Historical Standard: ASTM D4724-99 Standard Test Methods for Degree of Filament Yarn Entanglement by Needle Insertion Methods
SUPERSEDED (see Active link, below)
ASTM D4724
1. Scope
1.1 These test methods cover three procedures for the determination of the degree of filament yarn entanglement using needle insertion. The test methods appear in the following order:
Sections Method 1-Degree of Filament Entangle- ment by Average Millimetre Pull 9 to 17 Method 2-Degree of Filament Entangle- ment in a Length of Yarn 17 to 25 Method 3-Degree of Filament Entangle- ment by Manual Method 25 to 321.2 The values stated in SI units are to be regarded as the standard.
1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
