scope:

This International Standard describes a method for determining the inhibition of the growth and reproductive capability of higher plants by soils under controlled conditions. Two species are recommended: a rapid cycling variant of turnip rape and oat. The duration of the test should be sufficient to include chronic endpoints that demonstrate the reproductive capability of the test plants. By using natural test soils, e.g. from contaminated sites or remediated soils, and by comparing the development of the test plants in these soils with reference or standard control soils, the test can be used to assess soil quality, especially the function of the soil as an habitat for plants. It is not within the scope of this standard to describe methods for the representative sampling of soils from contaminated sites.
