รายละเอียดเอกสาร

This test method measures the resistance of a fabric to the penetration of water under hydrostatic pressure while restrained by an acrylic plate. 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. Results may not be the same as those obtained by hydrostatic water resistance testing without a restraint.
