ICS Code (Lubricants, industrial oils and related products): 75.100
scope:

This test method evaluates an engine oil's resistance to aeration in automotive diesel engine service. It is commonly referred to as the Caterpillar-C13 Engine-Oil Aeration Test (COAT). The test is conducted under high-engine-speed (1800 r⁄min), zero-load conditions using a specified Caterpillar 320 kW, direct-injection, turbocharged, after-cooled, six-cylinder diesel engine designed for heavy-duty, on-highway truck use. This test method was developed as a replacement for Test Method D6894.

NOTE 1-Companion test methods used to evaluate engine oil performance for specification requirements are discussed in the latest revision of Specification D4485.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Exception-Where there is no direct SI equivalent, for example, screw threads, national pipe threads/diameters, and tubing size.

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. See Annex A2 for general safety precautions.

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.
