Rubber - Identification of polymers - Pyrolytic gas-chromatographic method using mass-spectrometric detection
ISO 17257:2013 provides a qualitative method for the identification of rubbers by their pyrolysis products using tandem the 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.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
