3、LICATION This specification was released originally as a material replacement for steel in the IP cross-car beam, and may also be used in most underhood applications (see limitations for specifics). 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances must accommoda
4、te changes in part dimensions and physical properties due to moisture absorption or loss in theservice/assembly environment. This material does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. This material is not suitable for direct long term
5、exposure to engine coolant, or direct exposure to strong acids or bases. It is not suitable for continuous use above 150 C. 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 whe
6、n 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 through a Ford Materials Engineer. 3.2 CONDITIONING AND TEST CONDITIONS Dry as molded: All test values indicated herein are based on material a
7、nd specimens with moisture content not exceeding 0.2% except where noted (Moisture Conditioned, see paragraph 3.7.6) (test according to ISO 15512 Method B/ASTM D6869). All test materials have to be sealed in moisture-proof containers and stored at 23 +/- 2 C for at least 24 h immediately after proce
8、ssing. If the moisture content exceeds 0.2%, condition the material for a minimum of 16 h at 40 50 C at a reduced pressure below 133 kPa. ENGINEERING MATERIAL SPECIFICATION WRS-M4D1062-A1 Copyright 2017, Ford Global Technologies, LLC Page 2 of 8 Conduct tests in a controlled atmosphere of 23 +/- 2 C
9、 and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing. 3.3 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms from initial material approval shall constitute the reference standard and shall be k
10、ept 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 PRODUCT
11、ION 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 to
12、 Table 1 for number of samples required for each test. 3.4.2 The use of regrind is permitted, for economic/environmental reasons. Part manufacturers using this specification must complete DV and PV testing with the allowable amount of regrind and the maximum allowable regrind content must be specifi
13、ed on the engineering drawing. Any changes to what is specified on the drawing (no specific amount implies zero regrind) must be approved by Materials and PD Engineering through the formal Ford Motor Company process (SREA). 3.4.3 Materials requiring High Strain Rate, Creep or fiber oriented Tensile
14、Modulus may be required to test to the requirements of WSS-M99D68-A1/Latest, Thermoplastic Property Determination For CAE, High Strain Rate Tensile, Creep and Tensile Modulus. Material suppliers should be prepared to submit data upon request. 3.4.4 Performance Criteria: Parts using this specificatio
