Spray Tester

Determination of water repellency of fabric against external wetting is carried out with the help of the spray tester. 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. In this test, a specified volume of distilled water is sprayed on a Test specimen, which has been mounted on a ring and placed at an angle of 450, so that the center of the specimen is 150mm below the spray nozzle. The Spray rating is determined by comparing the appearance of the specimen with the standard Rating Chart.
