Description

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.
