Summary of Test Method3.1 A mixture of 300 mL of the oil under test is stirred with30 mL
10、of distilled water or synthetic sea water, as required, ata temperature of 60 6 1C (140 6 2F) with a cylindrical steeltest rod completely immersed therein. It is recommended to runthe test for 4 h; however, the test period may, at the discretionof the contracting parties, be for a shorter or longer
11、period. Thetest rod is observed for signs of rusting and, if desired, degreeof rusting.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products and Lubricants and is the direct responsibility of SubcommitteeD02.C0 on Turbine Oils.Current edition approved May 1, 2006.

16、icance and Use4.1 In many instances, such as in the gears of a steamturbine, water can become mixed with the lubricant, andrusting of ferrous parts can occur. This test indicates how wellinhibited mineral oils aid in preventing this type of rusting.This test method is also used for testing hydraulic
17、 andcirculating oils, including heavier-than-water fluids. It is usedfor specification of new oils and monitoring of in-service oils.NOTE 3This test method was used as a basis for Test Method D 3603.Test Method D 3603 is used to test the oil on separate horizontal andvertical test rod surfaces, and
18、can provide a more discriminating evalua-tion.5. Apparatus5.1 Oil BathA thermostatically controlled liquid bathcapable of maintaining the test sample at a temperature of 606 1C (140 6 2F) (see Note 4).

40、 specified in Section 8.7. Sampling7.1 Sample for this test can come from tanks, drums, smallcontainers, or even operating equipment, and they should betruly representative of the entire quantity. Therefore, use theapplicable apparatus and techniques described in PracticeD 4057, or other comparable
41、standard practice.8. Test Rod and Its Preparation8.1 For each test oil, prepare two steel test rods. These mayeither 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 testrod fitted to a plastic ho
42、lder. The round steel test rod, whennew, shall be 12.7 mm (0.5 in.) in diameter and approximately68 mm (21116 in.) in length exclusive of the threaded portionwhich screws into the plastic holder and shall be tapered at oneend as shown in Fig. 3. It shall be made of steel conforming toGrade 10180 of
43、Specification A 108 or to BS 970 Part I:1983-070M20. If these steels are not available, other equiva-lent steels may be used, provided they are found to besatisfactory by comparative test using this Test MethodD 665 IP 135.NOTE 9When making a check test, the steel test rod that showed rustshould not
44、 be reused. Test rods that repeatedly show rust in tests of variousoils can be imperfect. Such test rods should be used with oils known topass the test. If rusting occurs in repeat tests, these test rods should bediscarded.8.3 Preliminary GrindingIf the test rod has been usedpreviously and is free o
45、f rust or other irregularities, thepreliminary grinding may be omitted, and it may be subjectedonly to final polishing as prescribed in 8.4. If the test rod is newor if any part of its surface shows rust or other irregularities,clean it with ASTM precipitation naphtha or isooctane or IP60/80 petrole
46、um spirit and grind with medium 150-grit alumi-num oxide cloth to remove all irregularities, pits, and scratches,as determined by visual inspection (Note 10). Perform thegrindings by mounting the test rod in the chuck of the grindingand polishing apparatus, and turning it at a speed of 1700 to1800 r
47、pm while applying the 150-grit aluminum oxide cloth.Old 150-grit aluminum oxide cloth may be used to remove rustor major irregularities, but complete the grinding with newcloth. Proceed at once with the final polishing with 240-gritaluminum oxide cloth, or remove the test rod from the chuckand store
48、 in isooctane until needed. Discard reused test rodswhen the diameter is reduced to 9.5 mm (0.375 in.).NOTE 10Do not touch the test rods with the hands at any stage aftercleaning with naphtha or isooctane or the petroleum spirit (which precedeseither preliminary grinding or final polishing) until th
49、e test is completed.Forceps or a clean, lintless cloth may be used.8.4 Final Polishing:8.4.1 Just before the test is to be made, subject the test rodto final polishing with 240-grit aluminum oxide cloth. If thepreliminary grinding has just been completed, stop the motor7Reagent Chemicals, American Chemical Society Specifications, AmericanChemical Society, Washington, DC.
