Heat greatlyaccelerates aging. Under
12、 these storage conditions, the minimumshelf life of the material shall be 6 months. However, whenstored at 0 C the shelf life is extended to 12 months. When thesematerials are stored at temperatures below 23 C, they shall beconditioned at room temperature prior to application. Adequateconditioning p
13、ermits the material to obtain its maximumapplication properties.3.8 QUALITYThe material shall be a smooth homogeneous mixture, free fromforeign materials and properties detrimental to normal productionoperations.3.9 SUPPLIERS RESPONSIBILITYAll materials supplied to this specification must be equival

15、ty to meet the specificationrequirements, the Supplier shall notify Purchasing, Toxicology andthe affected Materials Engineering activity of the proposedchanges and obtain the written approval of the MaterialsEngineering activity. Test data, test samples and a new codeidentification are to be submit
16、ted with the request.Substance restrictions imposed by law, regulations or Ford, applyto the materials addressed by this document. The restrictions aredefined in Engineering Materials Specification WSS-M99P9999-A1.4. APPROVAL OF MATERIALSMaterials defined by this specification must have prior approv
17、al 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 shall submit to the affected Materials Engineeringactivity
18、 a completed copy of their laboratory test reports, signed by aqualified and authorized representative of the test facility,demonstrating full compliance with all the requirements of thisspecification test results, not nominal values), the material designationand code number, and test specimens for
19、Ford evaluation. Fordsengineering approval of a material will be based on its performance tothis specification and on an assessment of suitability for intendedprocesses and/or applications. Upon approval, the material will be addedto the Engineering Material Approved Source List.ENGINEERING MATERIAL
20、 SPECIFICATION ESF-M2G331-APage 4 of 45. GENERAL INFORMATIONThe information given below is provided for clarification and assistancein meeting the requirements of this specification.5.1 This material contains epoxy resins and curing agents that undercertain conditions of use could be considered toxic. Prolongedand repeated skin contact with this material should be removedwith soap and water. Tools, equipment and fabricated parts can becleaned with solvents such as Xylol (M14J245) or Chlorothene(M5B58).
