Spray Rating Tester 
Product Information 
To determine the surface wetting resistance of fabrics. Comprising a metal framework allowing distilled water to be sprayed through a nozzle onto a test specimen at 45° and 150mm below the nozzle. The appearance of the specimen is compared against an optional photographic scale. 
Technical Parameters
a) Glass funnel: φ150 × 150mm (volume approximately 500 ml)
b) Sample press release angle: 45 °
c) Sample clip diameter: φ150mm
d) Nozzle head to the sample center distance: 150mm
e) Dimensions: 500 × 400 × 500mm (L × W × H)
The Spray Test is a simple method to determine the resistance of any fabric, which may or may nothave been given a water-resistant or water-repellent finish, to surface wetting by water.
