SCOPEThe material defined by this specification is a nitrocellulose thinner.2. APPLICATIONThis specificatio

3、n was released originally for material used as thinnerto dilute air drying Nitrocellulose based paints to spray viscosity. Ingeneral this material is used with Engine and Transmission Paints (PowerTrain Operations) including Polyvinyl Butyral and Alkyd based materials.It may also be used to dilute N

4、itrocellulose based Interior Repair Paint(Body & Assembly Operations).3. REQUIREMENTS3.1 QUALITY SYSTEM REQUIREMENTSMaterial suppliers and part producers must conform to QualitySystem Requirements, QS-9000. Material specification requirementsare to be used for initial qualification of materials. A C

5、ontrolPlan for ongoing production verification is required. This planmust be reviewed and approved by the relevant Ford Materialsactivity and/or Ford Supplier Technical Assistance (STA) prior toproduction parts submission. Appropriate statistical tools must beused to analyze process/product data and

6、 assure consistentprocessing of the materials.Part producers using this material in their products, must use Fordapproved materials and must conform to a process control plan whichhas been approved by STA and/or the relevant Materials Activity.3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSISFo

7、rd 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 material laboratory. All sam

8、ples shall produce IRspectra and thermograms that correspond to the reference standardwhen tested under the same conditions.ENGINEERING MATERIAL SPECIFICATIONWSK-M14J247-AWP 3948-b Page 2 of 33.3 FLASH POINTThe flash point shall conform to the safety regulations applicableto the plant and/or country

13、proval wasoriginally granted.Prior to making any change in the properties, compos ition,construction, color, processing or labeling of the materialoriginally approved under this specification, whether or not suchchanges affect the materials ability to meet the specificationrequirements, the Supplier

14、 shall notify Purchasing, Toxicology andthe affected Materials Engineering activity of the proposed changesand obtain the written approval of the Materials Engineeringactivity. Test data, test samples and a new code identification areto be submitted with the request.Substance restrictions imposed by

15、 law, regulations or Ford, applyto the materials addressed by this document. The restrictions aredefined in Engineering Material Specification WSS-M99P9999-A1.4. APPROVAL OF MATERIALSMaterials defined by this specification must have prior approval by theresponsible Materials Engineering activity. Su

16、ppliers desiring approvalof their materials shall first obtain an expression of interest from 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, sig

17、ned by aqualified and authorized representative of the test facility,demonstrating full compliance 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 mater

18、ial 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.5.
