ASTM D4684-07 低温下发动机油的屈服应力和表观粘度用标准试验方法

1.1 This test method covers the measurement of the yield stress and viscosity of engine oils after cooling at controlled rates over a period exceeding 45 h to a final test temperature between -10 and -40176;C. The viscosity measurements are made at a shear stress of 525 Pa over a shear rate of 0.4 to 15 s-1. The viscosity as measured at this shear stress was found to produce the best correlation between the temperature at which the viscosity reached a critical value and borderline pumping failure temperature in engines.1.2 Procedure A of this test method has precision stated for a yield range from less than 35 Pa to 210 Pa and apparent viscosity range from 4300 to 270 000 mPas. The test procedure can determine higher yield stress and viscosity levels.1.3 This test method is applicable for unused oils, sometimes referred to as fresh oils, designed for both light duty and heavy duty engine applications. It also has been shown to be suitable for used diesel and gasoline engine oils. The applicability to petroleum products other than engine oils has not been determined.1.4 This test method uses the milliPascal second (m956;Pas) as the unit of viscosity. For information, the equivalent unit, centiPoise (cP), is shown in parentheses.1.5 This test method contain two procedures: Procedure A incorporates several equipment and procedural modifications from Test Method D 4684-02 that have shown to improve the precision of the test, while Procedure B is unchanged from Test Method D 4684-02. Additionally, Procedure A applies to those instruments that utilize thermoelectric cooling technology and those that use indirect refrigeration technology of recent manufacture for instrument temperature control. Procedure B can use the same instruments used in Procedure A or those cooled by circulating methanol.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Determining the Leakage Tendencies of Automotive Wheel Bearing Grease Under Accelerated Conditions

ASTM D2982-07 检测已用润滑油中乙二醇基防冻剂的标准试验方法

Leakage of glycol-base antifreeze into the crankcase is serious because the coolant tends to interfere with the lubricant and its ability to lubricate; it also promotes sludging. Ethylene glycol present in the coolant can increase varnish deposit formation in the crankcase as a result of glycol oxidation and the interaction between glycol and lubricant. Furthermore, because glycol is a higher boiling material than water, it will tend to stay longer in the crankcase oil than water. Lubricant displacement, sludging, and deposit formation all lead to engine malfunction and possible seizure. These tests are designed to detect glycol-base coolant contamination even at low levels because early detection enables corrective measures to be taken to prevent leaking coolant from accumulating and seriously damaging the engine. These test methods are also significant because the reagents can be packaged as a field kit, and the procedure can be followed at the site where there is a concern.1.1 These test methods cover the qualitative determination of glycol-base antifreeze in used lubricating oils (mineral base) by two procedures, one using reagents in tablet form and the other using laboratory shelf reagents. Principally the test methods detect ethylene glycol but will also detect other 1,2-glycols that may be present. 1.1.1 When a positive result is obtained and a sample of the unused oil is available, the unused oil is also tested and used as a reference. Note 18212;Since the inception of this test method (1971), there have been many changes in base stock technology and additive technology. Therefore, when available, the new, unused oil, or a sample of the same used oil, known to not contain antifreeze, is tested as a reference. 1.2 The tablet procedure (Procedure A) is sensitive to about 100 mg/kg and the shelf reagent procedure (Procedure B) to about 300 mg/kg of ethylene glycol. 1.3 Glycol-based coolant leaks into crankcases may not be detected or may result in a low bias using these test methods if the glycol has degraded or been thermally or otherwise oxidized. The conditions in crankcases may be such that contaminant glycols are oxidized or degraded to a degree to which the color indicator reaction does not occur or is biased enough so as to not trigger the color change. Other test methods for the detection of coolants or coolant additives in lubricating oils should be used if the results from these test methods alone are inconclusive or questionable. 1.4 Carbohydrates such as sugars and sugar-containing substances are sometimes used for sabotage purposes. If the presence of these substances is suspected, Procedure A contains a modification to remove these interferences. 1.5 Both procedures are adaptable to field kit use, and brief descriptions for converting to field kit form are given in Annex A1. Commercial field testing kits are available. , 1.6 The results obtained by this method are qualitative expressions. However, for the preparation of reagents and in the procedures, acceptable SI units are to be regarded as the standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This test is used for specification purposes and correlates with its precursor which has been used to predict the performance of greases in automotive wheel bearings in low-temperature service. It is the responsibility of the user to determine the correlation with other types of service.1.1 This test method covers the determination of the extent to which a test grease retards the rotation of a specially-manufactured, spring-loaded, automotive-type wheel bearing assembly when subjected to low temperatures. Torque values, calculated from restraining-force determinations, are a measure of the viscous resistance of the grease. This test method was developed with greases giving torques of less than 35 N·m at −40°C. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 WARNINGMercury has been designated by many regulatory agencies as a hazardous material that can cause central nervous system, kidney and liver damage.

