Standard Test Method for Yarn Number Using Automatic Tester
|Publication Date:||10 September 2000|
|ICS Code (Yarns):||59.080.20|
1.1 This test method covers the measurement of yarn number of filament and spun yarns using automated testers. Some of the instruments are stand-alone and others are optional modules for instruments that perform additional tests.
1.1.1 The instruments are capable of measuring yarn numbers up to 4000 dtex (3600 denier).
Note 1--For determination of yarn number by use of reel and balance, refer to Test Method D1907.
1.2 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.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
