SCOPE The material defined by this specification is an injection moldable thermoplastic polyolefin that has been modified to provide increased stiffness and dimensio

3、nal stability. 2. APPLICATION This specification was released originally for material used to fabricate scuff plates for doors. 3. REQUIREMENTS 3.1 STATISTICAL PROCESS Suppliers must conform to the requirements of Ford Quality System Standard Q-101. A mutually acceptable Control Plan as described th

4、erein is required for material/source approval. Appropriate statistical tools must be used to analyze process/product data so that variation in the final product is continuously reduced. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS Ford Motor Company, at its option, may conduct infrared an

5、d/or thermal analysis of material/parts supplied to this specification. The IR spectra and thermograms established for initial approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra and thermograms that c

6、orrespond to the reference standard when tested under the same conditions. 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tes

7、ted under the same conditions unless otherwise specified.

10、 At -29 +/- 1 C 0.90 J Test Method: A Gardner impact tester, per FLTM BO 17-2, equipped with a 12.7 mm diameter impact head and a 51 mm diameter base, shall be used for the test. Specimens 3.2 mm thick shall be conditioned at the specified temperature for 24 h minimum. Samples must be impacted withi

11、n 5 s after removal from the cold chamber. Any specimen which cracks less than 12.7 mm shall be defined as a pass. Note: Minimum plaque size shall be 75 mm by 150 mm. ENGINEERING MATERIAL SPECIFICATION ESB-M4D404-A WP 3948-b Page 3 of 4 3.5 WEATHERING RESISTANCE After exposure in accordance with 3.5

12、.1 and 3.5.2, the material shall show no color change in excess of the specified AATCC rating (AATCC Gray Scale for Evaluating Change in Color, 10 step).) In addition, there shall be no cracking, crazing or any other deterioration. A slight loss of gloss or chalking will be allowed provided an accep

13、table appearance can be achieved by washing with mild detergents and water (ratio 5:95 by volume) after the Florida exposure. Prior to testing, the colors shall be approved for color match by the Design Color Laboratory. All initial approvals will be based on the preliminary weatherometer exposure,

14、pending Florida exposure results for final approval. 3.5.1 Xenon Arc Weatherometer Rating 4-5 (SAE J1885, 1240 kJ/m2 exposure minimum, specimen size: 150 x 100 mm minimum, 3.2 +/- 0.2 mm thick, molded in smooth polished mold) 3.5.2 Florida Exposure, 12 months Rating 4-5 (FLTM BI 160-01, 5 deg south,

16、OGGING (FLTM BO 116-03) Fog Number, min 75 Formation of excessive amounts of clear film or droplets is cause for rejection. 3.8 ADDITIONAL REQUIREMENTS Specific requirements for material and/or manufactured parts shall be specified on the Engineering drawing, Engineering parts specification and/or p

17、erformance specifications. All critical areas with respect to these properties shall be clearly designated on the engineering drawing. ENGINEERING MATERIAL SPECIFICATION ESB-M4D404-A WP 3948-b Page 4 of 4 3.9 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be equivalent in

18、 all characteristics to the material upon which approval was originally granted. Prior to making any change in the properties, composition, construction, color, processing or labelling of the material originally approved under this specification, whether or not such changes affect the materials abil

19、ity to meet the specification requirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engineering activity of the proposed changes and obtain the written approval of the Materials Engineering activity. Test data, test samples and a new code identification are to be

20、submitted with the request. Substance restrictions imposed by law, regulations or Ford, apply to the materials addressed by this document. The restrictions are defined in Engineering Material Specification WSS-M99P9999-A1, unless a different suffix (e.g., A2 or A3) is specified on the engineering do

21、cument for the application. 4. APPROVAL OF MATERIALS Materials defined by this specification must have prior approval by the responsible Materials Engineering activity. Suppliers desiring approval of their materials shall first obtain an expression of interest from the affected Purchasing, Design an
