It is specified for vehicle bumpers, claddings, bodyside moldings, and other parts visible after assembly. 3. REQUIREMENTS The paint

4、 materials must be selected from the Painted Parts Strategy List using paints from suppliers on the Ford Approved Source List (ASL), unless a waiver is granted by Materials Engineering. All parts must also meet the appropriate DVP & R and Subsystem Design Specification requirements. All visible part

5、s of the component, including terminating exterior edges visible after assembly shall conform to the full requirements of this specification. Any localized post mold operations (Flame Treating, Sanding,) prior to painting requires the additional testing as noted in the last column of Table 1. All ar

6、eas of the component visible after assembly must be evaluated/tested, including flanges, parting lines, areas subject to post-mould treatment, styling lines and grooves. In-department, pre-delivery and refinish paint repairs shall meet the requirements of this specification. Parts must conform to th

7、e 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 such as Wavescan or QMS may be used as a guide if measurement is feasible. Refer to the appearance re
