Significance and Use
5.1 The intent of this method is to provide a means of measuring the shear strength of 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 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 B769 is not interchangeable with that described in Test Method B565 and B831. Shear strengths obtained by this test method have been shown to differ from values determined with other methods.5
5.2 The presence of a lubricant on the surface of the specimen and fixture can result in shear strengths up to 3 % lower than those determined in the absence of lubrication (see 9.1 and Test Method B565).
5.3 Annex A1 provides a means of measuring the shear strength of additively manufactured products.
Scope
1.1 This test method covers double-shear testing of wrought and cast aluminum products to determine shear strength.
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.
