BS EN ISO 9073-17:2008 PDF

1   Scope This part of ISO 9073 specifies a method for measuring the resistance of fabrics to the penetration of water by impact. The water penetration (spray impact) test is applicable to fabrics that are expected to exhibit a degree of water resistance or water repellency. The results obtained with this method depend on the water repellency of the fibres or the treatment applied to the finished material, as well as on the construction of the material.
