5、PECIFICATION ESA-M1B14-A Page 2 of 3 Copyright 2002, Ford Global Technologies, Inc. 3.10 CORROSION Ford Motor Company, at its option, may conduct corrosion testing on materials/parts supplied to this specification. No pitting, etching or visible corrosion on the surface of steel, brass, aluminum and
6、 tin plate. Test Method Clean 25 mm x 76 mm strips of metals to be tested. Strips shall be immersed one each in a 100 mL test tube containing 15 mL of lubricant test sample. The test tube shall be lightly stoppered with a cork stopper, supported in a beaker, then placed in an oven at 70 +/- 2 C for
7、70 h. The strips shall be examined under magnification of 20 diameters for evidence of corrosion. 3.11 COEFFICIENT OF STATIC FRICTION TEST 3.11.1 Wet, max 0.3 Test Procedure: A rubber test slab shall be prepared from ounplasticized natural rubber sheet which conforms to compositions agreed upon betw
8、een supplier and Ford Motor Company. The rubber test slab shall be 76 mm by 100 mm with a 3 mm diameter hole centered on a line 6 mm from one end. An additional steel test panel 152 mm by 152 mm by 1 mm (Parker or Q-panel-unpolished) shall be used as bottom plate for the test. Both the rubber test s
9、lab and the steel panels shall be thoroughly cleaned with water and given a rinse with isopropyl alcohol. A thin layer of lubricant shall then be applied to one surface of both the steel test panel and the rubber test slab. The steel test panels shall be clamped, lubricated side up, in a stationary
10、position on a flat, horizontal surface and the rubber test slab shall be placed, lubricated side down, horizontally on the metal test panel. A steel plate, of known weight, measuring 75 mm by 100 mm shall be placed unlubricated on the top of the rubber test slab. A standard kilogram weight shall be
11、placed on top of, and centered on, the small steel plate. A cord of 305 mm to 610 mm in length is then attached through the hole in the rubber test slab. This cord shall be placed over a pulley which is so placed that the cord is held horizontally in line with the rubber test slab between the slab a
12、nd the pulley. The pulley shall be of such construction and so lubricated as to turn freely under load. Force (weight) shall then be applied to the free end of cord in small increments not to exceed increases greater than 10 g per second, until the rubber test slab begins to slide. The coefficient o
13、f friction shall be calculated using the following formula: U = F/N Where F=Weight required to move one surface over the other U=Coefficient of static friction N=Total weight pressing the surfaces together ENGINEERING MATERIAL SPECIFICATION ESA-M1B14-A Page 3 of 3 Copyright 2002, Ford Global Technol
14、ogies, Inc. 3.11.2 Dry, min 0.5 After rubber slab has been prepared according to para 3.11.1, allow to dry for 48 h prior to testing in a humidity of approximately 50 +/- 10 % at 23 +/- 2 C. 3.12 EVAPORATION After dipping a rubber test slab in the uncut solution, it shall be held vertical for 10 min
15、utes, then placed horizontal for the remainder of the test. It shall retain a water wet surface, and after 30 minutes remain readily transferable (without rubbing) to a blotter or standard paper hand towel. The untouched portion of the panel shall retain all its lubricity as the evaportion proceeds
16、for the next 30 minutes. After 48 hours the material shall be dry; that is, completely non-transferable to a blotter or standard paper hand towel when placed in contact with the material without rubbing. 3.13 FOAM Must not foam when sprayed on rubber any more than other materials approved under this
17、 specification. 3.14 WETTING Shall be applied from a spray nozzle positioned from 100 mm to 150 mm away from the panel and provide a fully wet surface. The panel shall be held vertical for 10 minutes and then placed horizontally for 20 minutes. At the end of this time, the panel shall exhibit the re
18、tention of lubricant as described in para 3.11 and exhibit no voids or dry spots. 3.15 FREEZE-THAW STABILITY Using a closed glass vessel, a sample of the uncut material shall be frozen over a 24 h period to complete solidification. The sample shall then be removed to a 23 C environment and allowed t
19、o thaw without any physical agitation. Upon complete thawing, the material shall exhibit no evidence of separation or precipitation. 4.
