Summary of Test Method4.1 A mixture of 300 mL of the oil under test is stirred with 30 mL of distilled water or sy

18、nthetic sea water, as required, at atemperature of 60 C 6 1C1 C with a cylindrical steel test rod completely immersed therein. It is recommended to run the testfor 4 h; however, the test period may, at the discretion of the contracting parties, be for a shorter or longer period. The test rodis obser

19、ved for signs of rusting and, if desired, degree of rusting.NOTE 2Until 1999 it was customary to run the test for 24 h. A round robin with comparisons of different test times showed that no statisticallysignificant differences in rating were found for any sample, between the 44 h and 24 h results.65

20、. Significance and Use5.1 In many instances, such as in the gears of a steam turbine, water can become mixed with the lubricant, and rusting of ferrousparts can occur. This test indicates how well inhibited mineral oils aid in preventing this type of rusting. This test method is alsoused for testing

21、 hydraulic and circulating oils, including heavier-than-water fluids. It is used for specification of new oils andmonitoring of in-service oils.NOTE 3This test method was used as a basis for Test Method D3603. Test Method D3603 is used to test the oil on separate horizontal and verticaltest rod surf

Apparatus6.1 Oil BathA thermostatically controlled liquid bath capable of maintaining the test sample at a temperature of 6060 C 61C1 C (see Note 4). An oil having a viscosity of approximately ISO VG 32 (see Classification D2422) is suitable

23、for the bath.The bath shall have a cover with holes to accommodate the test beakers.NOTE 4ASTM Thermometer 9C, as prescribed in Specification E1, or IP Thermometer 21C in accordance with IP Standard Thermometers, Volume2, Appendix A, is suitable to indicate the temperature. Alternatively, calibrated

If these steels are not available, other equivalent steels may be used, provided they arefound to be satisfactory by comparative test using this Test Method D665 IP 135.NOTE 9When making a check test, the steel test rod that showed rust should not be reused. Test rods tha

If rusting occurs in repeat tests, these test rods should be discarded.9.3 Preliminary GrindingIf the test rod has been used previously and is free of rust or other irregularities, the preliminarygrinding may be omitted, and it may be subjected only to final polishing as prescribed in 8.49.4. If the test rod is new or if anypart of its surface shows rust or other irregularities, clean it with ASTM pre
