ActiveDetermination of compounds and products based on vingl chloride homopolymers and copolymers to evolve hydrogen chloride and any other acidic products at elevoted temperatures--Congo red method
以氯乙烯均聚和共聚物为主的共混物及制品在高温时放出氯化氢和任何其他酸性产物的测定 刚果红法
Application Summary AI generated
This standard specifies the Congo red method for determining the thermal stability of PVC-based materials by measuring the time required for them to release hydrogen chloride and other acidic gases at elevated temperatures. It is applied in quality control and material testing for PVC compounds, pipes, cables, and other plastic products to assess their resistance to thermal degradation during processing or end-use.
