Standard Test Methods for Tension Testing Wrought and Cast Aluminum- and Magnesium-Alloy Products

SIGNIFICANCE AND USE
4.1 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 under certain circumstances.  
4.2 The results of tension tests of specimens machined to standardized dimensions from selected portions of a part or material may not totally represent the strength and ductility properties of the entire end product or its in-service behavior in different environments.  
4.3 These test methods are considered satisfactory for acceptance testing of commercial shipments and have been used extensively in the trade for this purpose.
SCOPE
1.1 These test methods cover the tension testing of wrought and cast aluminum- and magnesium-alloy products, with the exception of aluminum foil,2 and are derived from Test Methods E8, which cover the tension testing of all metallic materials.  
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: Foil is sheet metal less than 0.0079 in. thick. There is an overlap in the thickness range 0.006 to 0.0079 in. defined for foil and sheet. Sheet products in this thickness range are supplied to sheet product specifications and foil products in this thickness range are supplied to foil product specifications. Exceptions to the provisions of these test methods may need to be made in individual specifications or test methods for a particular material.
Note 2: A complete metric companion to Test Methods B557 has been developed—Test Methods B557M; therefore, no metric equivalents are presented in these test methods.

ASTM
ASTM B831-22(Test Method)
Standard Test Method for Shear Testing of Thin Aluminum Alloy Products

SIGNIFICANCE AND USE
5.1 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. 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: Results from this test method are not interchangeable with results from Test Methods B565 and B769. Shear strengths obtained by this test method have been shown to differ from values determined with other methods.3
SCOPE
1.1 This test method covers single shear testing of thin wrought and cast aluminum alloy products to determine shear ultimate strengths. 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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 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.

ASTM B746/B746M-22e1(Specification)
Standard Specification for Corrugated Aluminum Alloy Structural Plate for Field-Bolted Pipe, Pipe-Arches, and Arches

ABSTRACT
This specification covers corrugated aluminum alloy structural plate used in the construction of pipe, pipe-arches, arches, underpasses, box culverts, and special shapes for field assembly. The pipe, arches, and other shapes are generally used for drainage purposes, pedestrian and vehicular underpasses, and utility tunnels. Structural plates shall be fabricated from flat sheets or plates, corrugated, punched for bolted lap seams and curved to the required radius.
SCOPE
1.1 This specification covers corrugated aluminum alloy structural plate used in the construction of pipe, pipe-arches, arches, underpasses, box culverts, and special shapes for field assembly. Appropriate fasteners are also described. The pipe, arches, and other shapes are generally used for drainage purposes, pedestrian and vehicular underpasses, and utility tunnels. Aluminum box culvert shapes are covered in Specification B864/B864M.  
1.2 This specification does not include requirements for bedding, backfill, or the relationship between earth cover load and plate thickness of the pipe. Experience has shown that the successful performance of this product depends upon the proper selection of plate thickness, type of bedding and backfill, controlled manufacture in the plant, and care in the installation. The purchaser must correlate the above factors and also the corrosion and abrasion requirements of the field installation with the plate thickness. The structural design of corrugated aluminum structural plate pipe and the proper installation procedures are given in Practices B790/B790M and B789/B789M, respectively. A procedure for using life-cycle cost analysis techniques to evaluate alternate drainage system designs using corrugated metal pipe is given in Practice A930.  
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.  
1.4 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.

ASTM B769-11(2021)(Test Method)
Standard Test Method for Shear Testing of Aluminum Alloys

SIGNIFICANCE AND USE
5.1 The intent of this method is to provide a means of measuring the ultimate 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 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 2: This method is not interchangeable with that described in Test Method B565. Shear strengths obtained by Test Method B565 are about 10 % lower than those developed by this test method.  
5.2 The presence of a lubricant on the surface of the specimen and fixture may result in shear strengths up to 3 % lower than those determined in the absence of lubrication (see 8.1 and Test Method B565).
SCOPE
1.1 This test method covers double-shear testing of wrought and cast aluminum products to determine shear ultimate strengths.  
Note 1: The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.  
1.2 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.  
1.3 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.
