Does ASTM A967 Practice D apply to age hardened 17-4 ph stainless steel?

Does ASTM A967 [link is to spec at TechStreet] Practice D-Copper Sulfate Test apply to martensitic 17-4 ph stainless steel in the aged condition? I have passivated these parts per ASTM A ASTM A380 [link is to spec at TechStreet] Code F. I'm assuming this spec does not apply because the parts are in the matensitic condition, but I'm not 100% sure, please advise.

Thanks,
