24、neering 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 submitted with the request. Substance restrictions imposed by law, regulations or Ford is applicable to the materials addres

25、sed 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 for the application. 4. APPROVAL OF MATERIALS This specification is intended to define the performance and/or

26、properties of finished parts or systems of combined materials. An Engineering Material Approved Source listing is not applicable for this specification. Product Engineering materials referenced in this document and/or the affected engineering drawing, which require prior Engineering approval, are sh

GENERAL INFORMATION The information below is provided for clarification and assistance in meeting the requirements of this specification. 5.1 RECOMMENDATIONS FOR MOUNTING . Only apply tape to absolutely clean and

28、dry surface. . Mating surface should be matched (contoured or parallel) to ensure 100 % contact of the bond area. . Once tape is applied to part and has been bonded and for any reason removed, it shall not be reused. . If the adhesive surface of the tape becomes soiled, the tape-backed part shall not be used unless tape is replaced. . The adhesive side of the tape shall not be touched or handled once the release liner has been removed.
