GB/T 20975.13-2020 Methods for chemical analysis of aluminium and aluminium alloys—Part 13:Determination of vanadium content
Abstract
This part of GB/T 20975 specifies the spectrophotometric method using benzoyl benzidine and the ammonium sulfate ferrous titration method for determining the vanadium content in aluminum and aluminum alloys.
This part is applicable to the arbitral determination of vanadium content in aluminum and aluminum alloys. The measurement range of the spectrophotometric method using benzoyl benzidine is 0.000 5%~1.00%. The measurement range of the ammonium sulfate ferrous titration method is >1.00%~12.00%.
