All construction materials that are used in or on Dutch soils must meet the requirements of the Dutch Soil Quality Decree. This means that requirements have been set for the composition or the leaching behaviour of these materials.
TCKI has been AP04 accredited to conduct this examination for both standard and abbreviated tests on monolithic construction materials in general. TCKI is a laboratory that has been appointed for this by the Dutch government.
For measuring the leaching behaviour, element concentrations of metals and anions in different leaching steps are used to calculate emissions from a product. The result can be compared with the excisting limit values.
