Standard Test Methods for the Determination of Vanadium in Ferrovanadium and Vanadium Alloying Additives (Withdrawn 2005)

SCOPE
1.1 This test method covers the chemical analysis of ferrovanadium, vanadium carbide, and vanadium-aluminum having chemical compositions within the following limits:Element Concentration Range, %Aluminum0.01 to 65Carbon 0.01 to 20Chromium0.01 to 1Manganese0.01 to 1Silicon 0.05 to 10Vanadium25 to 90
1.2 The test methods in this standard are contained in the sections below: SectionsVanadium by the Permanganate Oxidation-Ferrous Ammo-nium Sulfate Titration Method to
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 hazard statements are given in Section 5 and in special "Warning" paragraphs throughout these test methods.
WITHDRAWN RATIONALE
This test method covers the chemical analysis of ferrovanadium, vanadium carbide, and vanadium-aluminum having chemical compositions within the following limits:Element Concentration Range, %Aluminum0.01 to 65Carbon 0.01 to 20Chromium0.01 to 1Manganese0.01 to 1Silicon 0.05 to 10Vanadium25 to 90
Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, this test method was withdrawn in May 2005. This standard is being withdrawn without replacement because it does not have ILS supporting data and most laboratories are using instrumental techniques for analysis rather than the old wet chemical methods.
