ASTM F2516-18 - 1.10.2018
 
Significance and Use

5.1 Tension tests provide information on the strength and the elastic and plastic properties of materials under uniaxial tensile stresses.

5.2 Tension tests, as described in this test method, also provide information on the superelasticity, as defined in Terminology F2005, of the material at the test temperature.

 
1. Scope

1.1 This test method covers the tension testing of superelastic nickel-titanium (nitinol) materials, specifically the methods for determination of upper plateau strength, lower plateau strength, residual elongation, tensile strength, and elongation.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
