EdwardsWP 3948-a Page 1 of 2 LUBRICANT - TORQUE/CLAMPING ANTI-SEIZURE WSD-M13P8-A1CONTROL1. SCOPEThis specification defines the performance requirements for lubric

2、antswhich are applied to threaded parts to impart specific torque/clampinganti-seizure properties.It app lies for both the testing of the lubricant and for testing finishedparts which are treated with any of the approved lubricants.2. APPLICATIONThi s specification was originally released for spark

3、plug and similarapp lications operating at elevated temperatures and where prevention ofgalling and corrosion of mutual thread contact faces is required.3. REQUIREMENTS3.1 STATISTICAL PROCESSSupplie rs must conform to the requirements of Ford Quality SystemStand ard Q-101. A mutually acceptable Cont

4、rol Plan as describedtherein is required for material/source approval. Appropriatestatist ical tools must be used to analyze process/product data sothat variation in the final product is continuously reduced.3.2 APPLICATION OF THE LUBRICANTWhere finished parts are received in a lubricated condition,

5、 theresponsibility for application of the lubricant and method ofapplication shall be that of the parts supplier.Where l ubricant is supplied as bulk form, samples from top, bottoman d intermediate packaged containers shall exhibit no visualdifference in appearance or consistency.3.3 FINISHED CONDIT

6、IONThe lubricant shall be retained to threaded locations identified andnot be transferred by excessive quantity applications.There must be no significant change in the appearance of the partsafter application of the lubricant.ENGINEERING MATERIAL SPECIFICATIONWSD-M13P8-A1WP 3948-b Page 2 of 2 3.4 PE

7、RFORMANCE REQUIREMENTSLubricants, when applied to threaded fasteners, shall ensure that theTo rque/Clamping Force performance conforms to the appropriateEngineering specification.The lub ricant shall resist galling and corrosion when assessed bymeans of full engine tests including 180 hour Hi gh Spe

8、ed and 600 hourextended durability application.3.5 SUPPLIERS RESPONSIBILITYAll materials supplied to this specification must be equivalent inal l characteristics to the material upon which approval wasoriginally granted.Pri or to making any change in the properties, composition,constr uction, color,

9、 processing or labeling of the materialorig inally approved under this specification, whether or not suchchange s affect the materials ability to meet the specificationrequir ements, the Supplier shall notify Purchasing, Toxicology andthe affected Materials Engineering activity of the proposed chang

10、esand obtain the written approval of the Materials Engineeringactivity. Test data, t est samples and a new code identification areto be submitted with the request.Substance restrictions imposed by law, regulations or Ford, apply tothe materials addressed by this document. The restrictions aredefined

11、 in Engineering Material Specification WS S-M99P9999-A1, unlessa different suffix (e.g., A2 or A3) is specified on the engineeringdocument for the application.4. APPROVAL OF MATERIALSMat erials defined by this specification must have prior approval by theresp onsible Materials Engineering activity.

12、Suppliers desiring approvalof thei r materials shall first obtain an expression of interest from theaffec ted Purchasing, Design and Materials Engineering activity. Uponrequest, the Supplier shall submit to the affected Materials Engineeringactivity a completed copy of their laboratory test reports,

13、 signed by aqualified and authorized representative of the test faci lity, demonstratingful l compliance with all the requirements of this specification (testresults, not nominal values), the material designation a nd code number, andtes t specimens for Ford evaluation. Fords engineering approval of amateri al will be based on its performance to this specification and on anassessment of suitability for i ntended processes and/or applications. Uponapprov al, the material will be added to the Engineering Material ApprovedSource List.
