2、5-A2 NOT TO BE USED FOR NEW DESIGN 1. SCOPE The materials defined by these specifications are mineral filled thermoplastic polyolefin (TEO) compounds suitable for blow molding or extrusion. 2. APPLICATION These specifications were released originally for materials used for blow molding of carburetor
3、 air intake ducts. Parts using this material should not be exposed to an environment of continuous operating temperature above 110 C. 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 descri
4、bed therein 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 infra
5、red and/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
6、that correspond 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 96 h prior to testing a
7、nd tested under the same conditions unless otherwise specified. 3.4 MOLDING COMPOUND A1 A2 3.4.1 Melt Flow Rate, g/10 2.5 0.4 minutes, max (ASTM D 1258, 230 C,2.16 kg) ENGINEERING MATERIAL SPECIFICATION ESH-M4D415-A1 ESH-M4D415-A2 WP 3948-b Page 2 of 3 A1 A2 3.5 MOLD TEST SPECIMEN 3.5.1 Specific Gra

10、and/or manufactured parts shall be specified on the Engineering drawing, Engineering parts specification and/or performance specifications. All critical areas with respect to these properties shall be clearly designated on the engineering drawing. 3.7 SUPPLIERS RESPONSIBILITY All materials supplied
11、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 labeling of the material originally approved under this specification, whether or
12、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 Materials Engineering activity. Test data, test sample
13、s and a new code identification are to be submitted with the request. ENGINEERING MATERIAL SPECIFICATION ESH-M4D415-A1 ESH-M4D415-A2 WP 3948-b Page 3 of 3 Substance restrictions imposed by law, regulations or Ford, apply to the materials addressed by this document. The restrictions are defined in En
14、gineering Material Specification WSS-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. Supp
15、liers desiring approval of their 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 a completed copy of their laboratory test reports, s
16、igned by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of this specification (test results, not nominal values), the material designation and code number, and test specimens for Ford evaluation. Fords engineering approval of a
17、 material will be based on its performance to this specification and on an assessment of suitability for intended processes and/or applications. Upon approval, the material will be added to the Engineering Material Approved Source List. 5. GENERAL INFORMATION The information below is provided for cl
