    Withdrawn Rationale:

    This test method covers the determination of known hydrocarbon impurities in, and the purity of p-xylene by gas chromatography (GC). It is generally meant for the analysis of p-xylene of 99 % or greater purity. Impurity concentrations that can be measured range from 0.001 to 1.000 weight %.

    Formerly under the jurisdiction of Committee D16 on Aromatic Hydrocarbons and Related Chemicals, this test method was withdrawn in June 2009 and replaced by Test Method D 5917 for Trace Impurities in Monoclyclic Aromatic Hydrocarbons by Gas Chromatography and External Calibration and Test Method D 7504 for Trace Trace Impurities in Monocyclic Aromatic Hydrocarbons by Gas Chromatography and Effective Carbon Number.

    1. Scope

    1.1 This test method covers the determination of known hydrocarbon impurities in, and the purity of p-xylene by gas chromatography (GC). It is generally meant for the analysis of p-xylene of 99 % or greater purity. Impurity concentrations that can be measured range from 0.001 to 1.000 weight %.

    1.2 The following applies to all specified limits in this test method: for purposes of determining conformance with this test method, an observed value or a calculated value shall be rounded off 'to the nearest unit' in the right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29.

    1.3 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. For a specific hazard statement, see Section 9.
