5.1 The intent of this test method is to provide a means of measuring the shear strength of thin aluminum alloy wrought and cast products. Data obtained by this method are used to calculate minimum properties that can be utilized in the design of structural members such as found in aircraft. It is recognized that the loading conditions developed by this test method, and by most others, are not ideal in that they do not strictly satisfy the definition of pure shear. However, rarely do pure shear conditions exist in structures.

Note 1: Shear strength obtained by Test Method B831 is not interchangeable with that described in Test Methods B565 and B769. Shear strengths obtained by this test method have been shown to differ from values determined with other methods.5

5.2 Annex A1 provides a means of measuring the shear strength of additively manufactured products.

1.1 This test method covers single shear testing of thin wrought and cast aluminum alloy products to determine shear strength. It is intended for products that are too thin to be tested according to Test Method B769.

1.2 The values stated in inch-pound units are to be regarded as the 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 Annex A1 covers specific requirements related to additively manufactured products.

1.4 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.

1.5 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.
