Scope

For bulk specimens, tension tests provide an adequate means to determine the ductility of materials either through the measurement of elongation or reduction of area. For foil specimens, however, tension tests are not very useful for the determination of ductility. This test method, employing low-cycle fatigue, circumvents the difficulties arising from the continuous application of strain until fracture and determines the ductility indirectly from empirical low-cycle fatigue relationships for metals.

The results of ductility tests from selected portions of a metallic foil may not totally represent the ductility of the entire foil or its in-service behavior in different environments.

This test method is considered satisfactory for acceptance testing of commercial shipments, design purposes, service evaluation, manufacturing control, and research and development.

1.1 This test method covers the determination of ductility, that is, the ability to undergo plastic deformation in tension or bending before fracturing, of metallic foil in thicknesses up through 0.150 mm (0.0059 in.).

1.2 Values stated in SI units are to be regarded as the standard. Inch-pound units are provided for information only.

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