Textiles — Quantitative chemical analysis — Part 4: Mixtures of certain protein fibres with certain other fibres (method using hypochlorite)

This document specifies a method, using hypochlorite, to determine the mass percentage of protein fibre, after removal of non-fibrous matter, in textiles made of mixtures of certain non-protein fibres and certain protein fibres, as follows: — wool, other animal-hair (such as cashmere, mohair), silk, protein, with — cotton, cupro, viscose, modal, acrylic, chlorofibres, polyamide, polyester, polypropylene, glass, elastane, elastomultiester, elastolefin, melamine and polypropylene/polyamide bicomponent.

Textiles — Analyse chimique quantitative — Partie 4: Mélanges de certaines fibres protéiniques avec certaines autres fibres (méthode à l'hypochlorite)

Le présent document spécifie une méthode de détermination, à l’hypochlorite, de la masse exprimée en pourcentage de fibres protéiniques, après élimination des matières non fibreuses, dans les textiles composés de mélanges de certaines fibres non protéiniques et de certaines fibres protéiniques, comme suit: — laine, autres poils animaux (par exemple cachemire, mohair), soie, protéines; avec — coton, cupro, viscose, modal, acrylique, chlorofibres, polyamide, polyester, polypropylène, verre textile, élasthanne, élastomultiester, élastoléfine, mélamine et bicomposant polypropylène/polyamide.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
