Textile Fabric Water Resistance Impact Penetration Tester China Supplier
Impact Penetration Tester is intended to determine the resistance of fabrics to the penetration of water by impact. Therefore it can be used to predict the probable resistance of fabrics to rain penetration.
It is applicable to any textile fabric, but it is especially suitable for assessing the penetration resistance of garment fabrics.
Principle of Impact Penetration Test
A volume of water is allowed to spray from a height of 610 ± 10 mm against a taut surface of a test piece backed by a weighed blotter. The blotter is then reweighed to determine water penetration, and the test piece is classified accordingly.
Test Standards
- AATCC42, ISO18695, GB/T33732
- AATCC 42 Water resistance: Impact penetration test
- ISO18695 Textiles – Determination of resistance to water penetration – Impact penetration test

Fabric Impact Penetration Test Procedure
- One end of the test sample is secured under the 152 mm spring clamp at the top of the inclined stand. Another 152 mm fixture, of 0.4536 kg in total mass, is fixed at the free end of the test sample. A standard blotter paper 152 × 230 mm is weighed to an accuracy of 0.1 g and inserted beneath the test piece.
- A 500 ± 10 ml volume of water at 27 ± 1℃ is poured into a funnel and allowed to spray onto the test specimen. The water should be poured into the funnel without imparting any swirling motion of the water in the funnel.
- Upon completion of the spraying period, the test sample is carefully lifted, the blotter beneath is removed, and then quickly reweighed to the nearest 0.1 g.
