2、 1 of 8 POLYCARBONATE (PC), GENERAL PURPOSE, EXTERIOR WSS-M4D1051-A1 POLYCARBONATE (PC), GENERAL PURPOSE, INTERIOR WSS-M4D1051-A2 1. SCOPE The material defined by this specification is a thermoplastic injection molded compound based on polycarbonate. This is a non UV-stable material. 2. APPLICATION

3、WSS-M4D1051-A1: This specification was released originally for materials used for headlamp lenses and rear lamp housings and protected by UV resistant coatings. WSS-M4D1051-A2: This specification was released originally for materials used for general purpose applications not requiring optical clarit

4、y, such as instrument cluster light filters. This material may be color pigmented when optical transparency is not required. 2.1 LIMITATIONS This material does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. 3. REQUIREMENTS 3.1 APPROVED SOURCE

5、S 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 file, or other documents. The list of approved sources is located within Ford at or available externally th

6、rough 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 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environm

7、ent 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 kept on file at the designated material laboratory. The material supplier shall ensure that all future mate

8、rial 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 PRODUCTION MATERIALS 3.4.1 Many 4D resin specifications prior to 2011, identified certain requirements with the s

9、ymbol (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.
