1.1 本试验方法适用于液体芳烃和环己烷中总氯化物（有机和无机）的测定。 1.2 本试验方法适用于氯化物浓度为1的样品 mg/kg至25mg/kg。 1.3 溴化物和碘化物（如果存在）将按氯化物计算。 1.4 通过联苯钠试剂聚合的材料，如苯乙烯，不能通过该测试方法进行分析。 1.5 在使用该方法确定试验结果是否符合适用规范时，应根据实践中的舍入方法对结果进行舍入 E29 . 1.6 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.7 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体的危险说明，请参阅第节 7. . 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 有机和无机氯化合物可能对涉及芳烃的工艺中的设备和反应产生有害影响。 4.2 工艺流和芳烃产品通常规定最高氯化物含量。

1.1 This test method covers the determination of total chloride (organic and inorganic) in liquid aromatic hydrocarbons and cyclohexane. 1.2 The test method is applicable to samples with chloride concentrations of 1 mg/kg to 25 mg/kg. 1.3 Bromides and iodides, if present, will be calculated as chlorides. 1.4 Materials, such as styrene, that are polymerized by sodium biphenyl reagent cannot be analyzed by this test method. 1.5 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 . 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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 a specific hazard statement, see Section 7 . 1.8 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. ====== Significance And Use ====== 4.1 Organic and inorganic chlorine compounds can have a deleterious effect on equipment and reactions in processes involving aromatic hydrocarbons. 4.2 Maximum chloride levels are often specified for process streams and for aromatic hydrocarbon products.
