DESCRIPTION

1.1 This test method measures the resistance to slippage of warp yarns over filling yarns, or filling yarns over warp yarns, in woven upholstery fabrics, using a specific standard seam assembly by comparing the differences in test curves from a sewn and unsewn sample.

Note 1: This test method is derived from Test Method D434, from which appropriate changes have been made to make the method more applicable for upholstery fabrics.

Note 2: This test method is designed to be a fabric test and is considered to be technically different than Test Method D1683, which is considered to be a yarn / seam test.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
