This specification covers processes, pretreatments, and pre-primer surface preparations of metallic substrates for coating applicators. It covers metal surface preparation for delaying corrosion initiation and promoting primer adhesion. In addition, this specification covers the testing requirements for qualification of conversion coatings, the pretreatments and pre-primer coatings. This specification includes production validation requirements, which may also vary depending on the contract. Additional qualification requirements may be required based on each specific application. For all types and classes, unless contraindicated on drawings or contracts, materials containing hexavalent chromium (Cr6+) shall not be permitted on coated end items.
