SCOPEThe material defined by this specification is an ar

2、omatic hydrocarbon.2. APPLICATIONThis specification was released originally for material used to reduceproduction clearcoats.3. REQUIREMENTS3.1 QUALITY SYSTEM REQUIREMENTSMaterial suppliers and part producers must conform to QualitySystem Requirements, QS-9000. Material specification requirementsare

3、 to be used for initial qualification of materials. A ControlPlan 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 statistica

4、l tools must beused to analyze process/product data and 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

5、.2 INFRARED SPECTROPHOTOMETRY 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 kep

6、t on fileat the designated material 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 atm

7、osphere of 23 +/- 2 C and 50 +/- 5 % relativehumidity for not less than 24 h prior to testing and tested underthe same conditions unless otherwise specified.ENGINEERING MATERIAL SPECIFICATIONWSS-M14J514-AWP 3948-b Page 2 of 23.4 SPECIFIC GRAVITY AT 20 C 0.859 - 0.876(ASTM D 891B)3.5 COLOUR Clear3.6

9、y change in the properties, composition,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 shall notify Purchasing, Toxicology andthe affe

10、cted Materials Engineering activity of the proposed changesand obtain the written approval of the Materials Engineeringactivity. Test data, test samples and a new code identificationare to be submitted with the request.Substance restrictions imposed by law, regulations or Ford, applyto the materials

11、 addressed by this document. The regulations aredefined in Engineering Materials Specification WSS-M99P9999-A1.4. APPROVAL OF MATERIALSMaterials defined by this specification must have prior approval by theresponsible Materials Engineering activity. Suppliers desiring approvalof their materials shal

12、l 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, signed by aqualified and authorized representative

13、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 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.
