Standard Test Method for Evaluation of Automotive Engine Oils in the Sequence IIIH, Spark-Ignition Engine

SIGNIFICANCE AND USE
5.1 This test method was developed to evaluate automotive engine oils for protection against oil thickening and piston deposits during moderately high-speed, hightemperature service.  
5.1.1 The increase in kinematic viscosity of the oil indicates the tendency of an oil to thicken because of oxidation. In automotive service, such thickening can cause oil pump starvation and resultant catastrophic engine failures.  
5.1.2 The deposit ratings for an oil indicate the tendency for the formation of deposits throughout the engine, including those that can cause sticking of the piston rings in their grooves. In automotive service, such ring sticking can cause a loss of compression pressures in the engine.  
5.2 The test method was developed to correlate with oils of known good and poor protection against oil thickening and piston deposits. Specially formulated oils that produce less than desirable results with unleaded fuels were also used during the development of this test.  
5.3 The Sequence IIIH engine oil test has been recommended as a replacement for the Sequence IIIG test and is expected to be used in specifications and classifications of engine lubricating oils, such as the following:  
5.3.1 Specification D4485.  
5.3.2 Military Specification MIL-PRF-2104.  
5.3.3 SAE Classification J183.
SCOPE
1.1 This test method covers an engine test procedure for evaluating automotive engine oils for certain high-temperature performance characteristics, including oil thickening (as measured by kinematic viscosity increase), piston deposits, ring sticking, oil consumption, and phosphorus retention. Such oils include both single-viscosity and multiviscosity grade oils that are used in both spark-ignition, gasoline-fueled engines, as well as in diesel engines.  
1.1.1 Additionally, with nonmandatory supplemental requirements, a Sequence IIIHA Test (Mini Rotary Viscometer and Cold Cranking Simulator measurements), or a Sequence IIIHB Test (phosphorus retention measurement) can be conducted. These supplemental test procedures are contained in Appendix X1 and Appendix X2, respectively.
Note 1: Companion test methods used to evaluate engine oil performance for specification requirements are discussed in 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:  
1.2.1.1 Where there is no direct SI equivalent such as screw threads, national pipe threads/diameters, tubing sizes, and valve sizes and springs.
1.2.1.2 The ring end gaps in Table A8.7, the dimensions for the blowby ventilation support bracket in Fig. A3.2, and the torque wrenches in Table A8.1 are in 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific warning statements are provided in 6.11.6, 7.1, 7.2.1, and 7.3.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Committee of the Lubricant Review Institute (SAE International) require that a laboratory use the
TMC services in seeking qualification of oils against their specifications.
The advantage of using the TMC services to calibrate test stands is that the test laboratory (and
hence the test purchaser) has an assurance that the test stand was operating at the proper level of test
severity. It should also be borne in mind that results obtained in a non-calibrated test stand may not
be the same as those obtained in a test stand participating in the ASTM TMC services process.
ASTM International policy is to encourage the development of test procedures based on generic
equipment. It is recognized that there are occasions where critical/sole-source equipment has been
approved by the technical committee (surveillance panel/task force) and is required by the test
procedure. The technical committee that oversees the test procedure is encouraged to clearly identify
if the part is considered critical in the test procedure. If a part is deemed to be critical, ASTM

An alternative supplier can start the process by initiating contact with the technical committee
(current chairs shown onASTM TMC website). The supplier should advise on the details of the part
that is intended to be supplied. The technical committee will review the request and determine
feasibility of an alternative supplier for the requested replacement critical part. In the event that a
replacement critical part has been identified and proven equivalent the sole-source supplier footnote
