ASTM D5034 – Breaking Strength of Textile Fabrics

Standard: ASTM D5034 Standard Test Method for Breaking Strength and Elongation of Textile Fabrics (Grab Test)

Scope: Per ASTM D5034: "This test method covers the grab and modified grab test procedures for determining the breaking strength and elongation of most textile fabrics. Provisions are made for wet testing. The grab test procedure is applicable to woven, nonwoven, and felted fabrics, while the modified grab test procedure is used primarily for woven fabrics. This test method is not recommended for glass fabrics, or for knitted fabrics and other textile fabrics which have high stretch (more than 11%)."

Products: Textile fabrics

Procedure: Per ASTM D5034: "A 100-mm (4.0-in.) wide specimen is mounted centrally in clamps of a tensile testing machine and a force applied until the specimen breaks. Values for the breaking force and the elongation of the test specimen are obtained from…a computer interfaced with the testing machine."

Result: Test results such as breaking force and elongation may be reported.
