Scope

1.1 This test method covers the measurement of the maximum sewn seam strength which can be achieved in woven fabrics when a force is applied perpendicular to the seam. The grab test procedure in Test Methods D1682, which are used to measure breaking force and elongation of textile fabrics, will be used in conjunction with this test method for measuring sewn seam strength.

1.2 This test method is restricted to sewn seams which may either be obtained from a previously sewn article or prepared from fabric samples.

1.3 This test method is used when a breaking force to rupture, a minimum elongation, or both are required to determine the sewn seam strength, seam slippage, or seam integrity of a particular fabric for a specified end use.

1.4 This test method does not predict actual wear performance of a seam since wear life is dependent upon other factors in addition to seam stressing.

1.5 The grab test procedures in Test Methods D1682 shall be used to determine any characteristic in fabric that can affect the measurement of sewn seam strength.

1.6 The values stated in either acceptable metric units (SI) 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 values in any way.

1.7 This standard does not purport to address the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.>
