6、ls The panels shall be 300 x 300 x 1 mm flat cold rolled low carbon steel body panels. A 6 mm hole is drilled in the center of one end for suspending the panel. Panels are considered flat when a 8 mm feeler gage cannot be inserted between the metal and a flat glass surface with either surface up and

7、 measured at 13 mm from each corner. FORD LABORATORY TEST METHOD BV 101-01 Page 2 of 4 Copyright 2000, Ford Global Technologies, Inc. Conditioning and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative h

8、umidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure 1. Clean and phosphate coat the steel panels in accordance with Performance Specification ESB-M3P1-A. 1A. Where specification requires, CRLC steel shall be coated with mill oil.

9、 Clean panel and add 0.2 cc of mill oil (such as M99C47-A) and spread evenly over entire 300 x 305 mm surface with fingertips. 2. Material application must be made within a period of 8 h after oil application. Spray the phosphate coated panels with ESB-M6J102-A body primer. Dry film thickness, bakin

10、g time and temperature to be in accordance with the specification requirements for ESB-M6J102-A. 3. Cool each panel to 23 +/- 2 C, then weigh and record. 4. Mask off the top 13 mm of each panel where it fits into the slamming fixture. 5. Spray the panel evenly with the test material at .23 - .25 g p

11、er cm2. 5A. Spray the panel evenly with the test material at .14 - .16 g per cm2 (dry weight). 6. Remove the masking tape and air dry the test panels at 23 +/- 2 C for the time as indicated in the specification requirements. 7. Bake the panels in a constant temperature oven with forced circulation.

12、The time and temperature used is indicated in the specification requirements. 8. Cool the panels to 23 +/- 2 C, weigh and record weight of each panel. 9. Place the panels and slamming fixture in the cold box for 3 h at - 23 +/-1 C or at the temperature indicated in the specification requirements. 10

13、. Insert each panel in the test fixture (deadener or undercoating side out) and allow panel to fall from a horizontal position 6 times in rapid succession with no rebound between slams. Remove any loose particles of test material with the finger tips. FORD LABORATORY TEST METHOD BV 101-01 Page 3 of

14、4 Copyright 2000, Ford Global Technologies, Inc. 11. The panels are then given 5 additional cycles of testing. Each cycle constitutes the following: (a) Allow to come to 23 +/- 2 C and hold at this temperature for an additional 2 h. (b) 3 h minimum in the cold box at 23 +/- 2 C or at temperature ind
