2、7-A CLASS “A“ SURFACE, EXTERIOR NOT TO BE USED FOR NEW DESIGN 1. SCOPE This specification defines the performance of multi-layered film materials for all exterior body parts where best appearance and high durability are required. This system is specified for assembly plants and component suppliers c
3、overing 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 weatherstrip that require a class “A“ finish. T
4、his specification is to be applied to the 2006 model year and beyond. 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
5、 specification. In-department and pre-delivery repairs shall meets the requirement of this specification Parts must conform to the color requirements defined by the ford Color Harmony team. Note: For in process color check the preferred method is SAE J1545, three angle CMC. Material specification re
6、quirements are to be used for initial qualification of materials. 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 SYSTEM COMPONENTS 3.2.1 Substrates Rigid polyme

8、nologies, LLC Page 2 of 8 3.2.2 In-Department and Pre-delivery Repairs Repaired areas must meet the requirements of this specification. All repair materials and processes used should be approved by the affected Product Materials activity. Number of repairs for repaired parts will be specified in the
9、 mutually agreed control plan. All repairs must be in a complimentary color to the original finish by agreement with the receiving company. 3.2.3 Finished Parts Testing must be conducted on actual production parts. Parts made of flexible substrates, defined in para. 3.2.1, must contain the amount of
10、 regrind that is stipulated in the mutually agreed upon Control Plan. Panels of flexible substrates, with the appropriate regrind content, can be laboratory prepared (simulating production conditions) and used for long term weathering exposure, such as Florida and Arizona submissions. Test specimens
11、 should be cut from production representative parts when possible. Where part dimensions limit equipment access and testing, and/or part geometry or size is such that adequate test specimens cannot be obtained, or when production parts will not be available to support timing (e.g. long term weatheri
12、ng), representative panels (plaques) run through the production process may be substituted for production part specimens. 3.3 FILM PROPERTIES 3.3.1 Color As determined by (FLTM BI 109-01 Visual Assessment) Color Harmony team (SAE J1545, Three-Angle CMC) Shall match the Master Appearance Sample or in
