1. New EU Standard of Azo Colorants EN 14362-1:2012 and EN 14362-3:2012 has been Published
 
EN 14362-1:2012 “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” was published on 31 March 2012. It supersedes the current test standards EN 14362-1: 2003 and EN 14362-2: 2003 and has been effective on 1 September 2012. EN 14362-1:2012 describes a procedure to detect the banned aromatic amines derived from azo colorants in textile fibres, including natural, man-made, regenerated and blended fibres. The standard is relevant for all coloured textiles, e.g. dyed, printed and coated textiles.
 
Highlights of the New Standard EN 14362-1:2012:
ü   All the parts of the textile article that have direct and prolonged contact to skin or mouth have to be analyzed
ü   “White” is not considered a color and therefore, white items do not have to be analyzed
ü   Composite testing is allowed for up to 3 colors
ü   Special instructions in case of very small samples:
·         If the mass of a part is < 1 g, multiple parts of the same kind can be tested together as one material
·         If the total mass of a material is < 0.2 g, testing of that material is not required
ü   Method for extracting colorants is based on the textile composition
ü   Additional method for the identification of amines from colorants is provided
ü   Optional screening method included
 
EN 14362-3:2012 “Textiles - Methods for determination of certain aromatic amines derived from azo colorants. Detection of the use of certain azo colorants, which may release 4-aminoazobenzene” was published on 31 July 2012 and will be effective on 31 December 2012.
 
Azo colorants that are able to form 4-aminoazobenzene, generate under the conditions of EN 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. Part 3 of EN 14362 is supplementary to Part 1 and describes a special procedure to detect the use of certain azo colorants in commodities, which may release 4-aminoazobenzene.
 
 
歐盟公佈偶氮染料新標準EN 14362-1:2012EN 14362-3:2012
 
歐洲標準委員會已於2012331日公佈新標準EN 14362-1:2012「紡織品從偶氮染料中釋出的某些芳香胺的測定方法 - 第一部分: 檢測未經抽出纖維或抽出纖維後可接觸到的某些偶氮染料」。新標準已於201291日正式生效,並取代現行標準 EN 14362-1:2003EN 14362-2:2003EN 14362-1:2012是檢測紡織纖維中偶氮染料釋出被禁芳香胺的測定方法,包括天然、人造、再生及混紡纖維。此標準覆蓋所有有顏色的紡織品,例如:染色、印刷及塗層的紡織品。
 
新標準EN 14362-1:2012的主要重點:
ü   與人體皮膚或口腔有直接或長期直接接觸的紡織品必須進行測試
ü   「白色」不會被當作顏色,因此白色類別的項目不需要進行測試分析
ü   複合測試可容許最多3種顏色
ü   細小部份的特別指令
·         如細小部份的重量少於1, 同類的部件可當作同一種物料進行測試
·         如該物料的總重量少於0.2克,該物料不需要進行
ü   染料提取的方法是根據紡織品的成份
ü   提供識別染料中的芳香胺的其他方法
ü   包括選擇性的篩檢方法
 
新標準EN 14362-3:2012「紡織品從偶氮染料中釋出的某些芳香胺的測定方法 - 第三部分: 檢測可釋出4-氨基偶氮苯的某些偶氮染料」已於2012731日公佈,並將於20121231日正式生效
 
可形成4-氨基偶氮苯的偶氮染料在EN 14362-1檢測方法的還原條件下,會繼續裂解成苯胺及1,4 - 苯二胺,但在沒有其他輔助資訊 (例如所用染料的化學結構等)或其他特別程序下,不能判斷是否含有4-氨基偶氮苯。EN 143623部份是補充第1部份的標準,是用來檢測產品中可能釋放4 - 氨基偶氮苯的某些偶氮染料的特定方法。
