ActiveDetermination of water vapour transmission rate for plastics film and sheeting—Part 7：Calcium corrosion method
塑料薄膜和薄片水蒸气透过率的测定 第7部分：钙腐蚀法
Application Summary AI generated
This standard specifies a test method for determining the water vapour transmission rate of plastic films and sheets using a calcium corrosion sensor. It is applied in the packaging industry, particularly for evaluating the moisture barrier performance of flexible packaging materials used in food, pharmaceutical, and electronic product protection. The method is suitable for quality control and material comparison in laboratory testing contexts where high sensitivity to low water vapour transmission rates is required.
