Описание (английский):

This document 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 0,1 mg/kg to 3,0 mg/kg can be determined.

Overview

EN ISO 6401:2022 - Plastics - Poly(vinyl chloride) - Determination of residual vinyl chloride monomer using gas‑chromatographic method - defines a standardized laboratory procedure to measure residual vinyl chloride monomer (VCM) in PVC homopolymers, copolymers and compounded materials. The method uses sample dissolution (or swelling) in N,N'‑dimethylacetamide (DMAc) and headspace gas chromatography (HS‑GC) to quantify VCM in the range 0.1 mg/kg to 3.0 mg/kg. The document supersedes the 2008 edition and was adopted by CEN as EN ISO 6401:2022.

Key topics and technical requirements

Principle: quantification of VCM by headspace sampling of polymer dissolved or swollen in DMAc followed by GC analysis.

Scope: applicable to homopolymers, copolymers of vinyl chloride and compounded PVC materials.

Detection limits and range: method limits permit determination from 0.1 mg/kg up to 3.0 mg/kg VCM.

Apparatus and reagents: automatic static headspace sampler, suitable GC column and detector, high‑purity gases, gastight syringes, and glass vials with PTFE‑lined septa. DMAc is specified as the solvent (standard provides density reference).

Standards for calibration: preparation of primary and working vinyl chloride calibrants, storage conditions (cool storage recommended) and construction of a calibration graph for quantification.

Sampling and sample handling: advice to cool samples before sampling (to reduce monomer loss), avoid humidity condensation, seal samples in completely filled glass bottles/vials, and process quickly to minimize VCM volatility.

Safety: explicit warnings that vinyl chloride and DMAc are hazardous - work must be conducted in well‑ventilated fume hoods with appropriate lab safety practices.

Annexes: includes guidance on suitable GC columns and typical calibration responses; test report content and method precision are also specified.

Applications and practical value

Routine quality control testing in PVC production and compounding to ensure residual VCM meets safety and regulatory limits.

Material certification for suppliers and purchasers of PVC resins and compounded products.

Regulatory compliance and risk assessment related to worker and consumer exposure to vinyl chloride.

For method validation, inter‑laboratory comparisons and establishing supplier specifications.
