Eaton, NA Controlled document at www.MATS Copyright 2014, Ford Global Technologies, LLC Page 1 of 6 PERFORMANCE,LAMINATED IN-COLOR FILM MATERIALS, WSS-M99P37-B CLASS “A“ SURFACE, EXTERIOR 1. SCOPE This specificat
2、ion 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 covering all processes including in-department and pre-delivery repairs. 2. APPLICATION
3、 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. 3. REQUIREMENTS Testing to this specification shall be performed in conjunction with th
4、e appropriate laminate material specification. Terminating exterior edges visible after assembly shall conform to the full requirements of this specification. In-department and pre-delivery repairs shall meets the requirement of this specification Parts must conform to the color requirements defined
5、 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 requirements of the adjacent b
6、ody region. Note: For in process color check the preferred method is SAE J1545, three angle CMC (Color Measurement Committee). 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements for production materials (WSS-M99
7、P1111-A). 3.2 SYSTEM COMPONENTS 3.2.1 Substrates Rigid polymers and rigid polymer blends, SMC, ABS, etc. Flexible polymers and flexible polymer blends, PU, PC, TEO, etc. 3.2.2 In-Department and Pre-delivery Repairs Repaired areas must meet the requirements of this specification. All repair materials
8、 and processes used should be approved by the affected Product Materials activity. ENGINEERING MATERIAL SPECIFICATION WSS-M99P37-B Copyright 2014, Ford Global Technologies, LLC Page 2 of 6 Number of repairs for repaired parts will be specified in the mutually agreed control plan. All repairs must be
9、 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 regrind that is stipulated in the mutually agreed
10、 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 should be cut from production representative part
11、s 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 weathering), representative panels (plaques) run through t
12、he production process may be substituted for production part specimens. 3.3 FILM PROPERTIES 3.3.1 Color (FLTM BI 109-01 Visual Assessment, SAE J1545, Three-Angle CMC) Shall match the Master Approved Sample color panel or the initial sample as approved by Design Center. 3.3.2 Gloss Report (FLTM BI 11
