Причина отмены This specification covered lubricants intended for use in two-stroke-cycle spark-ignition gasoline engines, typically other than outboard motors, that are particularly prone to ring sticking, but which are also liable to suffer damage arising from deposit induced preignition, piston scuff, spark plug fouling and piston varnish.

Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this specification was withdrawn in January 2022 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Реферат

This specification covers lubricants for two-stroke-cycle spark-ignition gasoline engines that are prone to ring sticking and damage caused by deposit-induced preignition, piston scuff, spark plug fouling, and piston varnish. The engine oils should be tested for performance, ring sticking and piston deposit, lubricity, and preignition.

1.1 This specification covers lubricants intended for use in two-stroke-cycle spark-ignition gasoline engines, typically other than outboard motors, that are particularly prone to ring sticking, but which are also liable to suffer damage arising from deposit induced preignition, piston scuff, spark plug fouling and piston varnish.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
