Significance and Use:

These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.

Scope:

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 overChromium, %0.6 to 1.2Silicon, %0 to 0.10Iron, %0 to 0.10

1.2 The analytical procedures appear in the following order:

SectionsCopper by the Electrolytic MethodChromium by the Dichromate (Potentiometric) MethodSilicon by the Perchloric Acid Dehydration Method
