Water Vapour Permeability Test Chamber is used for determining the water vapour permeability (WVP) of leather or fabrics in an artificial environment in accordance with prescribed requirements.
Compared with the AT-L9014 WVP tester, this device features an extra climate chamber coming with a temperature and humidity controller, which is capable of providing a specific temperature and humidity atmosphere ( 23 ± 2℃, 50 ± 5% R.H. specified by ISO 20344) for the test.
Test Standards
GB/T 20991, SATRA TM172, EN / ISO 20344, ISO 20345, ISO 20347, BS EN 344, etc.
