Azo Dyes: European Standard EN 14362 for Detection of Banned Aromatic Amines Has Been RevisedThe European Committee for Standardization (CEN) has revised the test methods for the detection of certain aromatic amines derived from azo colorants, EN 14362 Part 1 and Part 2. Part 1 and 2 are combined in the revised standard. Guidance regarding samples and which test to apply as well as minor changes in the extraction process is also included in the revision. The new standard, EN 14362-1:2012, will be effective in August 2012.
