5、 3.6 EVAPORATION After dipping a rubber test slab of approximately 115 mm by 30 mm in the uncut solution to a depth of 35 mm, it shall be held vertical for 10 minutes, then placed horizontally for 20 minutes. It shall retain a water wet surface for 15 minutes, and after 20 minutes remain partially t

6、ransferable (without rubbing) to a blotter or standard paper hand towel. The untouched portion of the panel shall retain all its lubricity as the evaporation proceeds for the next 30 minutes. After 4 hours, the material shall be dry; that is, completely non-transferable to a blotter or standard pape

7、r hand towel when placed in contact with the material without rubbing. 3.7 SHELF LIFE Shall maintain its properties for a period of 1 year when stored in the original, sealed container under ambient conditions.

Strips

10、 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 to prevent evaporation, supported in a beaker, and then placed in an oven at 70 +/- 2 C for 70 h. The strips shall be examined under magnification

12、re: Two rubber test slabs shall be prepared from 60 durometer, 6 mm, SBR rubber sheet, which conforms to compositions agreed upon between supplier and Ford Motor Company. The rubber test slabs shall be 76 mm by 100 mm with a 3 mm diameter hole centered on a line 6 mm from one end. An additional stee

13、l 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 slab and the steel panels shall be thoroughly cleaned with water. A thin layer of lubricant shall then be applied to one surface of both the steel test panel and the

14、rubber test slab. The steel test panels shall be clamped, lubricated side up, in a stationary 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 b

15、e placed unlubricated on the top of the rubber test slab. A standard kilogram weight shall be 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

16、placed that the cord is held horizontally in line with the rubber test slab between the slab and 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 ENGINEE

17、RING MATERIAL SPECIFICATION WSS-M99B186-A Copyright 2017, Ford Global Technologies, LLC Page 3 of 4 increases greater than 10 g per second, until the rubber test slab begins to slide. The coefficient of friction shall be calculated using the following formula: U = F/N Where F=Weight required to move

18、 one surface over the other U=Coefficient of static friction N=Total weight pressing the surfaces together 4.6.2 Dry 0.5 min After rubber slab has been prepared according to para 4.6.1, allow to dry for 48 h prior to testing in a humidity of approximately 50 +/- 10% at 23 +/- 2 C. 4.7 WETTING Shall

19、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 retention of lubricant as described i

20、n para 3.6 and exhibit no voids or dry spots. 4.8 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 to thaw without any physical agitation

21、. Upon complete thawing, the material shall exhibit no evidence of separation or precipitation. 4.9 CHEMICAL ATTACK TO PAINTED SURFACES (FLTM BI 168-01, Methods A & B) 4.10 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasi

22、ng, Design or Product Development, and Materials Engineering. The supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of the Material Specification.

23、Tested material samples must be available for review upon request and kept for a minimum of one year. Upon request, the supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing) with Ford. 4.11 SUPPLIERS ONGOING RE

24、SPONSIBILITY All materials must be equivalent in all characteristics to the material upon which approval was originally granted.
