    Withdrawn Rationale:

    These test methods cover the chemical analysis of molybdenum and molybdenum alloys having chemical compositions within set limits.

    Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in June 2010. This standard was withdrawn without replacement due to its limited use by industry.

    1. Scope

    1.1 These test methods cover the chemical analysis of molybdenum and molybdenum alloys having chemical compositions within the following limits:

    ElementConcentration Range, %
    Carbon0.010 to 0.040
    Iron0.020 max
    Molybdenum99.25 to 99.99
    Nickel0.010 max
    Nitrogen0.0010 max
    Oxygen0.0030 max
    Silicon0.010 max
    Titanium0.005 to 0.55
    Zirconium0.06 to 0.12

    1.2 The test methods in this standard are contained in the sections indicated below:

    Sections
    Nickel by the Persulfate-Dimethylglyoxime Photometric Method9-18
    Iron by the 1,10-Phenanthroline Photometric Method19-29
    Silicon by the Molybdenum Blue-Extraction Photometric Method30-40

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary information is given in Section 5.
