Recently, an internationally harmonized method for the characterizatio
n of emissions of organic compounds from building materials in test ch
ambers has been developed and tested at the EMPA. Selected results fro
m two projects indicate clearly, that the emissions not only depend on
the building material but are also strongly influenced by the mode of
application. It is shown that some emissions caused by wall paints ar
e influenced by the structure and material of the wall on which they a
re applied. Emissions from glues depend very strongly on structure and
thickness of the glued materials.
