Over deze norm
1.1 This practice covers a procedure for leaching of solid waste to obtain an aqueous solution to be used to determine the constituents leached under the specified testing conditions.
1.1.1 This practice includes a procedure for the shake leaching of metal mining ore, waste rock, or metallurgical processing waste containing at least 80 % dry solids (≤20 % moisture) in order to generate a solution to be used to determine the inorganic constituents leached under the specified testing conditions and for regulatory jurisdictions requiring a water leach practice.
1.2 This practice provides for the shaking of a known mass of waste with water of specified composition and the separation of the aqueous phase for analysis.
1.2.1 This practice is intended to describe the procedure for performing single-batch extractions only. It does not describe all types of sampling, sample preservation, and analytical requirements that may be associated with its application.
1.3 The values stated in SI units are to be regarded as standard. Values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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.
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.
