Description

ASTM E315-88-Reapproved1999

Historical Standard: Standard Test Methods for Chemical Analysis of Molybdenum

ASTM E315

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 to 18 Iron by the 1,10-Phenanthroline Photometric Method 19 to 29 Silicon by the Molybdenum Blue-Extraction Photometric Method 30 to 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.
