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.

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.
