Recently, the Analysis and Testing Center of China Blue Morning Light Institute took the lead in developing the international standard ISO 1158:2026 \"Plastics – Vinyl chloride homopolymers and copolymers – Determination of chlorine content\", which has now been officially released. Chlorine content is a key parameter that determines the properties, grades, and applicability of PVC resin and its copolymers. The new chlorine content testing standard for fuels? Burn? The bottle method has been revised, significantly improving the accuracy of chlorine content determination as well as the safety of the testing process, thereby providing laboratories with a more reliable and safer basis for testing. The implementation of this standard provides a unified and authoritative measurement benchmark for numerous downstream industries, which will effectively contribute to the high-quality and standardized development of the polymer materials industry.
