5541E, alternate specification to and electrode potential

Is there a commercial equivalent to MIL-STD-5541E, class 3? Does anyone know the standard electrode potential of a 5541E, Class 3 coating?

Hello Steve, you should obtain a copy of specification no. ASTM B449, "Standard Specification for Chromates on Aluminum".
