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 such as Specification A550. 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. |

1. Scope | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1.1 These test methods cover the chemical
analysis of ferroniobium having chemical compositions within the
following limits:
1.2 The test methods appear in the following order:
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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 precautionary statements are given in Section 6, and specific warning statements in 11.1. 10.1 These test methods cover the determination of niobium, tantalum, and titanium in ferroniobium from 40 % to 75 %, 0.25 % to 7 %, and 0.05 % to 5.0 %, respectively. |
