This International Standard specifies a method for the determination of residual vinyl chloride monomer in homopolymer and copolymer resins of vinyl chloride.
For the purpose of this International Standard, the field of application is limited to these homopolymer and copolymer resins, but the method is also applicable to materials and articles made from the resins.
The lower limit of detection is dependent on the extent to which impurities in the solvent interfere. Use of the solvent specified ensures that 0,5 mg/kg can be detected but 0,2 mg/kg can be detected if interference is sufficiently low.
