GB/T 20975.15-2020 Methods for chemical analysis of aluminium and aluminium alloys—Part 15:Determination of boron content
Abstract
This part of GB/T 20975 specifies the determination of boron content in aluminum and aluminum alloys by hydrofluoric acid sample dissolution-ion selective electrode method and mixed acid sample dissolution-ion selective electrode method.
This part is applicable to the arbitration determination of boron content in aluminum and aluminum alloys. The determination range of hydrofluoric acid sample dissolution-ion selective electrode method is 0.001% to 5.00%; the determination range of mixed acid sample dissolution-ion selective electrode method is >5.00% to 11.50%.
