Scope

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.

1.1 These test methods cover procedures for the chemical analysis of copper-tellurium alloys having chemical compositions within the following limits:

Copper, % 98 and over Tellurium, %0.04 to 0.6Includes silver.

1.2 The analytical procedures appear in the following order:

SectionsCopper by the Electrolytic Method8 to 12Tellurium by the Dichromate (Volumetric) Method13 to 17
