Scope

5.1 These test methods determine whether copper products will be resistant to embrittlement when exposed to elevated temperatures in a reducing atmosphere.

5.1.1 It is assumed that all who use these test methods will be trained personnel capable of performing these procedures skillfully and safely. It is expected that work will be performed in a properly equipped facility.

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 The test methods appear in the following order:

	Sections
Microscopical Examination without Thermal Treatment	9 – 11
Microscopical Examination after Thermal Treatment	13 – 15
Closed Bend Test after Thermal Treatment	17 – 19
Reverse Bend Test after Thermal Treatment	21 – 23

1.3 Units—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.

1.4 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 stand......
