Scope

1.1 These test methods cover measurement of the elastic behavior of fibers by assessing their ability to recover strain-induced energy, and to recover their original dimensions following a known extension. Since the crimp in a fiber alters the initial shape of the stress-strain curve, separate procedures are described for uncrimped and crimped fibers.

Note 1-For the determination of the elastic properties of elastomeric yarns, refer to Test Method D2731, Test Method for Elastic Properties of Elastomeric Yarns (Constant-Rate-of-Extension Machines).

1.2 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.
