DIN EN ISO 16373-1
Textiles - Dyestuffs - Part 1: General principles of testing coloured textiles for dyestuff identification (ISO 16373-1:2015); German version EN ISO 16373-1:2015

Title (German)

Textilien - Farbstoffe - Teil 1: Allgemeine Grundlagen der Prüfung farbiger Textilien zur Farbstoff-Identifikation (ISO 16373-1:2015); Deutsche Fassung EN ISO 16373-1:2015

Overview

This part of ISO 16373 gives the definition of the colourant classes and the relationship to textile fibres. It describes some procedures to identify qualitatively the colourant class used in textile material. This document has been prepared by Technical Committee CEN/TC 248 "Textile and textile products", the secretariat of which is held by BSI (United Kingdom), in collaboration with Technical Committee ISO/TC 38 "Textiles". The ISO 16373 series deals with dyes used in textiles for qualification and quantification. This part of ISO 16373 includes the definition of the classes of dyes, the description of some procedures to identify qualitatively the class of dyes used in textile material. The other parts of ISO 16373 are related to the quantification of some dyes. - The principle of the test method in ISO 16373-2 is based on the extraction using pyridine-water solution, which has been found to be the most efficient solution to extract a large range of dyes, including allergenic and carcinogenic dyes. - The principle of the test method in ISO 16373-3 is based on the extraction using triethylaminemethanol solution. This solution has been found efficient to extract some dyes in some cases. Additional information related to the recovery rates (to characterize the extraction efficiency) obtained from the application of ISO 16373-2 and ISO 16373-3 are summarized in Annex B. It is important to note that there are other test methods related to azo dyes, for which a reduction of the extracted azo dyes leads to the release of some aromatic amines to be detected and determined using chromatography (See Bibliography/Aromatic amines determination).
