    Withdrawn Rationale:

    These test methods cover procedures for the chemical analysis of copper-tellurium 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jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in March 2010. This standard was withdrawn without replacement due to its limited use by the industry.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. Scope

    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
