(Test Method)Standard Test Methods for Evaluation of Engine Oils in a High-Speed, Single-Cylinder Diesel Engine-1K Procedure (0.4 % Fuel Sulfur) and 1N Procedure (0.04 % Fuel Sulfur)
Standard Test Methods for Evaluation of Engine Oils in a High-Speed, Single-Cylinder Diesel Engine-1K Procedure (0.4 % Fuel Sulfur) and 1N Procedure (0.04 % Fuel Sulfur)
SCOPE
1.1 These test methods cover the performance of engine oils intended for use in certain diesel engines. They are performed in a standardized high-speed, single-cylinder diesel engine by either the 1K (0.4 % fuel sulfur) or 1N (0.04 % fuel sulfur) procedure. The only difference in the two test methods is the fuel used. Piston and ring groove deposit-forming tendency and oil consumption are measured. Also, the piston, the rings, and the liner are examined for distress and the rings for mobility. These test methods are required to evaluate oils intended to satisfy API service categories CF-4 and CH-4 for 1K, and CG-4 for 1N of Specification D 4485.
1.2 These test methods, although based on the original Caterpillar 1K/1N procedures, also embody TMC information letters issued before these test methods were first published. These test methods are subject to frequent change. Until the next revision of these test methods, TMC will update changes in these test methods by the issuance of information letters which shall be obtained from TMC (see Annex A15).
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therfore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4This 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.Specific precautionary statements appear throughout the text. Being engine tests, these test methods do have definite hazards that shall be met by safe practices (see Annex A16 on Safety Precautions).

The test methods described in this standard can be used by any properly equipped laboratory

without outside assistance. However, the ASTM Test Monitoring Center (TMC) provides reference

uses the TMC services in seeking qualification of oils against specifications. For example, the U.S.
Army has such a requirement in some of its engine oil specifications.
Accordingly, these test methods are written for those laboratories that use the TMC services.
Laboratories that choose not to use these services may ignore those portions of the test methods that
refer to the TMC.
These test methods may be modified by Information Letters issued periodically by the TMC after
the publication of this edition of the standard to become part of it. These letters are obtainable from
