ASTM B577 – Standard Test Methods for Detection of Cuprous Oxide (Hydrogen Embrittlement Susceptibility) in Copper
Description:
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.
Scope
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.
