5.1 Background—Prior to this test method, the ability of an engine lubricant to resist aeration was measured by the engine oil aeration test (EOAT) described in Test Method D6894. The continued availability of engine parts coupled with field service aeration problems led to concerns about the relevance of this test method to newer oil and engine technologies. These concerns prompted the development of this new engine oil aeration test method, based on the Caterpillar C13 engine and termed COAT. This test method aims to provide a more reliable measurement of the ability of a lubricant to resist aeration during engine operation in field service. The engine used is of current technology and the aeration measurement is operator independent.5.2 Test Method—This test method evaluates aeration performance under high-engine-speed, zero-load operation in a turbocharged, heavy-duty, four-stroke diesel engine.5.3 Use: 5.3.1 The tendency of engine oils to aerate in direct-injection, turbocharged diesel engines is influenced by a variety of factors, including engine oil formulation, oil temperature, sump design and capacity, residence time of the oil in the sump, and the design of the pressurized oil systems. In some engine oil-activated systems, the residence time of the oil in the sump is insufficient to allow dissipation of aeration from the oil. As a consequence, aerated oil can be circulated to hydraulically activated components, adversely affecting the engine timing characteristics and engine operation.5.3.2 The results from this test method may be compared against specification requirements such as Specification D4485 to ascertain acceptance.5.3.3 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 unique operating conditions, needs to be considered when comparing the test results against specification requirements.1.1 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 D4485.1.2 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 Exception—Where there is no direct SI equivalent, for example, screw threads, national pipe threads/diameters, and tubing size.1.3 This test method is arranged as follows:  Section 1Referenced Documents 2Terminology 3Summary of Test Method 4 5Apparatus 6Engine Liquids and Cleaning Solvent 7Preparation of Apparatus 8Engine Stand Calibration and Non-Reference Oil Tests 9Procedure 10Calculation, Test Validity and Test Results 11Report 12Precision and Bias 13Keywords 14ASTM Test Monitoring Center Organization Annex A1Safety Precautions Annex A2Engine and Engine Build Parts Kit Annex A3Oil Temperature Control System Annex A4Engine Modifications and Instrumentation Annex A5Flow Density Meter Calibration or Verification Procedure Annex A6Aeration Measurement System Annex A7Specified Units and Formats Annex A8ASTM TMC: Calibration Procedures Annex A9ASTM TMC: Maintenance Activities Annex A10ASTM TMC: Related Information Annex A11Engine Break-in and Silicon Passivation Procedure Annex A12Schedule for Taking Oil Samples and Carrying out Analyses Annex A13Determination of Operational Validity Annex A14Typical System Configuration Appendix X11.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 This test method is intended for use in cases where an experimental determination of heat of combustion is not available and cannot be made conveniently, and where an estimate is considered satisfactory. It is not intended as a substitute for experimental measurement of heat of combustion.1.1 This test method covers the estimation of the gross and net heat of combustion in SI units, megajoules per kilogram, of hydrocarbon fuels and blendstocks from the fuel density and sulfur, water, and ash contents.1.1.1 This test method is not applicable to fuels containing non-hydrocarbons such as alcohols (for example, ethanol, methanol), ethers (for example, MTBE), or esters (for example, biodiesel).NOTE 1: The equation for estimation of net and gross heat of combustion used in this method was originally published as NBS Miscellaneous Publication No. 97.1.2 This test method is especially useful for estimating, using a minimum number of tests, the heat of combustion of burner and diesel fuels (which do not contain non-hydrocarbon components) for which it is not usually critical to obtain very precise heat determinations.NOTE 2: More accurate estimation methods are available for aviation fuels (Test Methods D1405, D4529,and D3338). However, those estimation methods require additional tests to those required in this test method.1.3 This test method is purely empirical (Note 1). It was derived using liquid hydrocarbon fuels produced by normal refining processes from conventional crude oil that conform to the requirements of specifications for petroleum fuels as described in Note 3. This test method is valid for those fuels in the density range from 750 kg/m3 to 1000 kg/m3 and those that do not contain an unusually high aromatic content. High aromatic content fuels will not normally meet some fuel specification criteria.NOTE 3: The estimation of the heat of combustion of a hydrocarbon fuel from its density and sulfur, water, and ash content is justifiable only when the fuel belongs to well-defined classes for which a relationship between these quantities have been derived from accurate experimental measurements on representative samples of these classes. Even in these classes, the possibility that the estimate can be in error for individual fuels should be recognized. This test method has been tested for a limited number of fuels from oil sand bitumen and shale oil origin and has been found to be valid. The classes of fuels used to establish the correlation presented in this test method are represented by the following applications:Fuel (not applicable to any fuels containing non-hydrocarbon components) SpecificationFuel Oils  Grades No. 1, 2, 4 (light), 4, 5 (light), 5 (heavy), and 6 D396Diesel  Grades No. 1-D, 2-D, and 4-D D975Aviation Turbine  Jet A and Jet A-1 D1655Jet B D6615Gas Turbine  Grades No. 0-GT, 1-GT, 2-GT, 3-GT, and 4-GT D2880Kerosene  Grades No. 1-K and 2-K D36991.4 This test method is not applicable to pure hydrocarbon compounds. It is not intended as a substitute for highly accurate experimental measurements of heat of combustion (Note 4).NOTE 4: The procedures for the experimental determination of the gross and net heats of combustion are described in Test Methods D240 and D4809.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 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.

