AATCC 127
Water Resistance: Hydrostatic Pressure Test
This test method measures the resistance of a fabric to the penetration of water under hydrostatic pressure. It is applicable to all types of fabrics, including those treated with a water resistant or water repellent finish.
Water resistance depends on the repellency of the fibers and yarns, as well as the fabric construction.
The results obtained by this method may not be the same as the results obtained by the AATCC methods for resistance to rain or water spray.
This test method is performed without a restraint. If a restraint is required, use Test Method (TM) 208, Water Resistance: Hydrostatic Pressure Test Using a Restraint.
