1、Designation: D3603 14Standard Test Method forRust-Preventing Characteristics of Steam Turbine Oil in thePresence of Water (Horizontal Disk Method)1This standard is issued under the fixed designation D3603; the number immediately following the designation indicates the year oforiginal adoption or, in

2、 the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This test method covers the ability of steam-turbine oilsto prevent the rusting of

3、 horizontal and vertical ferrous surfaceswhen water becomes mixed with the oil.1.2 The values stated in SI units are to be regarded asstandard. The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its

4、 use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

8、s3. Summary of Test Method3.1 The test method involves completely immersing a hori-zontal steel disk and vertical steel cylinder in a stirred mixtureof 275 mL of the oil under test and 25 mL of distilled water(water conforming to Specification D1193, Type II) at atemperature at 60 C (140 F).3.2 The

9、horizontal specimen allows water to puddle on thesurface, and the vertical specimen is continually washed withthe oil-water mixture during the test.3.3 The test is run for 6 h and the specimens are evaluated.4. Significance and Use4.1 Horizontal metal surfaces, on which water droplets tendto be reta

10、ined, are more prone to rusting and corrosion thanvertical or sloping surfaces. This test method is therefore morediscriminating than Test Method D665 (Procedure A), since itgives a separate evaluation of the oil on a horizontal and avertical surface. The test method indicates the ability of oils to

11、prevent rusting and corrosion of all ferrous surfaces in steamturbines under full flow and quasi-static conditions. It is usedfor specification of new oils.5.

19、) in inside diameter measured at the middle.NOTE 4Borosilicate glass is satisfactory for this purpose.5.3 Beaker Cover and Specimen HolderA flat beakercover (Fig. 2) of methyl methacrylate resin or other fluidresistant material is kept in position by a suitable groove. Threeholes are provided. Two a

The third hole is for a thermometer, located on adiameter perpendicular to that of the other two holes. Theoutside of the polytetra

21、fluoroethylene (PTFE) specimen holder(Fig. 3) is a square, but from the ends of one diagonal, twoequal pieces of PTFE are cut off over the height of the holder.Two vertical threaded holes are made on the other diagonal ofthe square. The inside of the holder consists of two cylindricalholes, one on t

22、op of the other. Four horizontal holes are drilled90 apart on the circumference where the two cylindrical holesmeet. The PTFE specimen holder is connected to the beakercover by two stainless steel holding rods (Fig. 4). Both ends ofeach holding rod are threaded. The surfaces between thethreads are p

23、olished with No. P180 (180) grit emery. The12.7 mm threaded ends of the holding rods are screwed into thetwo vertical threaded holes of the specimen holder. The19.0 mm threaded ends of the holding rods are connected to thebeaker cover by putting them through two holes on a lineperpendicular to the c
