ActivePlastics - Poly(vinyl chloride) resins - Determination of number of impurities and foreign particles
塑料 聚氯乙烯树脂 杂质与外来粒子数的测定
Application Summary AI generated
This standard specifies a method for determining the number of impurities and foreign particles in poly(vinyl chloride) (PVC) resins. It is applied in the plastics industry for quality control of PVC raw materials, ensuring the resin's purity before use in manufacturing products like pipes, profiles, or films. The test involves visual inspection of a resin sample spread on a flat surface, counting particles that differ in color or appearance from the base resin.
