GB/T 2915-2013
ActiveDetermination of conductivity of water extract of polyvinyl chloride resins
聚氯乙烯树脂 水萃取液电导率的测定
Application Summary AI generated
This standard specifies a method for measuring the electrical conductivity of a water extract from polyvinyl chloride (PVC) resins. It is applied in the plastics industry to assess the ionic purity and residual catalyst or additive content of PVC materials, particularly for quality control in manufacturing electrical insulation or medical-grade products. The test is conducted under controlled laboratory conditions to ensure the resin meets specified conductivity limits for downstream processing.
