1 Scope

This standard specifies the superelastic nickel-titanium alloy tensile test method. This standard is applicable to the strength of the platform on the superelastic nickel-titanium alloy, the lower platform strength, the residual strain, the tensile strength and the uniform strain. Subject characterization and testing.
