APPLI CATIONThis specification was released originally for a backing material forseating vinyl.3. REQUIREMENTS3.1 STATISTICAL PROCESSSuppliers must conform to the requirements o

3、f Ford Quality SystemStandard Q -101. A mutually acceptable Control Plan as describedtherein is required for material/source approval. Appropriatestatistical tools must be used to analyze process/product data sothat variation in the final product is continuously reduced.3.2 INFRARED SPECTROPHOTOMETR

4、Y AND/OR THERMAL ANALYSISFord Motor Company, at its option, may conduct infrared and/orthermal analysis of material/parts supplied to this specification.The IR spectra and thermograms established for initial approvalshall constitute the reference standard and shall be kept on fileat the designated m

5、aterial laboratory. All samples shall produceIR spectra and thermograms that correspond to the referencestandard when tested under the same conditions.3.3 CONDITIONING AND TEST CONDITIONSAll test values indicated herein are based on material conditionedin a controlled atmosphere of 23 +/ - 2 C and 5

11、tics to the material upon which approval wasoriginally granted.ENGINEERING MATERIAL SPECIFICATION WSB-M9H117-BWP 3948-b Page 3 of 3Prior to making any change in the properties, composition,construction, color, processing or labeling of the materialoriginally approved under this specification, whethe

12、r or not suchchanges affect the materials ability to meet the specificationrequirements, the Supplier shall notify Purchasing, Toxicology andthe affected Materials Engineering activity of the proposed changesand obtain the written approval of the Materials Engineeringactivity. Test data, test sample

13、s and a new code identificationare to be submitted with the request.Substance restrictions imposed by law, regulations or Ford, applyto the materials addressed by this document. The restrictions aredefined in Engineering Material Specification WSS -M99P9999 -A1,unless a different suffix (e.g., A2 or

14、 A3) is specified on theengineering document for the application.4. APPROVAL OF MATERIALSMaterials defined by this specification must have prior approval by theresponsible Materials Engineering activity. Suppliers desiring approvalof their materials shall first obtain an expression of interest from

15、theaffected Purchasing, Design and Materials Engineering activity. Uponrequest, the Supplier shall submit to the affected Materials Engineeringactivity a completed copy of their laboratory test reports, signed by aqualified and authorized representative of the test facility,demonstrating full compli

16、ance with all the requirements of thisspecification (test results, not nominal values), the materialdesignation and code number, and test specimens for Ford evaluation. Fords engineering approval of a material will be based on itsperformance to this specification and on an assessment of suitabilityfor intended processes and/or applications. Upon approval, the materialwill be added to the Engineering Material Approved Source List.
