This standard specifies the method for the determination of chromium content in aluminum and aluminum alloys. This standard applies to the determination of chromium content in aluminum and aluminum alloys. Measuring range: 0.0030% to 0.60% (also applicable to aluminum alloys with a mass fraction of chromium up to 1.50%).
