1.1 试验方法1、2和3- 这些试验方法包括测定卤化有机溶剂及其混合物中的水可萃取卤化物离子。由于氟化银的溶解性，未测量氟离子。 1.2 试验方法4- 本试验方法涵盖卤化有机溶剂及其混合物中氯离子的测定。 1.3 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。 1.4 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。 第节给出了具体的预防说明 6. . 1.5 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====== 3.1 这些测试方法用于制定制造和采购规范。这些试验方法将提供一种确定所用溶剂状况的方法。水溶性氯化物含量高可能表明溶剂分解开始。

1.1 Test Methods 1, 2, and 3— These test methods cover the determination of water-extractable halide ion in halogenated organic solvents and their admixtures. Fluoride ion is not measured due to the solubility of silver fluoride. 1.2 Test Method 4— This test method covers the determination of chloride ion in halogenated organic solvents and their admixtures. 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 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 precautionary statements are given in Section 6 . 1.5 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 ====== 3.1 These test methods are used to establish manufacturing and purchasing specifications. These test methods will provide a means of determining the condition of the solvent in use. A high water soluble chloride level may indicate the start of solvent decomposition.
