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.
