| 1. Scope |
|
1.1 This test method covers the measurement of or visual evaluation of yarn slippage and other types of failures in the three most commonly used upholstery seams-warp sewn to warp (wale to wale), filling sewn to filling (course to course), and warp sewn to filling (wale to course). The stresses at the seam are created by imposing a cyclic, impact, and penetrating load which fatigues the seam construction. Note 1-Within this test method it is assumed, for simplicity, that the sample being tested is of a woven construction. In case the sample is of a knot construction, it is only necessary to substitute "wale" for "warp" and "course" for "filling" in the instructions.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. |
