However, even touching these products is objectionable.

In order to determine the amount of banned azo dyes in domestic and foreign accreditation organizations, in the laboratories accredited under TS EN ISO / IEC 17025 General Conditions for the Qualification of Testing and Calibration Laboratories, in chemical and ecological field, in synthetic products except cotton and polyester, analyzes are performed. These studies are based on the following standards:

• TS EN 14362-1 Textile - Methods for the determination of certain aromatic amines derived from azo dyes - Part 1: Determination of the use of certain azo dyes which can be obtained by extraction and without making fibers.
• DIN 54231 Textile - Detection of dispersive dyes (Carcinogenic dyes)
• 35 LMBG 82.02-2, -4 Determination of the use of certain azo dyes in textile consumer goods
