Significance and Use | ||||||||||||||||||||||||||||||||
5.1 This test method is primarily intended for the evaluation of lubricants for use in two-stroke-cycle engines of high specific output. 1.1 This test method2 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 to be regarded as standard. No other units of measurement are included in this standard. 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. |
