List of references
Specifies requirements for coatings applied by mechanically impacting zinc powder on to the component surface. Also specifies requirements for the following: the type of chromate conversion treatment to be applied; the coating thickness; adhesion test; quality assessment of the corrosion resistance of unused coated parts when subjected to neutral salt spray testing. Coverage includes definitions and identification. Also includes detailed tables and annexes.
