative chemical analysis — Part 7: Mixtures of polyamide with certain other fibres (method using formic acid)

ISO 1833-7:2017 specifies a method, using formic acid, to determine the mass percentage of polyamide fibre, after removal of non-fibrous matter, in textiles made of mixtures of

– polyamide

with

– cotton, viscose, cupro, modal, lyocell, polyester, polypropylene, chlorofibre, acrylic, glass fibre, elastomultiester, elastolefin and melamine, or

– wool (if the wool content is less than or equal to 25 %), or animal hair fibres.

ISO 1833-7:2017 does not apply when the wool content exceeds 25 %; ISO 1833-4 applies.
