The estimation of the test involves visual appreciation of the surface of the fabric (number of absorption points on the surface). The repellency of a garment worn in foul weather conditions is very important. The Spray Test method is used for determining the resistance of any fabric, which may or may not have been given a water resistant/ repellant finishing surfacing wetting by water. A good repellency will increase the comfort during use. The repellency tends to decrease during washing, so a re-impregnation of a water repellent product is advised.
