This International Standard specifies a spray test method for
determining the resistance of any fabric - which may or may
not have been given a water-resistant or water-repellent
finish - to surface wetting by water.
It is not intended for use in predicting the rain penetration
resistance of fabrics, since it does not measure penetration of
water through the fabric.
