9、32 +/- 2 C 1000 N 3.4.7 500 h salt spray 800 N (ASTM B 117) 3.4.8 500 h ultraviolet light exposure 1300 N (Equipment described in FLTM BV 7-2) 3.4.9 10 thermal cycles: 1000 N 4 h at 88 +/- 1 C, 4 h at -29 +/- 1 C, 16 h humidity (38 +/- 2 C and 95 - 100 % RH) . TEST METHOD: . The tongue and groove pl

10、aques shall consist of materials identified in para 5.1 and must be molded by an approved source as recommended by Body and Chassis Engineering. . Clean the surfaces to be bonded with a hot, soapy water solution. The soap shall be free-rinsing, similar to that used for glassware. After cleaning, the

11、 plaques are blown dry and aged at 23 +/- 2 C for 24 h to insure dryness. . Dispense an adequate amount of adhesive into the groove plaque. After the appropriate open time for the adhesive being tested, the tongue is inserted into the adhesive filled groove. Remove any excess adhesive. Maintain prop

12、er alignment of the assemblies during cure. ENGINEERING MATERIAL SPECIFICATION ESB-M11P44-A . Test the assemblies at a crosshead speed of 12.7 mm/minute. Note: Proper alignment of the test assembly is critical. Every effort should be made to maintain uniform tension across the bond area. Cleavage an

13、d/or peel of the bond area could yield inaccurate results. . Evaluate a minimum of three assemblies per condition. Report failure mode and peak load in newtons. 3.5 CREEP RESISTANCE No slippage (ASTM D 1780, prepare test samples per para 3.2, apply a 4.5 kg dead weight load to test samples and expos

15、 Cure bonded assemblies as indicated by the adhesive manufacturer. . Mechanically attach bonded test assembly to a 0.76 x 300 x 300 mm CRS base panel. Centrally locate test assembly on base panel. . Conduct test as outlined per FLTM BV 1-2 following steps 9, 10 and 11. Position panel in slam fixture

16、 with reinforcement facing inward. Subject each test assembly to 10 cycles of 6 slams per cycle at -29 +/- 2 C. 3.7 REAR LAMP PERFORMANCE REQUIREMENTS Parts assembled with adhesive shall meet all engineering requirements specified by design engineering and as indicated on the appropriate prints. 3.8

Functional trial results must be approved by the affected assembly operation and Design Engineering. Results shall be made available to Materials Engineering prior to m

18、aterial approval and release. 3.9 ADDITIONAL REQUIREMENTS Specific requirements for material and/or manufactured parts shall be specified on the engineering drawing, engineering parts specification and/or performance specifications. All critical areas with respect to these properties shall be design

19、ated on the Engineering drawing. ENGINEERING MATERIAL SPECIFICATION ESB-M11P44-A 3.10 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any change in the properti

20、es, composition, construction, color, processing or labeling of the material originally approved under this specification, whether or not such changes affect the materials ability to meet the specification requirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engi

21、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 apply to the materials addressed by t

22、his 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 Materials defined by this specification must have prior approval by the

23、responsible Materials Engineering activity. Suppliers desiring approval of their materials shall first obtain an expression of interest from the affected Purchasing, Design and Materials Engineering activity. Upon request, the Supplier shall submit to the affected Materials Engineering activity its

24、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 material will be added to the Engineering Material Approved Source List. 5.
