Description / Abstract:
The practice applies to parts and materials used in vehicle
manufacture which are intended to be acceptable color matches to a
specified color standard. This practice is intended for use with
parts or materials that are opaque or nearly so and does not apply
to transparent materials. Materials covered by this practice
include topcoat paint finishes, interior soft trim, interior and
exterior hard trim, and exterior film.
Purpose
The intent of this practice is to precisely specify procedures
for instrumental color difference measurement of colored parts or
colored materials incorporated in the manufacture of vehicles. The
recommended practice provides a consistent engineering practice for
determination of color difference, for numerical communication of
color difference, and for determination of acceptance or rejection
compared to numerical tolerances. The practice is intended for use
as a specification and means of communication for color part
acceptance in a buyer-seller agreement.
