Over deze norm
1.1 This test method covers the quantitative determination of phenol and certain homologues of phenol in tar acid and cresylic acid mixtures using capillary gas chromatography. It is a normalization test method that determines homolog distribution but is not an absolute assay since it does not account for water or other compounds not detected by a flame ionization detector.
1.2 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice .
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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 specific hazard statements, see Section .
