Metadata for publikationen
The Joint Research Centre (JRC) organised an interlaboratory comparison to evaluate the precision of methods developed by the European Committee for Standardization (CEN) to assess the release of inorganic hazardous substances from construction products. The CEN Technical Committee 351 "Construction Products - Assessment of release of dangerous substances" developed, among others, horizontal leaching and percolation procedures to assess the release from construction products into soil, ground water and surface water and horizontal standardised procedures for content and eluate analysis. These procedures are valid for organic and inorganic substances and take into account the intended conditions of use of the product. The interlaboratory comparison was part of the validation of the methods aiming to convert them in European standards. This work was done in support of the Regulation 305/2011/EU (Construction Products Regulation). The objective of this study was to evaluate for inorganic substances the precision (repeatability and reproducibility) of the methods developed by CEN Technical Committee 351 on dynamic surface leaching and up-flow percolation procedures from construction products, analysis of leachates/eluates and content analysis. This was done by comparing the results obtained by different expert laboratories when they analysed samples of the same materials using the CEN methods under validation.
