SCOPE This specification defines the minimum durability and performance requirements of anodized aluminum for bright decorative trim components. 2. APPLICATION This performance specification was released originally for anodized aluminum outer be
3、lt moldings. 2.1 LIMITATIONS Any cleaning agent containing a combination of ethoxylated C12-15 fatty acid and sodium metasillicate should not be used to clean this material (example: Motorcraft Multipurpose Cleaner). Surface attack will occur leaving a chalky substance on the surface. 3. REQUIREMENT
4、S 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 ANODIZED ALUMINUM PERFORMANCE MANAGEMENT All materials evaluated under this performance specification must have
5、 Supplement A completed and signed by Ford Materials Engineering, the material/coatings supplier, and the Tier One supplier. The Supplement A and specification data will be stored in the Ford Materials Database (FMD). If the aluminum is being applied to an outer belt molding, compatibility of the an
6、odized aluminum with seal material (s) is the responsibility of the Tier One supplier. The Tier One supplier shall have the seal tested against the applicable performance specification requirements. Table 2.0 describes the construction of the anodized aluminum, and must be submitted with Supplement
7、A. (Reference Supplement A). The Tier One supplier is responsible for including Table 2.0 and this performance specification on the part drawing. 3.3 FINISHED PARTS Testing must be conducted at Design Verification (DV) and Product Validation (PV) per Table 1.0 (including Supplement A), unless otherw
