Olfactometers According to EN 13725

Abstract

In 1995 the technical committee TC264 air quality of the European Committee for Standardization convened the working group 2, which developed an odor testing standard. It was released in 2003 as EN 13725 air quality – measurement of odor concentration using dynamic olfactometry. As the methodology of dynamic olfactometry according this European Standard is approved among others in Australia as AS 4323.1 and in Chile as NCh 3190, the EN 13725 today is the most applied standard worldwide. Other used methods for determination of odor thresholds are ASTM 679 as well as Japanese and Chinese standards. Compared with the EN 13725 these standards are working on a lower detail level concerning technical requirements and execution description. In 2012 the TC264 took a resolution to review the standard. A revised draft standard is expected to become available in 2017. The revised standard will contain comprehensive guidance on reference material, measurement uncertainty, health and safety issues, materials for olfactometry, sample storage and the sampling of different odor sources. Once the endpoint of the revision has been reached a release of an ISO standard based on EN 13725 is envisaged.
