Significance and Use

Tension tests provide information on the strength and ductility of materials under uniaxial tensile stresses. This information may be useful in comparisons of materials, alloy development, quality control, and design.

The results of tension tests from selected portions of a part or material may not totally represent the strength and ductility of the entire end product of its in-service behavior in different environments.

These test methods are considered satisfactory for acceptance testing of commercial shipments since the methods have been used extensively for these purposes.

Tension tests provide a means to determine the ductility of materials through the measurement either of elongation or reduction of area. However, as specimen thickness is reduced, tension tests may become less useful for the determination of ductility. For these purposes Test Method E 796 presents an alternative procedure for measuring ductility.

1. Scope

1.1 These test methods cover the tension testing of metallic foil at room temperature in thicknesses less than 0.006 in. (0.150 mm).

Note 1Exception to these methods may be necessary in individual specifications or test methods for a particular material.

1.2 Units The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
