Organization: ASTM
Publication Date: 1 January 2007
Status: inactive
Page Count: 5
ICS Code (Yarns): 59.080.20
scope:

This test method covers the determination of elastic properties of "as produced" elastomeric yarns made from rubber, spandex or other elastomers. Elastic properties include force at specified elongations, permanent deformation and stress decay. Other hysteresis related properties can be calculated.

NOTE 1-For a method designed specifically for testing rubber threads, refer to Test Method D 2433.

This test method is not applicable to covered, wrapped, or core-spun yarns or yarns spun from elastomeric staple.

This test method is applicable to elastomeric yarns having a range of 40 to 3200 dtex (36 to 2900 denier).

The values stated in either SI units or U.S. Customary units are to be regarded separately as standard. Within the text, the U.S. Customary units are in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.

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.
