Water Vapour Permeability Testing Apparatus Standards: JIS L1099, ASTM E96/E96M, GB/T 12704
Water Vapour Permeability Testing Apparatus is an environmental
tester suitable to water vapour permeability test of determination
for impermeability, water vapour permeability, air permeability of
sport suit, especially skiing and mountaineering sportswear.
The permeability content means the vapour capacity given off from
inside to outside of clothes, for perspiration due to difference
with outside air in temperature and vapour.
Put the sample in the moisture cup certain time at tank in steady
state. Date out the vapour capacity by the difference weight of
anhydrous calcium chloride.?
Inside of the tester, there are two sections of rotary sample
stand. Accordingly there are two fans, to blow the sample
parallelly, the speed can change.
The tester is also suitable to the water vapour packaging
