1.1 本试验方法适用于水、地下水和饮用水中溴离子的测量。 1.2 含有0.5 mg/L至1000 mg/L溴化物的样品可通过本试验方法进行分析。可通过稀释适当的小份来扩大浓度范围。 1.3 精度和偏差声明是在自然水和地下水上确定的。分析员有责任确保该测试方法对未测试矩阵的有效性。 1.4 停止了碘和溴的一种滴定法和两种比色法测试方法。 提到 附录X1 以获取历史信息。 1.5 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 通过分析水、废水和微咸水中的溴化物，可以评估水的来源、其作为溴化物来源的潜力及其污染状况。

1.1 This test method is applicable to the measurement of bromide ion in water, ground water, and drinking water. 1.2 Samples containing 0.5 mg/L to 1000 mg/L of bromide may be analyzed by this test method. The concentration range may be extended by the dilution of an appropriate aliquot. 1.3 The precision and bias statements were determined on natural and ground waters. It is the responsibility of the analyst to assure the validity of this test method for untested matrices. 1.4 A titrimetric and two colorimetric test methods for iodide and bromide were discontinued. Refer to Appendix X1 for historical information. 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. 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. ====== Significance And Use ====== 5.1 By analysis for bromide in water, wastewater, and brackish waters, it is possible to evaluate the origin of the water, its potential as a source of bromide, and its condition with regard to pollution.
