2、S-M4D822-B3 FIBER/MINERAL REINFORCED MOLDING COMPOUND, PAINTED, EXTERIOR 1. SCOPE The material defined by this specification is a heat stabilized molding compound with approximately15% glass fiber and 25% mineral reinforcement, based on polyamide 6 resin. 2. APPLICATION This specification was releas

3、ed originally for material used in painted applications. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. This material do

4、es not contain UV stabilizers, long term exposure to direct sunlight will cause chalking or loss of gloss and must be painted for exterior visible applications. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Stand

5、ard Requirements for Production Materials (WSS-M99P1111-A). 3.1.1 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 usi

6、ng 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.1.2 This specification is based on virgin materials, however materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or postindustrial recyclates and repolymerised recycled m

7、aterials) should be used whenever technically feasible and following all materials and PV testing required by Ford Materials Engineering. 3.1.3 The use of recycled materials is encouraged per Ford Corporate ESOW Supplement 3. Materials containing recycled content (PIR/PCR) must be specified with a F

8、ord WRS material specification as defined by WRS-M99P42-A1. These materials cannot replacea virgin material without prior Ford approval and addition of the WRS specification to the engineering drawing. 3.1.4 Dry as molded: All test values indicated herein are based on material and specimens with moi

9、sture content not exceeding 0.2% except where noted (Moisture Conditioned) (test according to ISO 15512 Method B/ASTM D 6869). ENGINEERING MATERIAL SPECIFICATION WSS-M4D822-B3 Copyright 2016, Ford Global Technologies, LLC Page 2 of 7 All test materials have to be sealed in moisture-proof containers

10、and stored 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 50 C at a reduced pressure below 133 kPa. Conduct tests in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity. Indiv

11、idual 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. 3.1.5 Moisture Conditioned: The specimens shall be condition

12、ed 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. 3.1.6 Performance Criteria: Exte

13、rior painted substrates approved to WSS-M4D822-B3 must comply with all the requirements of WSS-M2P180-D/Latest (exterior). Parts must fulfill applicable SDS/CDS requirements. 3.1.7 As specified in WSS-M99P1111-A, paragraph 3.2, Ford Materials Engineering may request a Control Plan and Certificate of

14、 Analysis (CoA) containing lot testing requirements which must include, but are not limited to: Filler Content Impact Strength, Notched Charpy at 23 C Tensile Modulus 3.2 SAMPLE PREPARATION Unless otherwise specified all tests shall be carried out on injection molded, one-end gated test specimens. T

15、he test specimens A and D shall be molded using molding conditions defined in ISO 1874-02. See Table 1 for the number of specimens required. Specimens shall be as follows: Specimen A 150 minimum x 10 x 4.0 +/- 0.2 mm (ISO 527-2, Specimen Type 1A) Specimen B 355 x 100 x 1.0 +/- 0.1 mm (ISO 3795) Spec
