Textiles - Methods for determination of certain aromatic amines derived from azo colorants - Part 1: Detection of the use of certain azo colorants accessible with and without extracting the fibres
This European Standard 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 textile fibres and that are accessible to reducing agent with and without extraction.
Azo colorants accessible to reducing agent without extraction are those used to dye:
cellulosic fibres (e.g. cotton, viscose);
protein fibres (e.g. wool, silk);
synthetic fibres (e.g. polyamide, acrylic).
Azo colorants accessible with extraction are those used to dye man-made fibres with disperse dyes. The following man-made fibres can be dyed with disperse dyes: polyester, polyamide, acetate, triacetate, acrylic and chlorofibre.
For certain commodities made of cellulose and/or protein fibres blended with man-made fibres it is necessary to extract the dye first.
The method is relevant for all coloured textiles, e.g. dyed, printed and coated textiles.
Textilien - Verfahren für die Bestimmung bestimmter aromatischer Amine aus Azofarbstoffen - Teil 1: Nachweis der Verwendung bestimmter Azofarbstoffe mit und ohne Extraktion der Faser
Dieser Teil der EN 14362 legt ein Verfahren zum Verwendungsnachweis bestimmter Azofarbstoffe fest, die bei der Herstellung oder Behandlung bestimmter Waren aus Textilfasern nicht verwendet werden dürfen und die mit und ohne vorheriger Extraktion reduziert werden können.
Azofarbstoffe, die ohne vorherige Extraktion reduziert werden können, sind diejenigen, die verwendet werden zum Färben von:
Zellulosefasern (z. B. Baumwolle, Viskose);
Eiweißfaserstoffen (z. B. Wolle, Seide);
Synthesefasern (z. B. Polyamid, Acryl).
Azofarbstoffe, die mit vorheriger Extraktion verfügbar sind, sind diejenigen, die zum Färben von Chemiefasern mit Dispersionsfarbstoffen verwendet werden. Die folgenden Kunstfasern können mit Dispersionsfarbstoffen gefärbt werden: Polyester, Polyamid, Acetat, Triacetat, Acryl und Chlorfaser.
Bei bestimmten Waren, die aus Zellulose und/oder Eiweißfasern bestehen und mit Kunstfasern gemischt sind, ist es erforderlich, zuerst den Farbstoff zu extrahieren.
ANMERKUNG Das Verfahren gilt für alle farbigen Textilien, z. B. gefärbte, bedruckte und beschichtete Textilien.
Textiles - Méthodes de détermination de certaines amines aromatiques dérivées de colorants azoïques - Partie 1: Détection de l'utilisation de certains colorants azoïques accessibles avec ou sans extraction
La présente partie de l’EN 14362 décrit un mode opératoire permettant de détecter l’utilisation de certains colorants azoïques qui ne peuvent pas être utilisés dans la fabrication ou le traitement de certains articles en fibres textiles et qui sont accessibles aux agents de réduction avec ou sans extraction.
Les colorants azoïques accessibles aux agents de réduction sans extraction sont ceux utilisés pour teindre :
des fibres cellulosiques (par exemple, le coton, la viscose) ;
des fibres protéiques (par exemple, la laine, la soie) ;
des fibres synthétiques (par exemple, les polyamides, l’acrylique).
Les colorants azoïques accessibles avec extraction sont ceux utilisés pour teindre les fibres chimiques au moyen de colorants dispersés. Les fibres chimiques suivantes peuvent être teintes au moyen de colorants dispersés : polyester, polyamide, acétate, triacétate, acrylique et chlorofibre.
Il est nécessaire d’extraire en premier lieu le colorant pour certains articles constitués de fibres cellulosiques et/ou de fibres protéiques mélangées à des fibres chimiques.
NOTE La méthode est adaptée à tous les textiles colorés, par exemple les textiles teints, imprimés et enduits.
Tekstilije - Metode za določevanje nekaterih aromatskih aminov, izvirajočih iz azo barvil - 1. del: Zaznavanje prisotnosti določenih azo barvil, dostopnih z ekstrahiranjem vlaken in brez njega
Ta del standarda EN 14362 opisuje postopek za zaznavanje prisotnosti določenih azo barvil, ki se uporabljajo pri proizvodnji in obdelavi nekaterih izdelkov iz tekstilnih vlaken ter so reducentom dostopna z ekstrahiranjerm ali brez njega.
Azo barvila, reducentom dostopna brez ekstrahiranja, so tista barvila, ki se uporabljajo za barvanje:
celuloznih vlaken (npr. bombaž, viskoza);
proteinskih vlaken (npr. volna, svila);
sintetičnih vlaken (npr. poliestrska, poliakrilonitrilna vlakna);
Azo barvila, reducentom dostopna z ekstrahiranjerm, so tista barvila, ki se uporabljajo za barvanje kemičnih vlaken z disperznimi barvili. Kemična vlakna, ki se lahko barvajo z disperznimi barvili so naslednja: poliestrska, poliamidna, acetatna, triacetatna in poliakrilonitrilna vlakna ter klorovlakna.
Pri nekaterih izdelkih iz mešanice celuloznih in/ali proteinskih vlaken ter kemičnih vlaken je najprej potrebna ekstrakcija barvila.
OPOMBA: Metoda je primerna za vse vrste barvanega tekstila, npr. barvan, tiskan in prevlečen tekstil.

NOTE Acetonitrile is an appropriate solvent for this stock solution, resulting in good stability of amines. 6.10.2 Calibration solution of amines for daily use.
Dilute from the stock solution 6.10.1 to a concentration of ρ = 15,0 µg of each amine per millilitre of an appropriate solvent. 6.10.3 Calibration solutions of amines for quantification, concentration range from 2 µg up to 50 µg of each amine per millilitre of an appropriate solvent. NOTE It is the responsibility of each lab to choose appropriate concentrations for the calibration. 6.10.4 Internal standards in solution (IS), ρ = 1,0 mg of IS/ml of the appropriate IS solvent.
In case of GC-MS analysis, use one of the following internal standards: IS1: benzidine-d8, CAS No.: 92890-63-6; IS2: naphthalene-d8, CAS No.: 1146-65-2; IS3: 2,4,5-trichloroaniline, CAS No.: 636-30-6; IS4: anthracene-d10, CAS No.: 1719-06-8. NOTE If the confirmation analysis for benzidine is done with DAD or TLC the use of IS1: benzidine-d8, CAS No.: 92890-63-6 is not feasible, because the peak cannot be separated from the none deuterated benzidine. 6.11 Sodium hydroxide aqueous solution, a mass fraction of 10 %. 6.12 Grade 3 water, complying with EN ISO 3696:1995. 7 Apparatus 7.1 Extraction apparatus, according to Figure 1, consisting of:

NOTE "White" is not considered as "colour" and therefore "white" parts do not have to be tested. 8.6.2 Case of colour gathering Up to three colours may be tested together. In order to gather three colours, the following rules shall be applied. The rules have been listed in order of preference: Select the three colours from the same part of the textile article; SIST EN 14362-1:2012
