1.1 These test methods describe procedures for determining the presence of cuprous oxide (Cu2O) in products made from deoxidized and oxygen-free copper.

1.2 Inch-pound units are the standard. SI values given in parentheses are for information only.

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.

1.3 The test methods appear in the following order:

1.4 This test method describes a procedure by which the presence of cuprous oxide is determined by polarized light microscopy examination at a minimum magnification of 75.

1.5 This test method describes a procedure by which the presence of cuprous oxide is determined by microscopical examination under normal illumination at a minimum magnification of 75 after thermal treatment of the specimens.

1.6 This test method describes a procedure by which the presence of cuprous oxide (hydrogen embrittlement) is determined by bending thermally treated specimens into a flattened "U" shape.

1.7 This test method describes a procedure in which the presence of cuprous oxide (hydrogen embrittlement) is determined by subjecting thermally treated specimens to a predetermined number of bends.
