Withdrawn Rationale: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jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in June 2010. This standard was withdrawn without replacement due to its limited use by industry.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:
| Element | Concentration Range, % |
| Carbon | 0.010 to 0.040 |
| Iron | 0.020 max |
| Molybdenum | 99.25 to 99.99 |
| Nickel | 0.010 max |
| Nitrogen | 0.0010 max |
| Oxygen | 0.0030 max |
| Silicon | 0.010 max |
| Titanium | 0.005 to 0.55 |
| Zirconium | 0.06 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 Method | 9-18 |
| Iron by the 1,10-Phenanthroline Photometric Method | 19-29 |
| Silicon by the Molybdenum Blue-Extraction Photometric Method | 30-40 |
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.