5.1 The determination of group type composition of diesel fuel is useful for evaluating quality and expected performance. Aromatics and polyaromatics, in particular, are related to combustion characteristics, cetane number, energy content, lubricity, water solubility and exhaust emissions.5.1.1 Aromatic hydrocarbon type analysis may be useful for evaluating refinery processes.5.1.2 The ability to determine aromatics content in the presence of FAME may be useful to users of diesel fuel.1.1 This test method covers a standard procedure for the determination of group type totals of aromatic, polyaromatic, and FAME content in diesel fuel using gas chromatography and vacuum ultraviolet absorption spectroscopy detection (GC-VUV).1.1.1 Polyaromatic totals are the result of the summation of diaromatic and tri-plus aromatic group types. Aromatics are the summation of monoaromatic and polyaromatic group types. FAME content is the result of summation of individual fatty acid methyl esters.1.1.2 This test method is applicable for renewable diesel fuels from hydrotreated vegetable oil (HVO) or animal fat, gas to liquid (GTL) diesel, light cycle oil, wide boiling range aromatic solvents and biodiesel blends.1.2 Concentrations of group type totals are determined by percent mass or percent volume. The applicable working ranges are as follows:Total Aromatics %Volume 0.088 to 77.000Total Aromatics %Mass 0.104 to 79.451MonoAromatics %Mass 0.076 to 67.848Diaromatics %Mass 0.027 to 34.812Tri-plus aromatics %Mass 0.45 to 6.77PAH %Mass 0.028 to 41.586FAME %Volume 1.08 to 21.671.3 Diesel fuel containing biodiesel, (FAME, that is, fatty acid methyl esters including soy methyl esters, rapeseed methylesters, tallow methylesters and canola methylesters) can be analyzed by this test method. The FAME component completely elutes from the analytical column independent of feedstock.1.4 Individual hydrocarbon components are not reported by this test method; however, any individual component determinations are included in the appropriate summation of the totals of aromatic, polyaromatic, monoaromatic, diaromatic, tri-plus aromatic, or FAME groups.1.4.1 Individual components are typically not baseline-separated by the procedure described in this test method. The coelutions are resolved at the detector using VUV absorbance spectra and deconvolution algorithms.1.5 This test method may apply to other hydrocarbon streams boiling between heptane (98 °C) and triacontane (450 °C), but has not been extensively tested for such applications.1.6 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 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.1.8 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.

4.1 In diesel fuel, the presence of alkyl nitrates such as amyl nitrate, hexyl nitrate, or octyl nitrate causes a higher residue value than observed in untreated fuel, which can lead to erroneous conclusions as to the coke forming propensity of the fuel. The presence of such alkyl nitrate in the fuel can be determined using this test method. This test method can be used to determine the amount of alkyl nitrate that has been added to diesel fuel to improve Cetane Number. The test method is applicable as a basis for judging compliance with specifications covering any alkyl nitrate.1.1 This test method covers a procedure for the determination of 0.03 % to 0.30 % by volume of alkyl nitrate in diesel fuels.1.2 This test method can be used for the determination of any alkyl nitrate in diesel fuel provided that standards used for calibration contain the same alkyl nitrate ester as the test specimens to be analyzed.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 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. For specific hazard statements, see Section 7.1.5 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.
