1.1 This test method covers the measurement of yarn number up to 4000 dtex (3600 denier) and related variability properties of filament and spun yarns using an automated tester with capability for measuring mass variability characteristics. 1.2 Yarn number variability properties include percent density spread (%DS), coefficient of variation (%CV), density frequency variation. Note 1—For determination of yarn number by use of reel and balance, refer to Test Method D 1907. For another method of measuring variability (unevenness) in yarn, refer to Test Method D 1425.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in inaccuracies of results. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use. |
