Short description
Odour emissions often arise from liquids that contain odorants. In order to assess a liquid concerning its ability to emit odorants, it is necessary to measure the total content of odorants in that liquid. The procedure to attain this goal is to measure the odour emission capacity (OEC). The principle of the OEC measurement according to this standard is to aerate a sample of the liquid under investigation with neutral air. The reactor´s off-gas is filled in sampling bags after fixed time intervals. These samples are analysed via olfactometry according to DIN EN 13725.
