AATCC 42 2013 Edition, January 1, 2013
Water Resistance: Impact Penetration Test
Includes all amendments and changes through Editorial Change , 2014
Additional Comments: SAME AS ISO 18695
Purpose and Scope
This test method is applicable to any textile fabric, which may or may not have been given a water-resistant or water- repellent finish. It measures the resistance of fabrics to the penetration of water by impact, and thus can be used to predict the probable resistance of fabrics to rain penetration. It is especially suitable for measuring the penetration resistance of garment fabrics.
The results obtained with this test method depend on the water repellency of the fibers and yarns and on the construction and finish of the fabric.
