From the results of a study, carried out between 1993-1995 it appearedthat in a number of cases the leaching behavior of granular materials can not be described accurately on the basis of the standard NEN 7343 ('Determination of the leaching of inorganic constituents from granular materials with the column test'). Therefore, a new diffusion test for granular materials is drafted. If applicable, a concept standard for the determination of the emission by diffusion from granular materials will be formulated, as well as a definition of the scope and data analysis of the test results with respect to the use of the method for covered building materials. 17 refs.
