Product introduction
It is suitable for the water vapor transmission performance test of films, sheets, paper, fabrics, non-woven fabrics and related materials in the fields of food, medicine, medical equipment, daily chemicals, etc.
Test principle
Desiccant (weight gain method) or place water (weight loss method) in the sample cup; seal the sample cup with the sample and place it in the test box; control the temperature, humidity and wind speed of the test box; The difference in humidity drives the water vapor to penetrate the sample, and the mass of the sample cup increases or decreases; the mass of the sample cup is regularly weighed, and the performance parameters such as the water vapor transmission amount of the sample are calculated.
Standard
ASTM E96、GB/T 1037、GB/T 16928、GB/T 17146、GB/T 12704、GB/T 19082、GB/T 21332、ASTM D1653、ISO 2528、TAPPIT464、DIN 53122-1、YBB00092003
