Scope

1.1 These test methods cover the chemical analysis of ferroniobium having chemical compositions within the following limits: Element Composition, % Aluminum 2.00 max Carbon 0.30 max Chromium 2.00 max Cobalt 0.25 max Lead 0.01 max Manganese 3.00 max Niobium 40.00 to 75.00 Phosphorus 0.05 max Silicon 4.00 max Sulfur 0.03 max Tantalum 7.00 max Tin 0.15 max Titanium 5.00 max Tungsten 0.50 max 1.2 The test methods appear in the following order: Sections Separation of Niobium, Tantalum, and Titanium by the Ion-Exchange Test Method 15 and 16 Titanium by the Spectrophotometric Test Method [0.05 % to 5.0 %] 17 – 21 Niobium by the Gravimetric Test Method [40 % to 75 %] 22 – 23 Tantalum by the Gravimetric Test Method [1 % to 7 %] 24 – 25 Tantalum by the Spectrophotometric Test Method [0.25 % to 1 %] 26 – 30 1.3 Units—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 the user of this standard to consult and establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 6, and specific warning statements in 11.1. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
