Defines 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.

This document 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.
This document does not apply when the wool content exceeds 25%; ISO1833‑4 applies.
