This test method covers the determination of benzene, toluene, ethylbenzene, the xylenes, C9 and heavier aromatics, and total aromatics in finished motor gasoline by gas chromatography. The aromatic hydrocarbons are separated without interferences from other hydrocarbons in finished gasoline....
This test method covers the determination of apparent specific gravity (Sections 5 to 9) and true specific gravity (Sections 10 to 14) of lump coke larger than 25 mm [1 in.] size and calculating porosity (Section 15) from the specific gravity data. Units-The values stated in either SI units or...
This practice applies to the blending of automotive spark-ignition engine fuels with ethanol concentrations greater than those suitable for conventional-fuel vehicles and less than the minimum ethanol content specification limits of Specification D5798. These mid-level ethanol fuel blends are for...
These test methods cover the determination of lead and manganese gasoline additives content by X-Ray Fluorescence Spectroscopy (XRF). These test methods cover the determination of the total lead content of a gasoline within the following concentration ranges: 0.010 g Pb ⁄US gal to 5.0 g Pb ⁄US gal...
This specification (see Note 1) covers grades of fuel oil intended for use in various types of fuel-oil-burning equipment under various climatic and operating conditions. These grades are described as follows: Grades No. 1 S5000, No. 1 S500, No. 1 S15, No. 2 S5000, No. 2 S500, and No. 2 S15 are...
This specification covers additives for aviation fuels (for example, Specifications D910, D7547, and D1655) used to inhibit ice formation in aircraft fuel systems. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard....
Test Method A covers the determination of carbon in the range of 54.9 % to 84.7 %, hydrogen in the range of 3.26 % to 5.08 %, and nitrogen in the range of 0.57 % to 1.76 % in analysis samples (8.1) of coal and of carbon in analysis samples of coke in the range of 86.6 % to 97.9 %....
This test method covers a protocol for capturing, extracting and quantifying the cellular adenosine triphosphate (cellular-ATP) content associated with microorganisms found in fuels and fuel-associated water. The ATP is measured using a bioluminescence enzyme assay, whereby light is generated in...
This specification covers butanol intended to be blended with gasoline at 1 % to 12.5 % by volume for use as an automotive spark-ignition engine fuel. Butanol contains 22 % by mass oxygen. The mass percent of oxygen of a butanol blend with gasoline depends on the volume percent of butanol blended,...
This test method provides a protocol for capturing, concentrating, and testing the adenosine triphosphate (ATP) present in a fuel system sub-sample (that is, test specimen) associated with: Microorganisms and hydrophilic particles found in liquid fuels as described in Table X6.1, or Microorganisms...
This test method describes a procedure that can be used in the field or in a laboratory to detect antigens indicative of microbial contamination in liquid fuels, including those blended with synthesized hydrocarbons or biofuels, with kinematic viscosities (at 40 °C) of ≤24 mm2s-1 (for example,...
This specification covers nominally anhydrous denatured fuel ethanol intended to be blended with unleaded or leaded gasolines at 1 % to 15 % by volume for use as automotive spark-ignition engine fuel covered by Specification D4814 as well as other fuel applications or specifications involving...
This specification covers the requirements of a high octane number test fuel suitable for spark-ignition engines to be utilized in ground vehicles that will require 100 research octane number (RON) minimum rated fuel. The fuels described by this specification are intended for developing...
This specification covers the establishment of requirements of liquid automotive fuels for ground vehicles equipped with spark-ignition engines.
