Textiles - Methods for determination of certain aromatic amines derived from azo colorants - Part 3: Detection of the use of certain azo colorants, which may release 4-aminoazobenzene (ISO 14362-3:2017)
Azo colorants that are able to form 4-aminoazobenzene, generate under the conditions of ISO 14362-1, the amines aniline and 1,4-phenylenediamine. The presence of these 4-aminoazobenzene colorants cannot be reliably ascertained without additional information (e.g. the chemical structure of the colorant used) or without a special procedure.
ISO 14362-3:2017 is supplementary to ISO 14362-1 and describes a special procedure to detect the use, in commodities, of certain azo colorants, which may release 4-aminoazobenzene, and that are
- accessible to reducing agent without extraction, particularly concerning textiles made of cellulose and protein fibres (e.g. cotton, viscose, wool, silk), and
- accessible by extracting the fibres (e.g. polyester or imitation leather).
For certain fibre blends, in 9.3 and 9.4 (with and without extraction) may need to be applied.
The procedure also detects 4-aminoazobenzene (Solvent Yellow 1), which is already available as free amine in commodities without reducing pre-treatment.
The use of certain azo colorants, which may release, by reductive cleavage of their azo group(s), one or more of the other aromatic amines listed in the Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) as regards Annex XVII, except 4-aminoazobenzene, cannot be determined quantitatively with this method.

Textiles - Méthodes de détermination de certaines amines aromatiques dérivées de colorants azoïques - Partie 3: Détection de l'utilisation de certains colorants azoïques susceptibles de libérer du 4-aminoazobenzène (ISO 14362-3:2017)
Les colorants azoïques capables de former du 4-aminoazobenzène génèrent, dans les conditions de l'ISO 14362‑1, des amines dont l'aniline et la 1,4-phénylènediamine. La présence de ces matières colorantes à base de 4-aminoazobenzène ne peut pas être déterminée de façon fiable sans informations supplémentaires (par exemple sur la structure chimique de la matière colorante colorant utilisé) ou sans mode opératoire spécifique.
ISO 14362-3:2017 est un complément à l'ISO 14362‑1 et décrit un mode opératoire spécifique permettant de détecter, dans des articles, l'utilisation de certains colorants azoïques pouvant libérer du 4-aminoazobenzène:
- accessibles aux agents de réduction sans extraction, en particulier dans le cas des textiles fabriqués à partir de fibres de cellulose et de fibres animales (par exemple le coton, la viscose, la laine, la soie); et
- accessibles par extraction des fibres (par exemple le polyester ou l'imitation du cuir).
Pour certains mélanges de fibres, il peut être nécessaire d'appliquer 9.3 et 9.4 (avec et sans extraction).
Le mode opératoire détecte également le 4-aminoazobenzène utilisé en tant que colorant (Solvent Yellow 1) qui est déjà disponible dans des articles sous la forme de l'amine libre, sans dégradation par traitement de réduction.
L'utilisation de certains colorants azoïques, qui peuvent libérer par clivage réducteur de leur(s) groupe(s) azoïque(s) une ou plusieurs des autres amines aromatiques répertoriées dans le Règlement CE n° 1907/2006 du Parlement européen et du Conseil concernant l'enregistrement, l'évaluation et l'autorisation des substances chimiques, ainsi que les restrictions applicables à ces substances (REACH) conformément à l'Annexe XVII, exception faite du 4-aminoazobenzène, ne peut pas être déterminée quantitativement avec cette méthode.
Tekstilije - Metode za določevanje nekaterih aromatskih aminov, izvirajočih iz azo barvil - 3. del: Zaznavanje prisotnosti določenih azo barvil, ki lahko sproščajo 4-aminoazobenzen (ISO 14362-3:2017)
Iz azo barvil, ki lahko tvorijo 4-aminoazobenzen, pod pogoji iz standarda ISO 14362-1 nastaneta amina anilin in 1,4-fenilenediamin. Prisotnosti teh barvil iz 4-aminoazobenzena ni mogoče zanesljivo ugotoviti brez dodatnih informacij (npr. kemijske strukture uporabljenega barvila) ali posebnega postopka.
Ta dokument dopolnjuje standard ISO 14362-1 in opisuje poseben postopek za zaznavanje prisotnosti (pri izdelkih) nekaterih azo barvil, ki lahko sproščajo 4-aminoazobenzen in so:
– reducentom dostopna brez ekstrahiranja, zlasti pri tekstilijah iz celuloznih in proteinskih vlaken (npr. bombaž, viskoza, volna, svila); ter
– dostopna z ekstrakcijo vlaken (npr. poliester ali umetno usnje).
Za nekatere mešanice vlaken (z ekstrahiranjem ali brez njega) bo morda treba uporabiti točki 9.3 in 9.4.
Postopek omogoča tudi zaznavanje 4-aminoazobenzena (Solvent Yellow 1 – topilo rumena 1), ki je v izdelkih že razpoložljiv kot prosti amin brez predhodne obdelave z redukcijo.
Kvantitativno določevanje uporabe določenih azo barvil, ki lahko z redukcijsko cepitvijo svojih azo skupin sproščajo enega ali več drugih aromatskih aminov iz Priloge XVII k Uredbi (ES) št. 1907/2006 Evropskega parlamenta in Sveta o registraciji, evalvaciji, avtorizaciji in omejevanju kemikalij (REACH), razen 4-aminoazobenzena, s to metodo ni mogoče.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
