ISO 20163 specifies chromatographic methods for the determination of the inorganic free sulphur (Sx) not consumed during the vulcanization of the rubber. This method is used primarily to compare the free sulphur content in different samples.
Note 1: In ISO 20163, “free sulphur” is used instead of “inorganic free sulphur”.
Note 2: The residual curing agent containing sulphur is not concerned by this measure.
ISO 20163 on vulcanized rubber is relevant to:
Vulcanized rubber is any rubber that's been hardened through heat and sulphur. It's created through a curing process during which the rubber's elastomers harden in response to heat and sulphur.
ISO 20163 specifies the requirements for vulcanized rubber and helps in determining the sulphur by gas chromatography and HPLC.
ISO 20163 describes procedures and principles related to methods and reagent material requirements for standard solutions, preparing standard solutions, preparing standard calibration curves, as well as chromatography procedures for sampling and analysis of vulcanized rubber products.
Overall, ISO 20163 is a comprehensive guide to provide methods for determining free sulphur by gas chromatography, so users will gain a better understanding of the quality of vulcanized rubber and can increase the quality and durability of rubber products.
