Organization: ASTM International
Publication Date: 10 August 2001
Status: inactive
Page Count: 53
ICS Code (Lubricants, industrial oils and related products): 75.100
scope:

1.1 This test method is used to evaluate automotive engine oils (SAE grades 5W, 10W, 20, 30, 40, and 50, and multiviscosity grades) intended for use in spark-ignition gasoline engines. The test procedure is conducted using a carbureted, spark-ignition Cooperative Lubrication Research (CLR) Oil Test Engine (also referred to as the Sequence VIII test engine in this test method) run on unleaded fuel. An oil is evaluated for its ability to protect the engine and the oil from deterioration under high-temperature and severe service conditions. The test method can also be used to evaluate the viscosity stability of multiviscosity-graded oils. Companion test methods used to evaluate engine oil performance for specification requirements are discussed in the latest revision of Specification D4485.

1.2 Correlation of test results with those obtained in automotive service has not been established. Furthermore, the results obtained in this test are not necessarily indicative of results that will be obtained in a full-scale automotive spark-ignition or compression-ignition engine, or in an engine operated under conditions different from those of the test. The test can be used to compare one oil with another.

1.3 The values stated in SI units are to be regarded as standard, except for (1) volume which is given in the metric, but non-SI, litre, (2) certain tube measurements which are given in the inch-pound unit, (3) cylinder bore and stroke in both SI and inch-pound units (the inch-pound being the standard) and (4) piston displacement given in metric (non-SI) and inch-pound unit (the inch-pound being the standard). In respect to (3) and (4) the inch-pound units are shown first and the SI units in parenthesis.

1.4 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 provided throughout this test method.
