Textiles - Methods for determination of certain aromatic amines derived from azo colorants - Part 2: Detection of the use of certain azo colorants accessible by extracting the fibres

This part of prEN 14362 describes a procedure to detect the use of certain azo colorants that may not be used in the manufacture or treatment of certain commodities made of synthetic fibres dyed with extractable dyes.
For the direct test method, see prEN 14362-1 Detection of the use of certain azo colorants accessible without extraction.
For certain fibre blends both parts of this standard may need to be applied.

Textilien - Verfahren für die Bestimmung bestimmter aromatischer Amine aus Azofarbstoffen - Teil 2: Verwendungsnachweis bestimmter Azofarbstoffe durch Extraktion der Fasern

Dieser Teil der prEN 14362 legt ein Verfahren zum Verwendungsnachweis bestimmter Azofarbstoffe fest, die bei der Herstellung oder Behandlung bestimmter Waren aus synthetischen Fasern, die mit extrahierbaren Farbstoffen gefärbt sind, nicht verwendet werden dürfen.
Hinsichtlich des direkten Prüfverfahrens, siehe prEN 14362-1 Verwendungsnachweis bestimmter Azofarb-stoffe ohne vorherige Extraktion.
Bei bestimmten Fasermischungen kann es erforderlich sein, beide Teile dieser Norm anzuwenden.

Textiles - Méthodes de détermination de certaines amines aromatiques dérivées de colorants azoïques - Partie 2: Détection de l'utilisation de certains colorants azoïques accessibles par l'extraction des fibres

La présente partie du prEN 14362 décrit un mode opératoire permettant de détecter l'utilisation de certains colorants azoïques qui ne peuvent être utilisés dans la fabrication ou le traitement de certains articles en fibres synthétiques colorées avec des colorants extractibles.
Pour la méthode d'essai direct, voir la Partie 1 de ce prEN 14362:2001 : Essais effectués directement sur des textiles colorés - Détection de l'utilisation de certains colorants azoïques accessibles à des agents réducteurs sans extraction.

The presence of these colorants cannot be reliably ascertained withoutadditional information, e.g. the chemical structure of the colorant used.4 PrincipleThe colorant is extracted (see Figure 1) from the fibre in the headspace using appropriate solvents under reflux, forexample for polyester fibres use chlorobenzene. The extract is concentrated, transferred with methanol, taken up inaqueous citrate-buffer solution and treated in an ultrasonic bath for dispersion of the colorant.The amines formed by adding sodium dithionite are transferred to a t-butyl methyl ether phase by means of liquid-liquid extraction using diatomaceous earth columns. The extract is concentrated, and the residue is taken up inmethanol or a solvent appropriate for detection and determination of the amines using chromatography.If the amines are detected by one chromatographic method, then confirmation shall be made using one or morealternative methods.SIST EN 14362-2:2003
