1.1 This test method covers the determination of the purity of cyclohexane by gas chromatography.
1.2 This test method has been found applicable to the measurement of impurities such as those found in , which are impurities that may be found in cyclohexane. The impurities can be analyzed over a range of 1 to 400 mg/kg by this method, but may be applicable to a wider range.
1.3 The limit of detection is 1 mg/kg.
1.4 In determining the conformance of the test results using this test method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice .
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazards statements, see Section .
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
