The intent of this test method is to provide a means of measuring the ultimate shear strength of thin aluminum alloy wrought and cast products. Data obtained by this test 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 definitions of pure shear. However, rarely do pure shear conditions exist in structures.

Note 1—This test method is not interchangeable with that described in Methods B 565 and B 769. Shear strengths obtained by this test method have been shown to vary from those developed by the other methods.³

1.1 This test method covers single shear testing of thin wrought and cast aluminum alloy products to determine shear ultimate strengths.

1.2 The values stated in inch-pound units are to be regarded as standard. The SI values given in parentheses 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.
