Thermal extraction - A useful supplement to the emission test chamber

In general the emissions from building materials are tested by emission test chamber experiments. These experiments are carried out over a period e. g. of 28 days. This time consuming test is not suitable for quality control during production. Therefore several methods of thermal extraction have been tested and improved. The aim of this work was to develop a method for the rapid emission testing of building products and other materials. To set up a method for short time testing of flooring materials two different thermal extractors were used. The results of the emission test chamber method and different thermal extraction methods are compared exemplary for one flooring. A thermal extraction method for flooring materials with a good correlation to the test chamber method is presented.
