GB/T 20975.11-2018 Methods for chemical analysis of aluminium and aluminium alloys—Part 11:Determination of lead content
Abstract
This part of GB/T 20975 specifies the determination method for lead content in aluminum and aluminum alloys.
Method I of this part is applicable to the determination of lead content in aluminum and aluminum alloys. When aluminum interferes with the determination of lead in aluminum and aluminum alloys, an equal amount of aluminum is added to the working curve to eliminate the interference, and other coexisting elements do not interfere with the determination of lead. The determination range of Method I is: 0.005% to 12.0%; This part of Method II is applicable to the determination of lead content in aluminum and aluminum alloys. All coexisting elements in aluminum and aluminum alloys do not interfere with the determination of lead. The determination range of Method II is: 0.0001% to 0.005%.
