Purpose. The purpose of the rating scale is to
allow comparison between vehicles and consistency between
personnel. It is important to recognize that rating corrosion
involves perception of an objectionable surface and much of the
judgment is subjective. The corrosion scales, provide some
objective measure that will guide subjective judgment.
Applicability. This white corrosion rating
scale guideline contains plated components including Exhaust Gas
Recirculation (EGR) valves, headlamp mounting brackets and
additional examples.
Remarks. The corrosion rating scale guidelines
contain corrosion rating scales, rating guidelines, and photographs
for the determination of corrosion severity on all vehicular parts,
including body and sheet metal, underbody and underhood components,
and fasteners. It is intended that the scales are used for both
corporate corrosion inspections and field surveys.
