Significance and Use
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.
Scope
1.1 These test methods cover the chemical analysis of chromium and ferrochromium having chemical compositions within the following limits:
| Element | Concentration, % |
| Aluminum | 0.25 max |
| Antimony | 0.005 max |
| Arsenic | 0.005 max |
| Bismuth | 0.005 max |
| Boron | 0.005 max |
| Carbon | 9.00 max |
| Chromium | 51.0 to 99.5 |
| Cobalt | 0.10 max |
| Columbium | 0.05 max |
| Copper | 0.05 max |
| Lead | 0.005 max |
| Manganese | 0.75 max |
| Molybdenum | 0.05 max |
| Nickel | 0.50 max |
| Nitrogen | 6.00 max |
| Phosphorus | 0.03 max |
| Silicon | 12.00 max |
| Silver | 0.005 max |
| Sulfur | 0.07 max |
| Tantalum | 0.05 max |
| Tin | 0.005 max |
| Titanium | 0.50 max |
| Vanadium | 0.50 max |

1.2 The analytical procedures appear in the following order:
| Sections | |
| Arsenic by the Molybdenum Blue Photometric Method | 9-19 |
| Lead by the Dithizone Photometric Method | 20-30 |
| Chromium by the Sodium Peroxide Fusion-Titrimetric Method | 31-37 |
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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 5.
