15、-2959. United States14. Significance and Use4.1 Horizontal metal surfaces, on which water droplets tend to be retained, are more prone to rusting and corrosion than verticalor sloping surfaces. This test method is therefore more discriminating than Test Method D665 (Procedure A), since it gives asep

16、arate evaluation of the oil on a horizontal and a vertical surface. The test method indicates the ability of oils to prevent rustingand corrosion of all ferrous surfaces in steam turbines under full flow and quasi-static conditions. It is used for specification of newoils.5. Apparatus5.1 Oil BathA t

17、hermostatically controlled liquid bath capable of maintaining a temperature in the oil sample of 6060 C 61C (1401 C (140 F 6 2F).2 F). The bath shall have a cover with holes to accommodate the test beakers.NOTE 1The bath used for Test Method D665 may be used with slight modification, that is, the ce

18、nters of the beaker holes are moved from 6.4 mmto 18.3 mm 6.4 mm to 18.3 mm (14 in. to 2332 in.) in.) from the axes of the stirrers.NOTE 2To indicate the temperature, a thermometer conforming to the requirements of ASTM Thermometer 9C or 9F, or IP Thermometer 21C, asprescribed in Specification E1 sh

19、ould be used. Thermometric devices such as RTDs, themistors, thermocouples, or a thermometer conforming toSpecification E2251 may be used.NOTE 3Thermometer S130C (S130F) in Specification E2251 may be suitable. Temperature range: 7 C to 105 C and scale error, max.: 0.5 C ascompared to Thermometer 9C

20、with a temperature range of 5 C to 110 C and a scale error, max of 0.5 C.5.2 BeakerA400-mL,400 mL, Berzelius-type, tall-form heat-resistant glass (see Note 4) beaker without pourout, as shown inFig. 1, approximately 127 mm (5 in.) 127 mm (5 in.) in height measured from the inside bottom center and a

21、pproximately 70 mm70 mm (234 in.) in.) in inside diameter measured at the middle.NOTE 4Borosilicate glass is satisfactory for this purpose.5.3 Beaker Cover and Specimen HolderA flat beaker cover (Fig. 2) of methyl methacrylate resin or other fluid resistantmaterial is kept in position by a suitable

22、groove. Three holes are provided. Two are located on any diameter of the cover, one fora stirrer, and the other for attachment of a disk specimen to the underside of the cover for optional vapor phase testing. The thirdhole is for a thermometer, located on a diameter perpendicular to that of the oth

23、er two holes. The outside of thepolytetrafluoroethylene (PTFE) specimen holder (Fig. 3) is a square, but from the ends of one diagonal, two equal pieces of PTFEare cut off over the height of the holder. Two vertical threaded holes are made on the other diagonal of the square. The inside ofthe holder

24、 consists of two cylindrical holes, one on top of the other. Four horizontal holes are drilled 90 apart on the circumferencewhere the two cylindrical holes meet. The PTFE specimen holder is connected to the beaker cover by two stainless steel holdingrods (Fig. 4). Both ends of each holding rod are t

25、hreaded. The surfaces between the threads are polished with No. 180 P180 (180)grit emery. The 12.7-mm12.7 mm threaded ends of the holding rods are screwed into the two vertical threaded holes of thespecimen holder. The 19.0-mm19.0 mm threaded ends of the holding rods are connected to the beaker cove

26、r by putting themthrough two holes on a line perpendicular to the connection line of the centers of the earlier mentioned first and second hole ofthe beaker cover. Each holding rod is fastened by two 10-32 stainless steel nuts.NOTE 5An alternative design for the specimen holder assembly has also bee

27、n used successfully.

29、od 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 ASTM Specification A240/A240M or SAE No.30304, or BS 970: Part I:1983:302531.NOTE 7If stainless steel is not obtainable, stirrers made of heat-resistant g

30、lass (Note 4) and having approximately the same dimensions as the stainlesssteel stirrers may be used.NOTE 1All dimensions are in millimetres (inches).NOTE 2Unless otherwise specified, tolerances will be 60.5 60.02.NOTE 3No direct equivalent available for #9 drill in metric system.FIG. 2 Beaker Cove
