It measures the resistance of fabrics to the penetration of water by low 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. 2 Normativereferences The following referenced documents are indispensable for the application of this document.
