These test methods cover procedures for the chemical analysis of chromium-copper alloys having chemical compositions within select limits.
Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in March 2010. This standard was withdrawn without replacement due to its limited use by the industry.
1.1 These test methods cover procedures for the chemical analysis of chromium-copper alloys having chemical compositions within the following limits:
Copper, %98 and over
Chromium, %0.6 to 1.2
Silicon, %0 to 0.10
Iron, %0 to 0.10
1.2 The analytical procedures appear in the following order:
Copper by the Electrolytic Method
Chromium by the Dichromate (Potentiometric) Method
Silicon by the Perchloric Acid Dehydration Method
