Historical Standard: ASTM D5060-95(2000) Standard Test Method for Determining Impurities in High-Purity Ethylbenzene by Gas Chromatography
SUPERSEDED (see Active link, below)
ASTM D5060
1. Scope
1.1 This test method describes the analysis of normally occurring impurities in, and the purity of, ethylbenzene by gas chromatography. Impurities determined include nonaromatic hydrocarbons, benzene, toluene, xylenes, cumene, and diethylbenzene isomers.
1.2 This test method is applicable for impurities at concentrations from 0.001 to 1.000% and for ethylbenzene purities of 99% or higher. At this level, -xylene may not be detected.
1.3 The following applies to all specified limits in this standard: for purposes of determining conformance with this standard, an observed value or a calculated value 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.
1.4 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 7.
