偶氮是國際環保要求的必檢項目之一,檢驗方法有以下兩種:氣相色譜及質譜聯用法(GC-MSD)及高效液相色譜法(HPLC)。標準規定被檢產品中不得含有24種偶氮染料中間體,若檢出其中一種即為不合格產品,其限量為要求如下:
GB 18401-2010中可分解致*芳香胺染料:禁用(限量值≤20mg/kg);
GB 20400-2006中規定可分解有害芳香胺染料:(限量值≤30mg/kg);
REACH(Registration,Evaluation, Authorization and Restriction of Chemicals)Annex 17 entry 43中規定:禁用(限量值≤30mg/kg);
Oeko-Tex Standard 100 Appendix 4 中規定: not used(限量值≤20mg/kg)
日本勞動衛生福利部(MHLW)通過修訂“家用產品有害物質管控法案”,將24種偶氮染料列為有害污染物,并進行管控。(限量值≤30mg/kg)。
涉及測試標準:
ISO 14362-1;
ISO 14362-3;
ISO17234-1/2
EN14362-1/3;
EN14362-3
LFGB §64 BVLB 82.02-15:2017
JIS L 1940-1/3:2019
GB/T19942
GB/T 17592
GB/T 23344等等
Azo is one of the required test items for international environmental protection requirements, and there are two test methods: gas chromatography and mass spectrometry (GC-MSD) and high performance liquid chromatography (HPLC). The standard stipulates that the tested product shall not contain 24 kinds of azo dye intermediates, if one of them is detected as unqualified product, its limit is as follows:
Decomposed carcinogenic aromatic amine dyes in GB 18401-2010: prohibited (limited value ≤20mg/kg);
According to GB 20400-2006, harmful aromatic amine dyes can be decomposed: (limited value ≤30mg/kg);
As specified in REACH(Registration, Evaluation, Authorization and Restriction of Chemicals)Annex 17 entry 43: Prohibited (limited value ≤30mg/kg).
As stipulated in Oeko-Tex Standard 100 Appendix 4: not used (limited value ≤20mg/kg)
The Ministry of Labor, Health and Welfare of Japan (MHLW) has revised the "Household Products Harmful Substances Control Act" to list 24 azo dyes as harmful pollutants and control them. (Limited value ≤30mg/kg).
