ActiveDetermination of water vapour transmission rate for plastic film and sheeting - Electrolytic detection sensor method
塑料薄膜和薄片水蒸气透过率的测定 电解传感器法
Application Summary AI generated
This standard specifies a method for determining the water vapor transmission rate (WVTR) of plastic films and sheets using an electrolytic detection sensor. It is primarily applied in the packaging industry to evaluate the moisture barrier properties of materials used for food, pharmaceutical, and electronic product packaging. The test is conducted under controlled temperature and humidity conditions to ensure consistent quality control and material selection.
