The standard provides a test method for determining the corrosion potential of aluminium alloys. The method involves the measurement of the corrosion potential of aluminium alloys in an aqueous solution of sodium chloride with the addition of hydrogen peroxide to ensure adequate cathode reactants. The corrosion potential, also known as open circuit or resting potential, is a key parameter for assessing the corrosion behavior of aluminium alloys under specific environment conditions. This standard uses the International System of Units, does not include Miscellaneous Measurement Units, and does not cover all safety issues. Users need to establish appropriate safety and environment practices themselves.
