24、FICATIONESZ-M2G313-A Printed copies are uncontrolled Copyright 2008, Ford Global Technologies, LLC Page 5 of 5 4. APPROVAL OF MATERIALS Materials defined by this specification must have prior approval by Materials Engineering. Suppliers desiring approval of their materials shall first obtain an expr

25、ession of interest from Purchasing Design and Material Engineering. Upon request, the Supplier shall submit to Materials Engineering its own laboratory report to the specification (test results, not nominal value), the material designation and code number, and test specimens for Ford evaluation. Upo

26、n approval, the material will be added to the Engineering Materials Approved Source List. 5. TOXICITY-OBJECTIONABLE ODOR The material shall contain no benzol (benzene), chlorinated or other toxic compounds, or hydrolysable chlorine derivatives, nor have an obnoxious or objectionable odor. 6. GENERAL

27、 INFORMATION The information below is provided for clarification and assistance in meeting the requirements of this specification. 6.1 MECHANICAL CONVECTION OVEN The mechanical oven(s) used to cure the material shall be capable of obtaining 190 C. metal temperature on the body steel (0.75mm) within

28、8-10 min. 6.2 SUBSTRATES 6.2.1 CRLC steel: 0.75mm thickness surface precoated with M-99C47-A Mineral Oil, as per Australian Standard ASSI937-1977 6.2.2 Electrogalvanised (zinc/nickel 30-30): 0.75mm thickness surface precoated with M-99C47-A Mineral Oil, as per Australian Standard AS1937-1977 6.2.3 A

Heat greatly accelerates aging. Under these storage conditions, the minimum shelf life of

30、the material shall be 6 months. When these materials are stored at temperatures below 23 C, they shall be conditioned at room temperature prior to application. Adequate conditioning permits the material to obtain its optimum application properties. 6.4 FLASH POINT 23 C (ASTM D 56-82) 6.5 VOLUME CHANGE It is expected that a material of this nature has an expansion of the approximate range 10-20%. Any material evaluated to this specification must specify on an ISIR the volume expansion as tested in 3.14. Material approval will be dependant on functional trialing.
