SCOPE The material define
2、d by this specification is a thermoplastic injection molded compound based on a polycarbonate copolymer and contains UV stabilization. 2. APPLICATION This specification was originally released for materials used for exterior components that require high gloss and exterior weathering performance with
3、out need for a coating, such as grilles. 2.1 LIMITATIONS This material should be evaluated for potential incompatibility with other materials that it may come in contact with. Refer to the appropriate performance specification. Materials approved to this specification may contain additives which inh
4、ibit adhesion, and therefore should not be used in painted applications. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD
5、file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.2 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24 h prior to testing in a controlled environment of 2
6、3 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.3 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms from initial material approval shall constitute the reference standard and shall be
7、 kept on file at the designated material laboratory. The material supplier shall ensure that all future material supplied to the specification shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.4 STANDARD REQUIREMENTS FOR PRODU
8、CTION MATERIALS 3.4.1 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mean and +/- 3 sigma values were to be reported. The specification minimum, maximum or range was established using 3 sigma data. For 2011 and beyond, refer
9、to Table 1 for number of samples required for each test. 3.4.2 This specification is based on virgin material and does not allow the addition of recycled content (PIR/PCR).
