Standard Test Method for Residual Vinyl Chloride Monomer in Poly(Vinyl Chloride) Resins by Gas Chromatographic Headspace Technique

Importancia y uso:

5.1 Poly(vinyl chloride) resins must contain a minimum possible amount of unreacted, or free, VCM.

5.2 This test method provides a measure of RVCM which is suitable for manufacturing control or specification acceptance purposes.

5.3 Under optimum conditions, a lower level of detection of 2 ppm by volume VCM can be detected in the headspace vapor. Using a 4-g sample, this is equivalent to about 0.02 ppm by mass RVCM in the PVC resin.
