Grab Test of Textile Fabrics
The breaking strength and elongation of textile fabrics may be determined using the grab test method specified in ASTM D5034. This test method covers the grab and modified grab test procedures for determining the breaking strength and elongation of most textile fabrics. The grab test procedure is applicable to woven, nonwoven, and felted fabrics, while the modified grab test procedure is used primarily for woven fabrics. The grab test is a tensile test where the central part of the specimen's width is tested in the grips. The modified grab test is similar with lateral slits cut into the sides of each specimen, except for the center. Provisions are made for wet testing.
