This International Standard which has been taken over by CEN/TC 345 into the European body of standards provides a guideline for the selection and application of on-site methods (screening) for assessing soil quality. It provides guidance on the selection of an appropriate screening method for the determination of a specific parameter and the conditions under which it can be obtained. This International Standard does not recommend any particular screening method, but confirms the principles of their selection and application. The use of screening methods, particularly if carried out on-site, can offer an immediate decision-making opportunity which enables staff to direct their efforts more effectively to those areas where a more thorough investigation might need to be undertaken. The guidance in this International Standard describes the application of screening methods, and how they might be used for assessing soil quality. Notwithstanding some of the issues raised, screening methods can generate robust and reliable results which can be used with confidence.
