To demonstrate compliance, thesample size and method of testing shall be in accordance with FLTMBN 24-2.3.16 FLAMMABILITY TEST PROGRAMMaterials, portions of component

10、s, and composites governed by thisspecification must also comply with the requirements ofES-D3AB-11014-AA.3.17 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSISAll samples shall produce spectra or thermograms that correspond tothe reference standard when tested under the same conditions. Theinfrare

11、d spectra or thermograms established for initial approvalshall constitute the reference standard and shall be kept on fileat the designated material laboratory.ENGINEERING MATERIAL SPECIFICATION ESB-M5G26-FPage 3 of 33.18 SUPPLIERS RESPONSIBILITYAll materials supplied to this specification must be e

12、quivalent inall characteristics to the material upon which approval wasoriginally granted.Prior to making any change in the properties, composition,construction, color, processing or labeling of the materialoriginally approved under this specification, whether or not suchchanges affect the materials

13、 ability to meet the specificationrequirements, the 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 identificationare to be

14、submitted with the request.Substance restrictions imposed by law, regulations or Ford, applyto the materials addressed by this document. The restrictions aredefined in Engineering Material Specification WSS-M99P9999-A1,unless a different suffix (e.g., A2 or A3) is specified on theengineering documen
