CONTAINED IN VOL. 05.04, 2016 Defines the determination of individual hydrocarbon components of spark-ignition engine fuels with boiling ranges up to 225 degrees C.

1.1 This test method covers the determination of individual hydrocarbon components of spark-ignition engine fuels with boiling ranges up to 225°C. Other light liquid hydrocarbon mixtures typically encountered in petroleum refining operations, such as, blending stocks (naphthas, reformates, alkylates, and so forth) may also be analyzed; however, statistical data was obtained only with blended spark-ignition engine fuels. The tables in enumerate the components reported. Component concentrations are determined in the range from 0.10 to 15 mass %. The procedure may be applicable to higher and lower concentrations for the individual components; however, the user must verify the accuracy if the procedures are used for components with concentrations outside the specified ranges.

1.2 This test method is applicable also to spark-ignition engine fuel blends containing oxygenated components. However, in this case, the oxygenate content must be determined by Test Methods D 5599 or D 4815.

1.3 Benzene co-elutes with 1-methylcyclopentene. Benzene content must be determined by Test Method D 3606 or D 5580.

1.4 Toluene co-elutes with 2,3,3-trimethylpentane. Toluene content must be determined by Test Method D 3606 or D 5580.

1.5 Although a majority of the individual hydrocarbons present are determined, some co-elution of compounds is encountered. If this procedure is utilized to estimate bulk hydrocarbon group-type composition (PONA) the user of such data should be cautioned that error may be encountered due to co-elution and a lack of identification of all components present. Samples containing significant amounts of naphthenic (for example, virgin naphthas) constituents above n-octane may reflect significant errors in PONA type groupings. Based on the interlaboratory cooperative study, this procedure is applicable to samples having concentrations of olefins less than 20 mass %. However, significant interfering coelution with the olefins above C7 is possible, particularly if blending components or their higher boiling cuts such as those derived from fluid catalytic cracking (FCC) are analyzed, and the total olefin content may not be accurate. Many of the olefins in spark ignition fuels are at a concentration below 0.10 %; they are not reported by this test method and may bias the total olefin results low.

1.5.1 Total olefins in the samples may be obtained or confirmed, or both, by Test Method D 1319 (volume %) or other test methods, such as those based on multidimensional PONA type of instruments.

1.6 If water is or is suspected of being present, its concentration may be determined, if desired, by the use of Test Method D 1744. Other compounds containing sulfur, nitrogen, and so forth, may also be present, and may co-elute with the hydrocarbons. If determination of these specific compounds is required, it is recommended that test methods for these specific materials be used, such as Test Method D 5623 for sulfur compounds.

1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.

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.
