Description

ASTM D6750-04

Historical Standard: 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)

ASTM D6750

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 ).

1.3 The values stated in inch-pound units or SI units are to be regarded separately as standard. When inch-pound units are standard, the SI units are shown in parenthesis. The values stated in each system are not necessarily exact equivalents. Because of this, combining values from the two systems may be incompatible. Therefore, use either system independently of the other.

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. Specific precautionary statements are given within the text. Being engine tests, these test methods do have definite hazards which shall be met by safe practices (see on Safety).
