SUPERSEDED (see Active link, below)
ASTM D4492
1. Scope
1.1 This test method covers the determination of normally occurring trace impurities in, and the purity of, finished benzene by gas chromatography.
1.2 This test method was judged applicable for nonaromatic impurities at levels from 0.001 to 0.200 weight % and for benzene purities of 99.80 weight % or higher.
1.3 This test method is applicable for aromatic impurities from 0.001 to 0.010 weight % in benzene.
1.4 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 E 29.
1.5 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 specific hazard statements, see Section 8.
