Significance and Use
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:
Microscopical Examination without Thermal Treatment
Microscopical Examination after Thermal Treatment
Closed Bend Test after Thermal Treatment
Reverse Bend Test after Thermal Treatment
