About This Item

 

Full Description

1.1 This test method covers two options for the measurement of entanglements in untwisted filament yarns using needle insertion options for instrument (A) and manual (B) techniques.

1.2 The values stated in either SI or inch-pound units (in parentheses) are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other without combining values in any way.

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.
