Textiles - Determination of the content of bonds based on chlorobenzene and chlorotoluene

Title (German)

Textilien - Bestimmung des Gehaltes von Verbindungen auf der Basis von Chlorbenzol und Chlortoluol

Overview

This standard specifies a method of analysis for the determination of the chlorotoluene and chlorobenzene content in textile products and components, such as upper fabric, interlinings, laid-in fabrics, slide fasteners, buttons, labels, yarns and appliqués. The method applies to a mass fraction of 0,1 mg/kg to 10 mg/kg per single isomer. Higher and lower mass fractions can be determined if the weighed portion of the sample is selected accordingly or corresponding dilutions have been prepared during the procedure. The sample which has been cut into small pieces is extracted in an ultrasonic bath, with dichloromethane in a closed container. The extract is liberated with membrane filters from disturbing particles and fibres and analysed without additional clean-up with a gas chromatograph coupled to a mass-selective detector in selected ion mode. The Committee responsible for this standard is NA 062-05-12 AA "Textilchemische Prüfverfahren und Fasertrennung" ("Testing methods for separation and chemistry of textile fibres") at DIN.
