ISO 16373-3-2014 pdf free download.Textiles — Dyestuffs —Part 3: Method for determination of certain carcinogenic dyestuffs (method using triethylamine/methanol).
This part of IS0 16373 specifies a method for the detection and quantitative determination of thepresence of carcinogenic dyestuffs as listed in Table 1 in dyed, printed or coated textile products bychromatographic analysis of their extracts.
2Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1 textile
woven fabric, knitted fabric, etc., formed by the interlocking ofibres andyarns having a certain cohesionand which is generally intended for clothing or furniture applications
Note 1 to entry: Textiles often include certain types of non-woven fabrics.
2.2 carcinogenic dyestuff
substance yielding a dye that is a substance known to be or suspected of being a human carcinogen
3 Principle
The dyestuff of a coloured test specimen is extracted by means of a solvent in an ultrasonic bath underspecified conditions. The extract is analysed using either a high-performance liquid chromatographyphotodiode arraydetector(HPLC-DAD)orahigh-performanceliquid chromatography massspectrometer(HPLC-MSD).
The carcinogenic dyestuffs are listed in Table 1.
4 safety precautions
4.1 General
Warning —The dyestuffs targeted in this part of ISO 16373 are classified as substances knownto be or suspected of being human carcinogens.
4.2Handling
lt is the user’s responsibility to ensure any handling and disposal of these substances are in strictaccordance with the appropriate national health and safety regulations.
It is the user’s responsibility to use safe and proper techniques in handling materials in this testmethod.Consult manufacturers for specific details, such as materialsafety data sheets and otherrecommendations.
Good laboratory practice should be followed. Wear safety glasses in all laboratory areas andsingle-use dust respirator while handling the dyestuff powder.
