ASTM-D5284 › Standard Test Method for Sequential Batch Extraction of Waste with Acidic Extraction Fluid
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method provides a procedure for the sequential leaching of a waste containing at least 5% dry solids in order to generate solutions to be used to determine the constituents leached under the specified testing conditions.
1.2 This test method calls for the shaking of a known weight of waste with acidic extraction fluid of a specified composition as well as the separation of the liquid phase for analysis. The pH of the extraction fluid is to reflect the pH of acidic precipitation in the geographic region in which the waste being tested is to be disposed. The procedure is conducted ten times in sequence on the same sample of waste, and it generates ten solutions.
1.3 This test method is intended to describe the procedure for performing sequential batch extractions only. It does not describe all types of sampling and analytical requirements that may be associated with its application.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 This standard does not purport to address all of the safety problems, 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.
