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 is applicable for benzene purities of 99.80 weight % or higher.
1.3 The lower limit for detection for non-aromatic impurities is 50 mg/kg. The lower limit of detection for individual aromatic hydrocarbon impurities 10 mg/kg. The lower limit of detection for 1,4-dioxane is 5 mg/kg.
1.4 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 E29.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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.
