Historical Standard: ASTM D4724-10 Standard Test Method for Entanglements in Untwisted Filament Yarns by Needle Insertion
SUPERSEDED (see Active link, below)
ASTM D4724
1. Scope
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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
