Cockman Application This method is used to determine the resistance to emulsification with water of turbine, hydraulic and quenching oils.
2、Apparatus and Materials Required (See Sketch) Graduated Measuring Cylinder 250 mL, approx 40 mm dia, heat resistant, tall form, with round bottom (A). Delivery Tube Glass, 7 mm inner dia (B) 60“ angle on the immersed end (H). Distillation Flask 1 O00 mL, coppedpyrex (C) or equivalent. Column 7 mm in
3、ner dia, approx 1 m in length (D). Retort Stands and Clamps (F) Bunsen Burner (G) Demineralised Water Chromic Acid Acetone Stop Watch 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
4、humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Copynght02001, Ford Global Technologies, Inc FORD LABORATORY TEST METHOD EU-BJ 002-01 Procedure 1. Clean the measuring cylinder and glass tubing first with acetone and then with chromic
5、acid and rinse free of acid with demineralised water. 2. Pour 50 mL of demineralised water and 1 O0 mL of the oil under test into the measuring cylinder and heat in a water bath at a temperature of 1 O0 OC for 1 O minutes. 3. After removing, clamp the measuring cylinder on the retort stand and immer
6、se the glass tubing (B) into the water and pass steam for a period of 1 O minutes. 4. Remove the glass tubing and again heat the measuring cylinder in the water bath at a temperature of 100 OC for another 10 minutes. Evaluation Immediately after removal from the water bath, examine and record as fol
