TEXTILE TEST METHODS: TEXTILE FABRICS — DETERMINATION OF RESISTANCE TO WATER PENETRATION — HYDROSTATIC PRESSURE TEST
This National Standard of Canada is based on International Standard ISO 811:1981.
This International Standard specifies a hydrostatic pressure method for determining the resistance of fabrics to penetration by water. The method is primarily intended for dense fabrics, e.g. ducks, tarpaulins and tentings.
