This document provides a qualitative method for the identification of rubbers by their pyrolysis products using tandem gas-chromatography/mass spectrometry. The method applies to rubbers in the raw state and to unvulcanized and vulcanized compounds. Compounds can be based on a single rubber or a blend of two or more rubbers. Where the level of a particular rubber in a blend is A non-restrictive list of rubbers is given in Clause 4.
Abstract
Overview
ISO 17257:2020 specifies a qualitative pyrolytic gas‑chromatographic method with mass‑spectrometric detection (pyrolysis‑GC/MS) for the identification of rubber polymers. The method is applicable to raw rubbers, unvulcanized and vulcanized compounds, and to compounds based on single rubbers or blends. Results are obtained by solvent extraction, controlled pyrolysis of the polymer, separation by gas chromatography and interpretation of mass spectra of characteristic pyrolysis products.
Keywords: ISO 17257:2020, pyrolytic gas chromatographic method, GC‑MS, rubber identification, pyrolysis.
Key topics and requirements
- Scope and purpose: A qualitative identification technique for polymer type determination; NOT a quantitative assay.
- Sample types: Raw rubber, unvulcanized and vulcanized compounds, and blends (note: detection and identification of a polymer present at
