Summary of Test Method3.1 A mixture of 300 mL of the oil under test is stirred with 30 mL of distilled water or synthetic sea water, as required, at atemperature of 60 6 1C (140 6 2F) with a cylindrical steel test rod completely immersed therein. It is recommended to

18、run thetest for 4 h; however, the test period may, at the discretion of the contracting parties, be for a shorter or longer period. The testrod is observed 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 compariso

19、ns of different test times showed that no statisticallysignificant differences in rating were found for any sample, between the 4 and 24 h results.64. Significance and Use4.1 In many instances, such as in the gears of a steam turbine, water can become mixed with the lubricant, and rusting of ferrous

20、parts can occur. This test indicates how well inhibited mineral oils aid in preventing this type of rusting. This test method is alsoused for testing hydraulic and circulating oils, including heavier-than-water fluids. It is used for specification of new oils andmonitoring of in-service oils.NOTE 3T

21、his 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 surfaces, and can provide a more discriminating evaluation.5. Apparatus5.1 Oil BathA thermostatically controlled liquid bath capable of maintaining the tes

22、t sample at a temperature of 60 6 1C(140 6 2F) (see Note 4). An oil having a viscosity of approximately ISO VG 32 (see Classification D2422) is suitable for thebath. The bath shall have a cover with holes to accommodate the test beakers.NOTE 4ASTM Thermometer 9C (9F), 9C, as prescribed in Specificat

23、ion E1, or IP Thermometer 21C in accordance with IP Standard Thermometers,Volume 2, Appendix A, is suitable to indicate the temperature. Alternatively, calibrated thermocouples may be used.5.2 BeakerA400-mL, Berzelius-type, tall-form heat-resistant glass beaker without pourout, as shown in Fig. 1, a

25、roove. Two holes shall be provided on any diameter of the cover; one for a stirrer 12 mm (1532 in.) indiameter with its center 6.4 mm (14 in.) from the center of the cover; and the other, on the opposite side of the center of the cover,for the test rod assembly (see Section 8), 18 mm (4564 in.) in d

26、iameter with its center 16 mm (58 in.) from the center of the cover.In addition, a third hole 12 mm (1532 in.) in diameter shall be provided for a temperature measuring device, with its center 22.5mm (78 in.) from the center of the cover and on a diameter of the cover at right angles to the diameter

Fig. 2 shows a PMMA resin cover forthe beaker which has been found to be suitable. An optional feature is shown, consisting of a slot, 1.6 by 27 mm (mm, 116 by 11

28、16 in.), which is centeredon a diameter of the stirrer hole at right angles to the cover diameter through the test rod hole and stirrer hole. This feature allows withdrawal of the stirrerwhile the beaker cover is in place. When the test method test is used for other fluids such as synthetics, the be

29、aker cover should be made from chemicallyresistant material such as polymonochlorotrifluoroethylene (PCTFE).5.4 The plastic holder shall be made of PMMA resin in accordance with the dimensions shown in Fig. 3 (two types of holdersare illustrated). When testing synthetic fluids, the plastic holder sh

30、ould be made from chemically resistant material such aspolytetrafluoroethylene (PTFE).5.5 StirrerA stirrer constructed entirely from stainless steel (Note 6 and Note 7) in the form of an inverted T. A flat blade 25by 6 by 0.6 mm (1 by 0.24 by 0.024 in.) shall be attached to a 6-mm (0.24-in.) rod in

31、such a way that the blade is symmetricalwith the rod and has its flat surface in the vertical plane.NOTE 6A suitable material is an 18 % chromium, 8 % nickel alloy steel conforming to Type 304, of Specification A240/A240M, or SAE No. 30304(see SAE J405), or BS 970: Part 1: 1983: 302S31.NOTE 7If stai

32、nless steel is not obtainable, stirrers made of heat-resistant glass and having approximately the same dimensions as the stainless steelstirrers specified can be used.5.6 Stirring ApparatusAny convenient form of stirring apparatus capable of maintaining a speed of 1000 6 50 rpm.5.7 Grinding and Poli

45、.7 Steel Test Rod, as specified in Section 8.7. Sampling7.1 Sample for this test can come from tanks, drums, small containers, or even operating equipment, and they should be trulyrepresentative of the entire quantity. Therefore, use the applicable apparatus and techniques described in Practice D405

These may either be new or from a previous test (see Note 9) and shall beprepared in accordance with 8.2 and 8.3.8.2 The test rod assembly shall consist of a round steel test ro

47、d fitted to a plastic holder. The round steel test rod, when new,shall be 12.7 mm (0.5 in.) in diameter and approximately 68 mm (21116 in.) in length exclusive of the threaded portion whichscrews into the plastic holder and shall be tapered at one end as shown in Fig. 3. It shall be made of steel co

48、nforming to GradeD665 12610180 of Specification A108 or to BS 970 Part I: 1983-070M20. If these steels are not available, other equivalent steels may beused, provided they are found to be satisfactory by comparative test using this Test Method D665 IP 135.NOTE 9When making a check test, the steel te

49、st rod that showed rust should not be reused. Test rods that repeatedly show rust in tests of variousoils can be imperfect. Such test rods should be used with oils known to pass the test. If rusting occurs in repeat tests, these test rods should be discarded.8.3 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 8.4.
