This standard covers the standard methods and materials used for the protective surface treatments and finishes used on aerospace weapons system parts (including spares) and assemblies (such as fuselages, wings, cowlings, empennage, and rotor blades). This standard does not intend to address the application of solid film lubricants as a finishing system, nor does it address electroplating or other metallic coatings. This standard does not apply to equipment (such as propellers, electrical and electronic equipment, power plants, and instruments) or to standard contractor purchased accessories, (such as electric motors, generators, switches, hydraulic valves, and similar parts), unless specifically referenced in the item specification or drawing.
