SUPERSEDED (see Active link, below)
ASTM D6142
1. Scope
1.1 This test method covers the determination of known impurities in phenol by gas chromatography (GC). It is generally meant for the analysis of phenol of 99.9% or greater purity.
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 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. Precision data is based on impurity concentrations of 15 to 70 mg/kg. Users of this test method believe it is linear over a wider range.
1.3 This Test Method 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 9.
