ISO/TC190/Soil Quality has developed a standard to enable measurement of the bioavailability of organic contaminants in soil and soil like materials (ISO/TS16751), To become a full standard a validation is necessary. The validation is based on an intra laboratory validation carried out by the laboratory of Rijkswaterstaat in Lelystad (The Netherlands), and on an international interlaboratory validation study organized by WEPAL, Wageningen. Results are evaluated according ISO 5725. As decided by the responsible ISO-working group, the results support the transfer of ISO/TS 16751 into a full ISO-standard.
