Textiles -- Determination of resistance to surface wetting (spray test) of fabrics

This standard has been revised by: ISO 4920:2012

Abstract

The method is applicable to all fabrics which may or may not have been given a water-resistant or water-repellent finish. It is not intended to predict the rain penetration resistance of fabrics, since it does not measure penetration of water through the fabric. Before testing carried out the specimen shall be conditioned for at least 24 h in the standard atmosphere for testing textiles.
