ISO 16387:2014 specifies one of the methods for evaluating the habitat function of soils and determining effects of soil contaminants and substances on the reproduction of Enchytraeus sp. by dermal and alimentary uptake in a chronic test. It is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, agricultural or other sites under concern and waste materials. ISO 16387:2014 provides information on how to use this method for testing substances under temperate conditions.
