    Scope - (Show below) - (Hide below)

    1.1This test method is a standard procedure for the determination in percent mass or percent volume of hydrocarbon group types (paraffins, isoparaffins, olefins, naphthenes, aromatics), methanol, ethanol, benzene, toluene, ethylbenzene, xylenes, naphthalene, and methylnaphthalenes in automotive spark-ignition engine fuels using gas chromatography and vacuum ultraviolet detection (GC-VUV).

    1.1.1The concentration ranges for which precision has been determined are as follows:

    Property

    Units

    Applicable Range

    Paraffins

    % Volume

    3.572 to 23.105

    Isoparaffins

    % Volume

    22.697 to 71.993

    Olefins

    % Volume

    0.011 to 44.002

    Naphthenes

    % Volume

    0.606 to 18.416

    Aromatics

    % Volume

    14.743 to 58.124

    Methanol

    % Volume

    0.063 to 3.426

    Ethanol

    % Mass

    0.042 to 15.991

    Benzene

    % Volume

    0.09 to 1.091

    Toluene

    % Volume

    0.698 to 31.377

    Ethylbenzene

    % Volume

    0.5 to 3.175

    Xylenes

    % Volume

    3.037 to 18.955

    Naphthalene

    % Volume

    0.019 to 0.779

    Methylnaphthalenes

    % Volume

    0.21 to 1.484

    1.1.2This test method may be applicable to other concentration ranges, to other properties, or to other hydrocarbon streams, however precision has not been determined.

    1.2Individual hydrocarbon components are typically not baseline-separated by the procedure described in this test method, that is, some components will coelute. The coelutions are resolved at the detector using VUV absorbance spectra and deconvolution algorithms.

    1.3While this test method reports percent mass and percent volume for several specific components that may be present in automotive spark-ignition engine fuel, it does not attempt to speciate all possible components that may occur in automotive spark-ignition engine fuel. In particular, this test method is not intended as a type of detailed hydrocarbon analysis (DHA).

    1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.5This 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 specific hazard statements in subsection 8.4 and Section 9.

    1.6This 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.
