1.1 本规程旨在确定当废物与空气、水、强酸、强碱、油/溶剂混合物、其他废物混合物或固体介质（如地质构造或固化剂）混合时是否发生反应。 1.2 也可以定义废料与上述介质的混溶性。 注1: 以下ASTM标准提供了补充信息:试验方法 D4978 , D4980 , D4982 , D5049 和 D5057 和实践 D4979 , D4981 和 D5058 . 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。 有关具体的危险说明，请参阅第节 8. . 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====== 5.1 这种做法将确定在废物处理或处置场与其他材料接触时可能不稳定的废物。 5.2 本规程将用于确定废料与各种介质（包括其他废物）的相容性。 5.3 这种做法可能不适用于所有废物。这些测试的适当性取决于拟议的废物管理。 5.4 由于某些化学反应的开始很慢，用户可能希望在观察任何反应的混合物之前确定试剂与废物的接触时间。

1.1 This practice is designed to determine whether a waste material reacts when it is mixed with air, water, strong acid, strong base, an oil/solvent mixture, other waste mixtures, or solid media such as a geological formation or solidification agents. 1.2 The miscibility of the waste material with the above media can also be defined. Note 1: The following ASTM standards provide supplemental information: Test Methods D4978 , D4980 , D4982 , D5049 , and D5057 and Practices D4979 , D4981 , and D5058 . 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. For specific hazard statements, see Section 8 . 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 ====== 5.1 This practice will identify waste materials that are potentially unstable when they come in contact with other materials at a waste treatment or disposal site. 5.2 This practice will serve to determine the miscibility of waste materials with various media, including other wastes. 5.3 This practice may not be applicable to all wastes. The appropriateness of these tests depends upon the proposed management of the waste. 5.4 Since the initiation of some chemical reactions are slow to take place, the user may wish to establish reagent-to-waste contact times prior to observing the mixes for any reactions.
