Water Impact Penetration Testing

The water impact penetration tester measures the resistance of fabrics to the penetration of water by impact. A specified amount of water is sprayed against a taut specimen against adsorbent blotting paper. The paper is weighed before and after testing to determine the amount of water penetration. The tester complies with AATCC Test Method 42, Water Resistance: Impact Penetration Test. Sample Size: 178 × 330 mm / 7 x 13 in. Warp / machine direction of the fabric in the long direction.
