ASTM D3749 Vinyl Chloride Monomer determination in PVC by Gas Chromatographic Headspace technique
ASTM D3749 test method determines the residual vinyl chloride monomer content of PVC resins, with the range for this test being 0.1 to 400 ppm residual vinyl chloride monomer (RVCM). With the application of Henry’s Law constant, RVCM in a copolymer PVC resin can be determined. It is an alternate method to determine the vinyl chloride monomers in dry resin samples. The final results of this test method are displayed in SI Units.
