Standard Test Method for Evaluation of Heavy-Duty Engine Oils under High Output Conditions—;Caterpillar C13 Test Procedure — 36 стр.
Значение и использование

5.1 This test method assesses the performance of an engine oil with respect to control of piston deposits and maintenance of oil consumption under heavy-duty operating conditions selected to accelerate deposit formation in a turbocharged, intercooled four-stroke-cycle diesel engine equipped with a combustion system that minimizes federally controlled exhaust gas emissions.

5.2 The results from this test method may be compared against specification requirements to ascertain acceptance.

5.3 The design of the test engine used in this test method is representative of many, but not all, diesel engines. This factor, along with the accelerated operating conditions, needs to be considered when comparing test results against specification requirements.

Область применения

1.1 The test method covers a heavy-duty engine test procedure under high output conditions to evaluate engine oil performance with regard to piston deposit formation, piston ring sticking and oil consumption control in a combustion environment designed to minimize exhaust emissions. This test method is commonly referred to as the Caterpillar C13 Heavy-Duty Engine Oil Test.3

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 are no SI equivalent such as screw threads, National Pipe Treads (NPT), and tubing sizes.

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. See Annex A1 for general safety precautions.
