Annotation of standard text ČSN EN ISO 20596-2 (757560):

This document specifies a method for the determination of certain cyclic volatile methylsiloxanes (cVMS) in environmental water samples with low density polyethylene (LDPE) as a preservative and subsequent liquid-liquid extraction with hexane containing 13C-labeled cVMS as internal standards. The extract is then analysed by gas chromatography-mass spectrometry (GC-MS). This document is applicable to the measurement of the following cVMS in rivers, streams, and waste water (influent and effluent)