ASTM D3603-07 有水的情况下蒸汽涡轮机油的防锈特性用标准试验方法(水平圆盘法)

Horizontal metal surfaces, on which water droplets tend to be retained, are more prone to rusting and corrosion than vertical or sloping surfaces. This test method is therefore more discriminating than Test Method D 665 (Procedure A), since it gives a separate evaluation of the oil on a horizontal and a vertical surface. The test method indicates the ability of oils to prevent rusting and corrosion of all ferrous surfaces in steam turbines under full flow and quasi-static conditions. It is used for specification of new oils.1.1 This test method covers the ability of steam-turbine oils to prevent the rusting of horizontal and vertical ferrous surfaces when water becomes mixed with the oil.1.2 The values stated in SI units are to be regarded as the standard.

The PAI is representative of the quantity of all the compounds containing a carbonyl function that have formed by the oxidation of the lubricant (aldehydes, ketones, carboxylic acids, esters, anhydrides, etc.). The PAI gives representative information on the chemical degradation of the lubricant which has been caused by oxidation. This test method was developed for transmission oils and is used in the CEC L-48-A-00 test (Oxidation Stability of Lubricating Oils Used in Automotive Transmissions by Artificial Aging) as a parameter for the end of test evaluation.1.1 This test method covers the determination of the oxidation of used lubricants by FT-IR (Fourier Transform Infrared Spectroscopy). It measures the concentration change of constituents containing a carbonyl function that have formed during the oxidation of the lubricant.1.2 This test method may be used to indicate relative changes that occur in an oil under oxidizing conditions. The test method is not intended to measure an absolute oxidation property that can be used to predict performance of an oil in service.1.3 This test method was developed for transmission oils which have been degraded either in service, or in a laboratory test, for example a bulk oxidation test. It may be used for other in-service oils, but the stated precision may not apply.1.4 The results of this test method may be affected by the presence of other components with an absorbance band in the zone of 1600-1800 cm-1.

Standard Test Method for Life Performance of Automotive Wheel Bearing Grease

ASTM D1478-07 滚珠轴承润滑脂的低温扭矩用标准试验方法

This test method was developed using greases having very low torque characteristics at −54°C (−65°F). Specifications for greases of this type commonly require testing at this temperature. Specifications for greases of other types can require testing at temperatures from −75 to −20°C (−100 to 0°F). This test method has proved helpful in the selection of greases for low-powered mechanisms, such as instrument bearings used in aerospace applications. The suitability of this test method for other applications requiring different greases, speeds, and temperatures should be determined on an individual basis. Test Method D 4693 may be better suited for applications using larger bearings or greater loads. However, greases having such characteristics that permit torque evaluations by either this test method or Test Method D 4693 will not give the same values in the two test methods (even when converted to the same torque units) because the apparatus and test bearings are different. FIG. 1 Torque Test Apparatus Assembly FIG. 2 Drive (Top View)1.1 This test method covers the determination of the extent to which a grease retards the rotation of a slow-speed ball bearing by measuring starting and running torques at low temperatures (below -20176;C (0176;F)).1.1.1 Torque measurements are limited by the capacity of the torque-measuring equipment. Note 1 - When initially developed, the original dynamometer scale limited the torque capacity to approximately 30 000 gcm; the original dynamometer scale is obsolete, however. The suggested replacement scale has not been evaluated; it could extend the limit to approximately 75 000 gcm.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. The exception is torque values that are given in cgs-metric units, which are universally used in grease specification.This standard does not purport to address all of the safety concerns, if any, associated with its use.
