TITLE : WATER REPELLENCY - SPRAY RATING
AWTA TEST CODE : T29C
APPLICATION : This method is applicable to all fabrics which may or may not have been given a water repellent finish or coating. It is not intended for use in predicting rain penetration resistance of fabrics, since it does not measure penetration of water through the fabric.
PRINCIPLE : A test specimen is subjected to a water spray under controlled conditions and the degree of surface wetting is assessed.
SAMPLES REQUIRED FOR TESTING
: The fabric sample should be approximately 1.5m2 in area. This sample should NOT have been cut within 2m of the lead end or tail end of the fabric piece, roll or lot.
INTERPRETATION : Ratings are as follows:
100 - No sticking or wetting of the upper surface
90 - Slight sticking or wetting of the upper surface
80 - Wetting of upper surface at the spray points
70 - Partial wetting of the whole of upper surface
50 - Complete wetting of the whole of upper surface
0 - Complete wetting of the whole of upper and lower surface
SERVICE TARGET : 6 days.
COST : See Fee List.
