1、FORD LABORATORY TEST METHOD BP 119-01 2001 O925 DETERMINATION OF THE ABRASION RESISTANCE OF ANTI-FRICTION COATINGS APPLIED TO DOOR SEALS AND SLIDING GLASS SEALS Revised Editorial - no technical change A. Cockman Application The two test procedures described are used to determine the abrasion resista
2、nce of anti-friction coatings applied to body closure seals and sliding glass seals. Method A determines the abrasion resistance in a “Slam“ mode and is applicable to body closure seals only. Method B determines the abrasion resistance in a sliding mode and is applicable to body closure and sliding
3、glass seals. Apparatus Required Slam Test Rig As shown schematically in Figure 1 capable of applying a vertical stroke of 75 +/- 5 mm to the test seal at a rate of 5 Hz to bring it into contact with the mounted painted panel at the specified compression as described in Method A. Vibration Test Rig A
4、s shown schematically in Figure 2 capable of applying a vertical stroke of 3 mm to the mounted painted test panel at a frequency of 4 to 17 Hz and allowing lateral adjustment of the seal to achieve the required compression as described in Method B. Conditioning and Test Conditions All test values in
5、dicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 OC and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. METHOD A: SLAM TEST Procedure Mount a steel panel, painted per FLTM BI
6、103-02, onto the movable platform of the Slam test rig and similarly mount a 50 mm length of seal under test onto the fixed platform of the test rig (see Figure 1). Adjust the height of the fixed platform so that the test seal is compressed at the end of the up-stroke by the amount specified on the

9、50mm length of seal under test onto the fixed platform of the test rig. (See Figure 2). Adjust the lateral position of the fixed platform until the test specimen has been compressed by 1 mm. Test the seal for the number cycles specified in the relevant Materials Specification or Engineering Drawing.
