2、rein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure 1. Set temperature regulator in test well to control the test lubricant
3、at 99 +/- 2 C. 2. Polish one SAE 1020 steel strip with sand paper for each lubricant to be tested (see figure 3). 3. Polish one standard Timken cup with sand paper for each lubricant to be tested and weigh. 4. Clean 500 mL beaker and weigh and add 200 mL of lubricant to be tested and weigh. 5. Add 2
4、0 % distilled water by weight to test lubricant. 6. Hang SAE 1020 strip on each beaker flange ring (see figure 1). 7. Place one Timken cup in the bottom of each test beaker. 8. Place the beaker containing the test oil and water into the well or wells of the oxidation test stand. Insert the stirring
5、 rod through the opening of the stainless steel condenser cover and set condenser on beaker ring flange, with steel strip. 9. Adjust water flow through the condenser cover to maintain a temperature below 38 C. FORD LABORATORY TEST METHOD BJ 110-03 Page 3 of 6 Copyright 2001, Ford Global Technologies
