Book excerpt: This Part of GB/T 20975 specifies the method for determination of lead content in aluminium and aluminium alloys. Method 1 of this Part is applicable to the determination of lead content in aluminium and aluminium alloys. Aluminium in aluminium and aluminium alloys interferes with the determination of lead. The same amount of aluminium is added to the working curve to eliminate interference, and other coexisting elements do not interfere with the determination of lead. The measurement range of Method 1 is: >0.005%~12.0%. Method 2 of this Part applies to the determination of lead content in aluminium and aluminium alloys. All coexisting elements in aluminium and aluminium alloys do not interfere with the determination of lead. The measurement range of Method 2 is: 0.0001%~0.005%.
