scope:

This standard covers the surface condition requirements for uncoated and coated steel sheet, as well as aluminum, which will be cleaned, surface treated, primed and painted. These requirements apply to sheet metals stamped inside GM as well as by its parts and steel suppliers, processing centers and service centers.

The surface conditions covered by this specification include: Oxides, carbon and carbonaceous deposits, roughness, surface treatments such as passivation and conversion coatings and marking.

The intent of this specification is to insure the surface condition of the metal surface is compatible with subsequent paint processing to provide a high quality appearance and high durability that meet all of GM's global requirements. Due to the regional nature of manufacturing processes, suppliers must understand the different requirements in each region and must also meet the needs of the region using these materials.

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Typical Applications. Materials covered by this specification include, but are not limited to, steel and aluminium stampings, roll formed parts, tubes, used in body structure, chassis, powertrain, interior and exterior applications where the surface condition is important prior to preparation for application of paints or passivations.
