1、Designation: D6923 10aD6923 13Standard Test Method forEvaluation of Engine Oils in a High Speed, Single-CylinderDiesel EngineCaterpillar 1R Test Procedure1This standard is issued under the fixed designation D6923; the number immediately following the designation indicates the year oforiginal adoptio

2、n or, in 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.INTRODUCTIONAny properly equipped laboratory, without outside assistance, can use the t

3、est procedure describedin this test method. The ASTM Test Monitoring Center (TMC)2 provides calibration oils and anassessment of the test results obtained on those oils by the laboratory. By this means, the laboratorywill know whether their use of the test method gives results statistically similar

4、to those obtained byother laboratories. Furthermore, various agencies require that a laboratory utilize the TMC services inseeking qualification of oils against specifications. For example, the U.S.Army has such a requirementin some of its engine oil specifications. Accordingly, this test method is

5、written for those laboratoriesthat use the TMC services. Laboratories that choose not to use these services should ignore thoseportions of the test method that refer to the TMC. Information Letters issued periodically by the TMCmay modify this test method.3 In addition, the TMC may issue supplementa

6、ry memoranda related tothe test method.1. Scope Scope*1.1 This test method covers stressing an engine oil under modern high-speed diesel operating conditions and measures the oilsdeposit control, lubrication ability, and resistance to oil consumption. It is performed in a laboratory using a standard

7、izedhigh-speed, single-cylinder diesel engine.41.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.2.1 ExceptionsWhere there is no direct SI equivalent such as screw threads, national pipe threads/diameters, and tubing size,

8、or where a sole source supplier is specified.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulat

9、oryrequirements prior to use. Being an engine test method, this test method does have definite hazards that require safe practices (seeAppendix X2 on Safety).1.4 The following is the Table of Contents:Scope 1Referenced Documents 2Terminology 3Summary of Test Method 4Significance and Use 5Apparatus a
