1.1 本试验方法使用高效液相色谱法（HPLC）测定10 μg/g（ppm）至1400μ。 1.2 查看当前的安全数据表（SDS），了解有关毒性、急救程序和安全预防措施的详细信息。 1.3 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。 1.4 以下适用于确定使用该测试方法的测试结果是否符合适用规范的目的，应根据实践中的舍入方法对结果进行舍入 E29 . 1.5 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。 具体危害说明见第节 8. . 1.6 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 本试验方法用于测定液氯中氯化溴的含量。溴是氯生产中使用的所有盐源中的常见污染物。盐中的溴含量在液氯产品中转化为氯化溴。该试验方法足够灵敏，可以测量正常生产氯中观察到的氯化溴含量。

1.1 This test method uses high performance liquid chromatography (HPLC) to determine bromine chloride levels in liquid chlorine at the 10 μg/g (ppm) to 1400 μg/g (ppm) range. 1.2 Review the current safety data sheet (SDS) for detailed information concerning toxicity, first aid procedures, and safety precautions. 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 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 . 1.5 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 determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 8 . 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. ====== Significance And Use ====== 4.1 This test method was developed for the determination of bromine chloride in liquid chlorine. Bromide is a common contaminant in all salt sources that are used in the production of chlorine. This bromide content of the salt is converted into bromine chloride in the liquid chlorine product. This test method is sensitive enough to measure the levels of bromine chloride observed in normal production chlorine.
