\n Significance and Use <\/b><\/p>\n

This is an accelerated engine oil test, performed in a standardized, calibrated, stationary single-cylinder diesel engine that gives a measure of ( 1 <\/span> ) piston and ring groove deposit forming tendency, ( 2 <\/span> ) piston, ring and liner scuffing and ( 3 <\/span> ) oil consumption. The test is used in the establishment of diesel engine oil specification requirements as cited in Specification D4485<\/span> for appropriate API Performance Category C oils (API 1509). The test method can also be used in diesel engine oil development.<\/p>\n

1. Scope <\/b><\/p>\n

1.1 This test method covers and is required to evaluate the performance of engine oils intended to satisfy certain American Petroleum Institute (API) C service categories (included in Specification D4485<\/span> ). It is performed in a laboratory using a standardized high-speed, single-cylinder diesel engine. Piston and ring groove deposit-forming tendency and oil consumption is measured. The piston, the rings, and the liner are also examined for distress and the rings for mobility.<\/p>\n

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.2.1 Exceptions <\/span> \u2014 <\/span> Where there is no direct SI equivalent such as screw threads, National Pipe Threads\/diameters, tubing size, or where there is a sole source supply equipment specification.<\/p>\n

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. Being an engine test method, this standard does have definite hazards that require safe practices (see Appendix X2 on Safety). <\/span> <\/span><\/p>\n
