Historical Standard: Standard Test Method for Bend Test for Determining the Formability of Copper and Copper Alloy Strip
ASTM B820
Scope
1.1 This test method describes the technique of bend testing copper and copper alloy strip samples to determine product formability or the ability to resist cracking when forming a bend around a specific radius. The criterion for failure is the occurrence of cracks on the outer radius of curvature (convex).
1.2 This bend test is limited to strip from 0.003 to and including 0.031 in. thick. (0.076 to and including 0.79 mm).
1.3 The size of the forming radii used in this test shall be 0.005 to and including 0.250 in. (0.127 to and including 6.35 mm).
1.4 Units – The values stated in inch-pounds 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.
1.5 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.
