1. NewEU Standard of Azo Colorants EN 14362-1:2012 and EN 14362-3:2012has been Published  

EN14362-1:2012 “Textiles - Methods for determination of certainaromatic amines derived from azo colorants - Part 1: Detection ofthe use of certain azo colorants accessible with and withoutextracting the fibres” was published on 31 March 2012.It supersedes the current test standards EN 14362-1: 2003 and EN14362-2: 2003 and has been effective on 1September 2012. EN 14362-1:2012 describes aprocedure to detect the banned aromatic amines derived from azocolorants in textile fibres, including natural, man-made,regenerated and blended fibres. The standard is relevant for allcoloured textiles, e.g. dyed, printed and coatedtextiles. 

Highlights of the New StandardEN 14362-1:2012: 

ü  All the parts ofthe textile article that have direct and prolonged contact to skinor mouth have to be analyzed  

ü  “White” is notconsidered a color and therefore, white items do not have to beanalyzed  

ü  Composite testingis allowed for up to 3 colors 

ü  Specialinstructions in case of very small samples:  

·        If the mass of apart is < 1 g, mtiple parts of the same kind can be testedtogether as one material  

·        If the total massof a material is < 0.2 g, testing of that material is notrequired 

ü  Method forextracting colorants is based on the textilecomposition 

ü  Additional methodfor the identification of amines from colorants isprovided 

ü  Optional screeningmethod included 

EN14362-3:2012 “Textiles - Methods for determination of certainaromatic amines derived from azo colorants. Detection of the use ofcertain azo colorants, which may release4-aminoazobenzene” was published on 31 Jy 2012and will be effective on 31December 2012. 

Azo colorantsthat are able to form 4-aminoazobenzene, generate under theconditions of EN 14362-1 the amines aniline and1,4-phenylenediamine. The presence of these 4-aminoazobenzenecolorants cannot be reliably ascertained without additionalinformation (e.g. the chemical structure of the colorant used) orwithout a special procedure. Part 3 of EN 14362 is supplementary toPart 1 and describes a special procedure to detect the use ofcertain azo colorants in commodities, which may release4-aminoazobenzene. 

歐盟公佈偶氮染料新標準EN14362-1:2012及EN14362-3:2012 

歐洲標準委員會已於2012年3月31日公佈新標準EN14362-1:2012「紡織品–從偶氮染料中釋出的某些芳香胺的測定方法-**部分:檢測未經(jīng)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2012年9月1日正式生效，並取代現(xiàn)行標準EN14362-1:2003及EN14362-2:2003。EN14362-1:2012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EN14362-1:2012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*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克, 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(jù)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EN14362-3:2012「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2012年7月31日公佈，並將於2012年12月31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(xù)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(xué)結(jié)構(gòu)等)或其他特別程序下，不能判斷是否含有4－氨基偶氮苯。EN14362第3部份是補充第1部份的標準，是用來檢測產(chǎn)品中可能釋放4- 氨基偶氮苯的某些偶氮染料的特定方法。
