A. MIL-A-8625F was issued in 1993 and amended in 2003. Among the 2003 changes & clarifications: If sealing of Type III anodizing is specified, corrosion testing is also required.

Ed. note: True, they're 'free'. American shops taxed to give their Chinese & Indian competitors a free leg up on them; and somewhere in the mix is probably a beltway bandit whose political donations are being returned to him 50X over :-)

Q. Ken,

MIL-A-8625 Rev. F states that sealing can be specified to improve the corrosion resistance of Type III coatings. However, I do not believe it requires additional testing. Can you site the governing paragraph(s)?

A. If sealed Type III per MIL-A-8625F is specified, corrosion testing is required per amended Table II (monthly qualification tests).
