Determination of residual vinyl chloride monomer. Gas-chromatographic method.

Test methods

The residual monomer is extracted by immersion in an organic solvent and heating in a headspace vial. The gaseous phase is injected and the chromatography of the gases is analysed.

Products to test

Plastics piping systems for civil works for water in:

  • Water and sewage conveyance for buried and above-ground under pressure - unplasticized poly (vinyl chloride) (PVC-U) EN ISO 1452-1, -2, -3, -5.
  • Water supply of buried and above ground drainage, sewerage and irrigation water under pressure - Oriented unplasticized poly(vinyl chloride) (PVC-O) UNE EN 17176-2, -5 / UNE-CEN/TS 17176-3.
