SCOPE The mate
2、rial defined by this specification is 15% glass fiber reinforced, polyamide 6 molding compounds for general purpose use. 2. APPLICATION This specification was released originally for material used for functional parts. 2.1 LIMITATIONS These materials absorb and retain moisture. Part design and toler
3、ances must accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. This material is not suitable for long term exposure to engine coolant, or direct exposure to strong acids or bases. It is not suitable for use above 155
4、C. Materials approved are not for Class A surface, color keyed applications as they do not contain UV stabilizers. 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 sp
5、ecification 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 and specime
6、ns with moisture content not exceeding 0.2% except where noted (Moisture Conditioned) (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 processing. If the moisture content
7、exceeds 0.2%,conditioning the material for a minimum of 16 h at 40 to 50 C at a reduced pressure below 133 kPa. Conduct tests in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing. 3
8、.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 ENGINEERING MATERIAL SPECIFICATION WSS-M4D665-B1 Copyright 20
9、16, Ford Global Technologies, LLC Page 2 of 7 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 PRODUCTION MATERIALS 3.4.1 Many 4D
10、 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 Table 1 for number of samp
11、les 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). 3.4.3 The use of regrind is permitted, for economic / environmental reasons. Part manufacturers using this specification must complete DV and PV testing wit
12、h the allowable amount of regrind and the maximum allowable regrind content must be specified 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 p
13、rocess (SREA). 3.4.4 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements if collective parts exceeds 100 cm2 or 100 g. Data must be included in material submission pac
14、kage. 3.4.5 Dry as molded All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% except where noted (Moisture Conditioned) (test according to ISO 15512 Method B/ASTM D6869). All test materials have to be sealed in moisture-proof containers and s
15、tored at 23 +/- 2 C for at least 24 h immediately after processing. If the moisture content exceeds 0.2%, conditioning the material for a minimum of 16 h at 40 to 50 C at a reduced pressure below 133 kPa. Conduct tests in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity. Individ
16、ual specimens shall not be removed from closed containers until immediately before testing. Moisture conditions results for Tensile Strength, Tensile Modulus, Charpy Impact, and Flexural Modulus can be found in the Ford Material Database. 3.4.6 Moisture Conditioned: The specimens shall be conditione
17、d to a moisture content of 1.0 to 2.0 wt% moisture then place the specimens in standard atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity for at least 1 h before testing (according to ISO 1110). Moisture content shall be reported to verify the moisture level. 3.4.7 Performance Criteria: Parts
18、 using these specifications must comply with all the requirements of WSS-M15P50-B/Latest (underhood, underbody) and WSS-M15P4-F/Latest (interior) and fulfill applicable SDS/CDS requirements.
