ASTM D4034-92

1.1 This test method covers the measurement of the resistance to slippage of warp yarns or filling yarns in woven upholstery fabrics, when testing for yarn slippage at the seam.

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.

1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.3 This standard does not purport to address all of the safety problems, if any, 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.
