Significance and Use | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
This test method was developed to evaluate diesel engine oils for protection against ring and liner distress caused by high thermal and mechanical loading. Liner scuffing and ring distress experienced in this test method are measures of the oil's ability to protect against scuffing and scoring under high power and high load conditions typical of service experienced by engines in use today. Piston pin slipper bushing wear, piston skirt tin removal, and liner port plugging are also examined in this test for distress which relates to overall engine life. This test method was developed to correlate with field experience using oils of known good and poor protection against ring and liner distress. The 6V92TA engine oil test is used in specifications and classifications of engine lubricating oils, such as the following: Specification D 4485, Military Specification MIL-L-2104, and SAE Classification J 183. |

1. Scope | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1.1 This test method describes a two-stroke cycle diesel engine test procedure for evaluating engine oils for certain high-temperature performance characteristics, particularly cylinder liner scuffing and piston ring face distress, but also including port plugging, slipper bushing, and piston skirt distress. Such oils include both single viscosity SAE grade and multiviscosity SAE grade oils used in diesel engines. It is commonly known as the 6V92TA test. (See Note 1.) Note 1—Companion test methods used to evaluate other engine oil performance characteristics for specification requirements are discussed in Engine Oil tests—SAE J304. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 Exceptions—Where there is no direct SI equivalent, such as screw threads, National Pipe Threads/diameters, tubing size, or single source supply equipment specifications. Also, many of the figures still show inch-pound units. 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. Specific hazard statements are given in Sections 8, 10, 13, and 14. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4.1 Exceptions—Where there is no direct SI equivalent such as screw threads, National Pipe Threads/diameters, tubing size, or single source supply equipment specifications. 1.5 This test method is arranged as follows:
