What is BS EN 17137 - chlorobenzenes and chlorotoluenes in textile about?  
Chemicals such as chlorobenzenes and chlorotoluenes are persistent and bio-accumulative. Since they may affect the liver, thyroid, and the central nervous system, monitoring their presence in products is necessary.
BS EN 17137 specifies a method of analysis for determining the content of chlorobenzenes and chlorotoluenes in textile products made from components such as fabric, interlining, lining, plastic buttons, plastic slide fasteners, labels and threads.
BS EN 17137 specifies a method which applies to a mass fraction of 0,1mg/kg to 10mg/kg per single isomer. Both high and low concentration can be determined if the mass of the sample is selected accordingly or if appropriate dilutions are made during the analysis.
Who is BS EN 17137 - chlorobenzenes and chlorotoluenes in textiles for? 
BS EN 17137 on chlorobenzenes and chlorotoluenes in textiles is useful for: 
- Manufacturers of synthetic textile products (polyester and polyester blends)
- Manufacturers of labels and threads for textile products
- Users of dye carriers, levelling agents, dyes and auxiliaries
Why should you use BS EN 17137 - chlorobenzenes and chlorotoluenes in textile?  
Some chlorobenzenes are toxic and can be harmful for health well as the environment, which necessitates the monitoring of their levels in products. BS EN 17137 helps you to identify the levels of chlorobenzenes and chlorotoluenes in textile products.
BS EN 17137 walks you through the test procedure which includes sampling and specimen preparation, extraction, and filtration. Gas chromatographic determination and calibration have been discussed in BS EN 17137.
BS EN 17137 helps you to comply with regulations, since the presence of chlorobenzenes and chlorotoluenes in final textile products is restricted. BS EN 17137 helps you to ensure that your products are not adversely affecting users.
