1.1 This test method covers the testing of thin copper alloy strip to determine its formability or its ability to resist cracking when forming around a specific radius. The criterion for failure is the occurrence of cracks found on the outer radius of curvature (convex).

1.2 This bend test is limited to strip 0.003 to 0.031 in. thick. (0.076 to 0.79 mm)

1.3 The size of the forming radii used in this test shall be 0.005 to 0.250 in. (0.127 to 6.35 mm).

1.4 The values stated in inch-pounds are to be regarded as the standard. The values given in parentheses are for information only.

1.5 This standard does not purport to address all of the safety problems, 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.
