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

Does ASTM A967 Practice D-copper sulphate ⇦ this on eBay or Amazon [affil links] Test apply to martensitic 17-4 ph stainless steel in the aged condition? I have passivated these parts per ASTM A380 Code F. I'm assuming this spec does not apply because the parts are in the martensitic condition, but I'm not 100% sure, please advise.

Thanks,
