适用范围：SAFETY PRECAUTIONS — Persons using this document should be familiar with normal laboratorypractice, if applicable. This document does not purport to address all of the safety concerns, if any,associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory requirements.This International Standard specifies a method for the determination of vinyl chloride monomer in homopolymer and copolymer resins of vinyl chloride and compounded materials. The method is based on sample dissolution and headspace gas chromatography. Concentrations of vinyl chloride in the range to canbe determined.A “dry method”, suitable for PVC resins but not compounded materials, is widely used within the industry for in-house determinations. A separate International Standard based on this methodology is under development.
