Title
Standard Test Method for Analysis of Phenol by Capillary Gas Chromatograpy
ASTM International
Publication Date:
Feb 10, 2003
Scope:
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.
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.
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 9.
