Withdrawn Rationale:
These test methods cover procedures for the chemical analysis of copper-beryllium alloys having chemical compositions within specific limits.
Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in January 2011. This standard was withdrawn without replacement due to its limited use by industry.
1. Scope
1.1 These test methods cover procedures for the chemical analysis of copper-beryllium alloys having chemical compositions within the following limits:
ElementConcentrationRange,%
|
Copper97 to 98
Beryllium0.4 to 2.05
Nickel0.0 to 0.30
Cobalt0.0 to 0.3
Iron0.0 to 0.30
1.2 The analytical procedures appear in the following order:
Sections
|
Copper by the Electrolytic Method
Beryllium:
Phosphate Gravimetric Method
Aluminon (Photometric) Method
Nickel by the Dimethylglyoxime (Photometric) Method
Cobalt by the Nitroso-R-Salt (Photometric) Method
Iron by the Thiocyanate (Photometric) Method
1.3 This test method covers the determination of beryllium in concentrations from 0.1 to 3.0 %.
