BS ISO 17257:2020

This standard BS ISO 17257:2020 Rubber. Identification of polymers. Pyrolytic gas-chromatographic method using mass-spectrometric detection is classified in these ICS categories:

• 83.060 Rubber

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 <10 %, detection and identification can be difficult.

A non-restrictive list of rubbers is given in Clause 4.
