Scope

1.1 This test method covers a four-stroke cycle diesel engine test procedure for evaluating engine oils for certain high-temperature performance characteristics, particularly ring sticking, ring and cylinder wear, and accumulation of piston deposits. Such oils include both single viscosity SAE grade and multiviscosity SAE grade oils used in diesel engines. It is commonly known as the 1M-PC test (PC for Pre-Chamber) and is used in several API oil categories, notably the CF and CF-2 and the military category described in MIL-PRF-2104 (see Note 1). NOTE 1—Companion test methods used to evaluate other engine oil performance characteristics for API oil categories CF and CF-2 are discussed in SAE J304. The companion tests used by the military can be found in MIL-PRF-2104. 1.2 The values stated in SI units are to be regarded as standard. 1.2.1 Exception—The values in parentheses are provided for information only. 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. 1.4 This test method is arranged as follows: TABLE OF CONTENTS Scope 1 Reference Documents 2 Terminology 3 Summary of Test Method 4 Significance and Use 5 Apparatus 6 Test Engine 6.1 Engine Accessories 6.2 – 6.14 Engine Oil System 6.15 Cooling System 6.16 Fuel System 6.17 Intake Air System 6.18 Exhaust System 6.19 Blowby Meter 6.20 Thermocouples 6.21 Parts 6.22 Instrumentation 6.23 Crankcase Paint 6.24 Reagents and Materials 7 Fuel 7.1 Test Oil 7.2 Engine Coolant 7.3 Cleaning Materials 7.4 Safety 8 1 This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants and is the direct responsibility of Subcommittee D02.B0.02 on Heavy Duty Engine Oils.
