적용범위 | 1.1?This test method covers the determination of inorganic chloride (chloride ion) in monoethylene glycol (MEG), diethylene glycol (DEG) and triethylene glycol (TEG). 1.1.1?This test method is applicable to samples with chloride concentrations up to 1.0?mg/kg by ion chromatography (IC). The limit of detection (LOD) is 0.004 mg/kg and the limit of quantitation is 0.012 mg/kg Cl in MEG using configuration A. The limit of detection (LOD) is 0.002 mg/kg and the limit of quantitation is 0.006 mg/kg Cl in MEG using configuration B. 1.2?Ethylene glycol can be analyzed directly by this test method without any sample preparation or diluted with high quality deionized water if an autosampler is used and dilution is necessary (that is, 50:50 or other suitable ratio). 1.3?The following applies for the purposes of 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 E29. 1.4?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4.1?The exception is the additional information of (psi) in 9.3.3, 11.1.1, and 11.2.1. 1.5?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 to determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9. 1.6?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. |
