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the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, this test method was withdrawn in May 2005. This standard is being withdrawn without replacement because it does not have ILS supporting data and most laboratories are using instrumental techniques for analysis rather than the old wet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.
