APPLICATION: This specification was released originally for material used to manufacture electrical connector

3、s and mirror covers. 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 therein is required for material/source approval. Appropriate statistical tools must be used to analyze proc

4、ess/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 and/or thermal analysis of material/parts supplied to this specification. The curves established for initial

5、 approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce curves that correspond to the reference standard when tested under the same conditions as those specified on the master curve. 3.3 MOLDING COMPOUND 3.3.1 Melt

6、Flow Rate 14 - 25 g/10 (ASTM D 1238, 266 C, 5.0 kg) min 3.3.2 Glass Fiber Content, by Weight 8 - 12 % (1 h at 649 C) 3.4 MOLDED TEST SPECIMEN 3.4.1 Preparation of Test Specimens All test specimens shall be injection molded in accordance with ASTM D 1897. The values of this specification are based on

7、 injection molded specimens unless otherwise specified. ENGINEERING MATERIAL SPECIFICATION ESB-M4D462-A1 Page 2 of 4 3.4.2 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

12、g part specification. All critical areas with respect to these properties shall be clearly designated on the engineering drawing. ENGINEERING MATERIAL SPECIFICATION ESB-M4D462-A1 Page 3 of 4 3.5.2 The following requirements will be used as acceptance criteria for molded parts. The tests indicated wi

13、ll be conducted by Ford Motor Company at its option or by the part molder as specified by the affected Design Engineering Activity or SQA. Melt Flow Rate, max Two times the (ASTM D 1238, actual value 266 C, 5.0 kg) obtained for virgin mater- ial from the same batch from which the part was molded. 3.

14、6 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be equivalent in 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 origin

15、ally approved under this specification, whether or not such changes affect the materials ability 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 Mat

16、erials Engineering activity. Test data, test samples and a new code identification are to be 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 W

17、SS-M99P9999-A1, unless a different suffix (e.g., A2 or A3) is specified on the engineering document 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

18、materials shall first obtain an expression of interest from the affected Purchasing, Design and Materials Engineering activity. Upon request, the Supplier shall submit to the affected Materials Engineering activity its own laboratory report to the specification (test results, not nominal values), th

19、e material designation and code number, and test specimens for Ford evaluation. Upon approval, the material will be added to the Engineering Material Approved Source List. 5.
