AATCC Water Impact Penetration Tester for AATCC42 water resistance
Impact Penetration Tester, is to determine the resistance of fabric
to the penetration of water by impact, and thus can be used to
predict the probable resistance of fabrics to rain penetration.
Suitable for measuring the penetration resistance of garment
fabrics, and also used to test the Water Resistance(Impact
Penetration test) performance of medical protective clothing.

How Water Penetration Tester works?
1. Clamp one end of the specimen under 152mm spring clamp at the
top of the inclined stand.
2. A standard blotter paper 152 x 230 mm is weighed to the nearest
0.1g and inserted beneath the test specimen.
3. Pour the distilled water into the funnel of tester and allow
spraying onto the test specimen.
4. The water should be poured into the funnel without imparting any
swirling motion of the water in the funnel.
5. Upon completion of the spraying period, the test specimen is
carefully lifted, the blotter beneath removed, and then quickly
reweighed to the nearest 0.1 g.
