Textiles - Quantitative chemical analysis - Part 17: Mixtures of cellulose fibres and certain fibres with chlorofibres and certain other fibres (method using concentrated sulfuric acid) (ISO 1833-17:2019)

This document specifies a method, using concentrated sulfuric acid, to determine the mass percentage of chlorofibres and certain other fibres, after removal of non-fibrous material, in textiles made of mixtures of
— cotton, viscose, cupro, modal, lyocell, acetate, triacetate, polyamide, polyester, elastomultiester, certain acrylic and certain modacrylic fibres
with
— chlorofibres (based on homopolymers of vinyl chloride), polypropylene, elastolefin, melamine and polypropylene/polyamide bicomponent.
The modacrylics concerned are those which give a clear solution when immersed in concentrated sulfuric acid.
This method can be used, particularly in place of the methods described in ISO 1833-12 and ISO 1833-13, in all cases where a preliminary test shows that the chlorofibres do not dissolve completely either in dimethylformamide or in the azeotropic mixture of carbon disulfide and acetone.

Textilien - Quantitative chemische Analysen - Teil 17: Mischungen aus Cellulosefasern und bestimmten Fasern mit Chlorfasern und bestimmten anderen Fasern (Verfahren mit konzentrierter Schwefelsäure) (ISO 1833-17:2019)

Dieses Dokument legt ein Verfahren fest, bei dem konzentrierte Schwefelsäure verwendet wird, zur Bestimmung des prozentualen Massenanteils an Chlorfasern und bestimmten anderen Fasern, nach dem Abtrennen der nichtfaserigen Begleitstoffe, in Textilien aus Mischungen aus:
- Baumwolle, Viskose, Cupro, Modal, Lyocell, Acetat, Triacetat, Polyamid, Polyester, Elastomultiester, bestimmten Polyacryl- und bestimmten Modacrylfasern
mit
- Chlorfasern (auf Basis von Homopolymeren des Vinylchlorids), Polypropylen, Elastolefin, Melamin und Polypropylen-/Polyamid-Bikomponentenfasern.
Bei den betroffenen Modacrylfasern handelt es sich um solche, die beim Eintauchen in konzentrierte Schwefelsäure eine klare Lösung ergeben.
Dieses Verfahren kann insbesondere anstelle der in ISO 1833 12 und ISO 1833 13 beschriebenen Verfahren in allen Fällen angewendet werden, in denen Vorprüfungen zeigen, dass sich die Chlorfasern weder in Dimethylformamid noch in der azeotropen Mischung aus Schwefelkohlenstoff und Aceton vollständig auflösen.

Textiles - Analyse chimique quantitative - Partie 17: Mélanges de fibres de cellulose et certaines fibres avec des chlorofibres et certaines autres fibres (méthode à l'acide sulfurique concentré) (ISO 1833-17:2019)

Le présent document spécifie une méthode de détermination, à l'acide sulfurique concentré, de la masse exprimée en pourcentage de chlorofibres et de certaines autres fibres, après élimination des matières non fibreuses, dans les textiles composés de mélanges de:
— coton, viscose, cupro, modal, lyocell, acétate, triacétate, polyamide, polyester, élastomultiester, certaines fibres acryliques et certaines fibres modacryliques;
avec
— chlorofibres (basées sur des homopolymères de chlorure de vinyle), polypropylène, élastoléfine, mélamine et bicomposant polypropylène/polyamide.
Les modacryliques concernés sont ceux qui donnent une solution claire par immersion dans de l'acide sulfurique concentré.
Cette méthode peut être utilisée, notamment à la place des méthodes décrites dans l'ISO 1833-12 et l'ISO 1833-13, dans tous les cas où un essai préliminaire a montré que les chlorofibres ne se dissolvent complètement ni dans du diméthylformamide ni dans un mélange azéotrope de sulfure de carbone et d'acétone.
