3、ssembly plants and component suppliers covering all processes including in-department and pre-delivery repairs. 2. APPLICATION This specification was released originally to define film laminate performance of exterior surfaces. This specification is applicable to all surfaces outboard of the weather
4、strip that require a class “A“ finish. 3. REQUIREMENTS Testing to this specification shall be performed in conjunction with the appropriate laminate material specification. Terminating exterior edges visible after assembly shall conform to the full requirements of this specification. In-department a
5、nd pre-delivery repairs shall meets the requirement of this specification Parts must conform to the color requirements defined by the Ford Color Harmony Team or equivalent. Body color components shall visually match the adjacent body region for orange-peel and waviness. Instrumental measurements suc
6、h as Wavescan or QMS may be used as a guide if measurement is feasible. Refer to the appearance requirements of the adjacent body region.
