ASTM D 5035
Breaking Force and Elongation of Textile Fabrics (Strip Method)
ASTM D 5035 covers raveled strip and cut strip test procedures for determining the breaking force and elongation of most textile fabrics. Provision is made for wet testing. The raveled strip test is applicable to woven fabrics while the cut strip test is applicable to nonwoven fabrics, felted fabrics, and dipped or coated fabrics. This test method is not recommended for knitted fabrics or for other textile fabrics which have high stretch (more than 11 %). This test method shows the values in both inch-pound units and SI units. Inch-pound units is the technically correct name for the customary units used in the United States. SI units is the technically correct name for the system of metric units known as the International System of Units. The values stated in either acceptable metric units or in other units shall be regarded separately as standard. The values expressed in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining in any way.
A test specimen is clamped in a tensile testing machine and a force applied to the specimen until it breaks. Values for the breaking force and elongation of the test specimen are obtained from machine scales, dials, autographic recording charts, or a computer interfaced with the testing machine. The test method describes procedures for carrying out fabric tensile tests using four types of specimen, and three alternative types of testing machines.
The raveled strip test in this test method is considered satisfactory for acceptance testing of commercial shipments of woven textile fabrics because the method has been used extensively in the trade for acceptance testing. The same is true for the cut strip test for felted or nonwoven textile fabrics.
The method is not recommended for knitted fabrics because of their high stretch.
IPS conditions samples at 50% RH and 23° C. Customer should request test option 1C (25 mm width) or test option 2C (50 mm width). Additional charges apply if Raveled Strip Testing is requested.
