This test method will identify waste materials that are potentially unstable when they come in contact with other materials at a waste treatment or disposal site.

This test method will serve to determine the miscibility of waste materials with various media, including other wastes.

This test method may not be applicable to all wastes. The appropriateness of these tests depends upon the proposed management of the waste.

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 test method 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 D 4978, D 4979, D 4980, D 4981, D 4982, D 5049, D 5057, and D 5058.

1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
