HANDBOOK - Environmental Assessment of Construction Products - An introduction to test methods and other procedures related to CE-marking (NT TR 618)

NT TR 618

  • This handbook presents an overview of the technical, regulatory and administrative framework within which CE marking of construction products takes place and offers guidance on the selection of test methods for assessment of release of regulated dangerous substances from construction products to soil, surface water and groundwater. The handbook includes information on how test results can be used, e.g. by regulators when comparing regulatory limit values with test results.

Leaching of organic contaminants from construction debris - Development of a diffusion test procedure (NT TR 577)

NT TR 577

  • A test procedure has been designed to determine diffusion of organic contaminants from monolithic materials. The method is based on the use of a scavenger with a high sorption capacity which allows a near zero aqueous concentration and there by achieves a maximum diffusion gradient from the test object.

CEN EN 12457 leaching test - Comparison of test results obtained by part 1 and 2 with test results obtained by part 3 (NT TR 539)

NT TR 539

  • The report compares leaching results obtained by two one-step batch leaching tests (en 12457 part 1 and 2) with leaching results obtained by a two-steps batch-leaching test (EN 12457 part 3). The effect of the used contact time and the effect of using different number of leaching steps were evaluated.
