Historical Standard: ASTM D5344-99 Standard Test Method for Extension Force of Partially Oriented Yarn
SUPERSEDED (see Active link, below)
ASTM D5344
1. Scope
1.1 This test method covers the measurement of extension force developed while drawing a partially oriented filament yarn.
1.2 This test method provides an estimate of the yarn orientation by means of continuous drawing of the yarn while running between pairs of draw rolls of different surface speeds.
1.3 This test method applies to partially oriented filament yarns less than 33.3 tex (300 denier), but it can be used for higher deniers by applying the test conditions as directed in Appendix X1.
1.4 This test method was written in SI units. The inch-pound units that are provided in this test method are not necessarily exact equivalents of the SI units. Either system of units may be used in this test method. In case of reference decisions, the SI units will prevail.
1.5 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.
