- Scope
- This document specifies the test principle, information on the test substance, reference substance/reference substance, test method, test procedure, quality assurance and quality control, data and reports of the test method for testing the leaching properties of chemicals in soil columns. This document is suitable for evaluating the transformation in soil and migration (leaching) of chemical substances (including radioactive markers or non-markers, such as 14C) with sufficient accuracy and sensitivity analytical methods to deep soil Potential. This document does not apply to chemical substances that can volatilize from soil and water under test conditions, resulting in no retention in soil or drench solution.
