KochWP 3948-a Page 1 of 3 INK PERFORMANCE, ELASTOMERIC MARKING ESP-M99P24-A1. SCOPEThis specification defines the performance requirements for a non-permanentmarkin

2、g ink for elastomeric components.2. APPLICATIONThis specification was released originally for material used to color codeelastomeric components to visually aid in assembly.3. REQUIREMENTS3.1 STATISTICAL PROCESSSuppliers must conform to the requirements of Ford Quality SystemStandard Q-101. A mutuall

3、y 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 SPECTROPHOTOMETRY AND/OR THERMAL ANALYSISFord Motor Company, at

4、 its option, may conduct infrared and/orthermal analysis of material/parts supplied to this specification.The IR spectra and thermograms established for initial approval shallconstitute the reference standard and shall be kept on file at thedesignated material laboratory. All samples shall produce I

5、R spectraand thermograms that correspond to the reference standard when testedunder the same conditions.3.3 CONDITIONING AND TEST CONDITIONSAll test values indicated herein are based on material conditioned ina controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relativehumidity for not less than 24

6、h prior to testing and tested under thesame conditions unless otherwise specified.NOT TO BE USED FOR NEW DESIGN2012 N Status No replacement named N.

7、g and shipping without flaking,chipping, powdering or peeling.3.4.2 ThicknessThickness shall be sufficient to make the color of themarking ink visible to the naked eye on the substrate.3.4.3 Substrate CompatibilityThe ink must not adversely affect the substrate.Test Method: Cut from the marked seal,

8、 a section of sealcontaining the fully cured marking ink. Immediately adjacentto the marked area, cut a section of seal free of the markingink. Perform hardness testing per ASTM D 1415. The hardnessreadings from both areas must agree within +/- 1 IRHD.3.4.4 Automatic Transmission Fluid Compatibility

9、Place a fully cured marked seal specimen in a beaker andcover with a currently approved automatic transmission fluid(see note 1). Age the seal and transmission fluid for 1 h at23 +/- 2 C. At the end of the aging period remove the sealand rub dry with a cloth. The original color of the inkshould stil

10、l be visible on the substrate.3.4.5 Humidity ResistancePlace the seal to be tested into a humidity cabinet set at aminimum of 95 +/- 2 % relative humidity and 38 +/- 2 C for 70h. After removal from the cabinet and cooling to roomtemperature there should be no flaking, chipping, peeling orcolor chang

13、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 samples and a new code identification areto be submitted with the request.Substance restrictions im

14、posed by law, regulations or Ford, apply tothe materials addressed by this document. The restrictions aredefined in Engineering Material Specification WSS-M99P9999-A1, unlessa different suffix (e.g., A2 or A3) is specified on the engineeringdocument for the application.4. APPROVAL OF MATERIALSMateri

15、als 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 theaffected Purchasing, Design and Materials Engineering activity. Uponrequest, the Supplier sh

16、all submit to the affected Materials Engineeringactivity its own laboratory report to the specification (test results, notnominal values), the material designation and code number, and testspecimens for Ford evaluation. Upon approval, the material will be addedto the Engineering Material Approved Source List.Note 1:For information on currently approved automatic transmission fluidscontact:Supervisor, Materials and Fasteners EngineeringFord Motor CompanyP.
