What is ISO 7270‑1 about?
The ISO 7270 series discusses the analysis of rubber by the pyrolytic gas-chromatographic method. ISO 7270‑1 specifies a method for the identification of polymers, or blends of polymers, in raw rubbers and in vulcanized or unvulcanised compounds from pyrograms (pyrolysis-gas chromatographic patterns) obtained under the same conditions. This allows qualitative identification of single rubbers or blends.
The method applies first and foremost to single polymers. When the pyrogram indicates a characteristic hydrocarbon, the method is also applicable to blends. The method can be also applicable to other types of polymers when verified by the analyst in each particular case.
Note: ISO 7270‑1 is not intended for quantitative analysis.
Who is ISO 7270‑1 for?
ISO 7270‑1 on the identification of rubber polymers is applicable to all types of rubber industry, specific users of ISO 7270‑1 could be:
- Research and development teams
- Analytical laboratories
- Quality control personnel
Why should you use ISO 7270‑1?
Polymer identification is necessary to verify if the correct rubber polymer has been used in the appropriate quantity. It also helps to identify if there are any contaminants in the blends. There are a few methods to identify polymers.
ISO 7270-1 provides you with the pyrolytic gas-chromatographic method. ISO 7270-1 provides you with a detailed account of the test requirements and guide you through the step-by-step process of performing the pyrolytic gas-chromatographic method.
With the method described in ISO 7270-1, you can verify the polymer content in your products and maintain or improve their quality.
What’s changed since the last update?
BS ISO 7270‑1:2020 replaces ISO 7270‑1:2003, of which it constitutes a minor revision. It also incorporates the Amendment ISO 7270‑1:2003/Amd.1:2010.The main change in BS ISO 7270‑1:2020 compared to ISO 7270‑1:2003 is that the normative references have been updated in Clause 2.
