Coated fabrics - Determination of resistance to penetration by water
1 Scope
This standard specifies a method for the determination of the resistance of coated fabrics to penetration by water when subjected to a specific hydrostatic pressure over a fixed period of time.
This standard is applicable to coated fabrics, and it may apply by reference for other waterproof fabrics.
