Spray Rating Tester

Application

Spray Rating Tester is used to determine the resistance of any fabrics, which may or may not have been given a water-repellent finish, to surface wetting by water. It is not intended to predict waterproofness, since it does not measure the penetration of water through fabric. color or appearance occurs. It is not applicable to fabrics having a long pile or surface coating.
