Additional information

Significance and Use

This test method is primarily intended for the evaluation of lubricants for use in two-stroke-cycle engines of high specific output.

Note 1—If the test method is being used to satisfy a portion of Specification D 4859, refer to the specification for the pass-fail criteria.

1. Scope

1.1 This test method evaluates the performance of lubricants intended for use in two-stroke-cycle spark-ignition gasoline engines that are particularly prone to ring sticking. Piston varnish and spark plug fouling are also evaluated.

1.2 The values stated in SI units are the standard. The values given in parentheses are provided for information only.

1.3 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.
