Rationale: STABILIZED NOTICE
AMS QQ-A-200/3A has been declared "STABILIZED" by SAE AMS Non-Ferrous Alloys Committee D. This document will no longer be updated and may no longer represent standard industry practice. This document was stabilized because it is no longer state of the art and other documents contain technically equivalent requirements. Previously this document was reaffirmed. This document has never been technically updated by Committee D. Users of this document should refer to the cognizant engineering organization for disposition of any issues with reports/certifications to this specification; including exceptions listed on the certification.
NOTE: In many cases, the purchaser may represent a sub tier supplier and not the cognizant engineering organization.
AMS Committee D recommends that the following technically equivalent specifications be considered for future procurement. This listing does not constitute authority to substitute these specifications for the “STABILIZED” specification.
