Textiles - Quantitative chemical analysis - Part 7: Mixtures of polyamide and certain other fibres (method using formic acid) (ISO 1833-7:2017)

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 %; ISO 1833-4 applies.

Textilien - Quantitative chemische Analysen - Teil 7: Mischungen aus Polyamid- und bestimmten anderen Fasern (Ameisensäure-Verfahren) (ISO 1833-7:2017)

Dieses Dokument legt ein Ameisensäure-Verfahren fest zur Bestimmung des prozentualen Massenanteils an Polyamidfasern, nach dem Abtrennen der nichtfaserigen Begleitstoffe, in Textilien aus Mischungen aus
— Polyamid
mit
— Baumwolle, Viskose, Cupro, Modal, Lyocell, Polyester, Polypropylen, Chlorfaser, Polyacryl, Glasfaser, Elastomultiester, Elastolefin und Melamin oder
— Wolle (sofern der Gesamtgehalt an Wolle kleiner oder gleich 25 % beträgt) oder Tierhaarfasern.
Dieses Dokument ist nicht anwendbar, wenn der Gesamtgehalt an Wolle 25 % übersteigt; dann gilt ISO 1833-4.

Textiles - Analyse chimique quantitative - Partie 7: Mélanges de polyamide et de certaines autres fibres (méthode à l'acide formique) (ISO 1833-7:2017)

ISO 1833-7:2017 spécifie une méthode de détermination, à l'acide formique, de la masse, exprimée en pourcentage, de fibres de polyamide, après élimination des matières non fibreuses, dans les textiles composés de mélanges de:
-      polyamide;
avec
-       coton, viscose, cupro, modal, lyocell, polyester, polypropylène, chlorofibre, acrylique, fibre de verre, élastomultiester, élastoléfine et melamine; ou
-      laine (si la proportion de laine est inférieure ou égale à 25 %), ou autres poils animaux.
ISO 1833-7:2017 ne s'applique pas lorsque la proportion de laine dépasse 25 %; l'ISO 1833‑4 s'applique.

Tekstilije - Kvantitativna kemična analiza - 7. del: Mešanica poliamidnih in nekaterih drugih vlaken (metoda z uporabo mravljične kisline) (ISO 1833-7:2017)

Ta dokument določa metodo z uporabo mravljične kisline za ugotavljanje masnega odstotka poliamidnih vlaken po odstranitvi nevlakenske snovi v tekstilijah iz mešanic – poliamida
– z bombažem, viskozo, s kupro vlakni, z modalnimi vlakni, liocelom, s poliestrom, polipropilenom, klorovlakni, z akrilnimi vlakni, s steklenimi vlakni, z elastomultiestrom, elastolefinom in melaminom ali
– z volno (če je delež volne enak ali manjši od 25 %) ali vlakni živalskega izvora.
Ta dokument se ne uporablja, če delež volne presega 25 %. V takih primerih se uporablja standard ISO 1833-4.
