scope:

This International Standard specifies the procedure for screening soils and soil-like materials for selected elements when handheld or portable energy dispersive XRF spectrometers are used. This procedure is assumed to be applied on-site to obtain analytical data that assists the decision making processes in assessing soil quality.This International Standard does not explicitly specify elements for which it is applicable since the applicability depends on the performance of the apparatus and the objective of the screening. The elements which can be determined are both limited by the performance of instruments used and the requirements of the investigation (e. g. limit values).
