    Scope - (Show below) - (Hide below)

    1.1These test methods cover the determination of ethylbenzene and total eight-carbon (C8) and heavier aromatics in the concentration range from 0.1 to 30 % in mineral spirits having a distillation range from 149 to 210 °C (300 to 410 °F) as determined by Test Method D86. The procedures permit the identification and calculation of concentrations of aromatic components to 0.1 volume %.

    1.2It is recognized by analytical chemists that a single column gas chromatography analysis of an unknown sample is risky. In such cases, multiple and different analytical techniques must be used for absolutely positive identification, for example, several different gas chromatography columns, gas chromatography/mass spectrometer, or gas chromatography/infrared, etc. In these test methods the material is known and is clearly defined.

    1.3Oxygenated compounds, if present, may interfere and cause erroneous results. Such oxygenated compounds are not normally present in mineral spirits.

    1.4Three test methods are covered as follows:

    1.4.1Test Method A, measurement of ethylbenzene content, C8 plus higher aromatics (except ethylbenzene), and total aromatics by means of a single packed column gas chromatographic analysis.

    1.4.2Test Method B, measurement of ethylbenzene content by means of a rapid packed column gas chromatographic analysis.

    1.4.3Test Method C, measurement of ethylbenzene content, C8 plus higher aromatics (except ethylbenzene) and total aromatics by means of a capillary column gas chromatographic analysis.

    1.5The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

    1.6For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.

    1.7For hazard information and guidance, see the supplier’s Material Safety Data Sheet.

    1.8This 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.

    1.9This 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.
