| Note in Official Journal: | |
| Subject of the standard: | This document specifies a test to obtain information on the short- and long-term leaching behaviour and characteristic properties of materials. The document has been developed to measure the pH-dependent release of inorganic and organic substances from soil and soil-like material as well as to produce eluates for subsequent ecotoxicological testing. For ecotoxicological testing, see ISO 15799 and ISO 17616. The equilibrium condition, as defined in this document, is established by the addition of predetermined amounts of acid or base to reach desired final pH values. |
