Spray Rating

Spray Rating



The Spray Test is a simple method to

determine the resistance of any fabric, which

may or may not have been given a waterresistant

or water-repellent finish, to surface

wetting by water. It is not intended to predict

waterproofness, since it does not measure the

penetration of water through fabric.

A specified volume of distilled water is sprayed

centrally onto an inclined test specimen.

Stringent quality control of the nozzle hole

pattern, combined with accurate height setting

above the specimen, ensure a consistent spray

flow and formation, critical to the requirements

of the International standards.

The spray rating is determined by comparing

the appearance of the tested specimen with

descriptive standards and photographs. The

AATCC Spray Test Rating Chart is available for

this purpose.
