ISO 18695:2007

Textiles — Determination of resistance to water penetration — Impact penetration test

ISO 18695:2007 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 low impact, and thus can be used to predict the probable rain penetration resistance of apparel fabrics. The test is best suited for fabrics of medium to loose construction where the Bundesmann rain-shower test (ISO 9865), or Rain Test (ISO 22958) is too severe. Fabrics that do not lie flat under tension are not applicable.
