14、shall not burn, or transmit a flame across its surface, at a rate of more than 100 mm/min. To demonstrate compliance, the sample size and method of testing shall be in accordance with FLTM BN 24-2. 3.6 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be equivalent in all ch

15、aracteristics to the material upon which approval was originally granted. Prior to making any change in the properties, composition, construction, color, processing or labelling of the material originally approved under this specification, whether or not such changes affect the materials ability to

16、meet the specification requirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engineering activity of the proposed changes and obtain the written approval of the Materials Engineering activity. Test data, test samples and a new code identification are to be submitt

17、ed with the request. Substance restrictions imposed by law, regulations or Ford, apply to the materials addressed by this document. The restrictions are defined in Engineering Material Specification WSS-M99P9999-A1, unless a different suffix (e.g., A2 or A3) is specified on the engineering document

18、for the application. 4. APPROVAL OF MATERIALS Materials defined by this specification must have prior approval by the responsible Materials Engineering activity. Suppliers desiring approval of their materials shall first obtain an expression of interest from the affected Purchasing, Design and Mater

19、ials Engineering activity. Upon request, the Supplier shall submit to the affected Materials Engineering activity its own laboratory report to the specification (test results, not nominal values), the material designation and code number, and test specimens for Ford evaluation. Upon approval, the ma

20、terial will be added to the Engineering Material Approved Source List. ENGINEERING MATERIAL SPECIFICATION ESB-M4D345-B ESB-M4D345-C WP 3948-bPage 4 of 4 5.
