In June this year, Mr Antonsson and his collaborators dropped a bombshell on the waterline of the standard governing dynamic olfactometry with the publication of their scientific paper published in Atmospheric Environment. The EN 13725 standard assumes that assessors' sensitivity to 1-butanol is transferable to other odours. However, the study reveals that this sensitivity transfer is not valid for other odorous substances, calling into question the uniform application of the standard.
You may imagine how much debate this research has generated. We have participated in threads and threads of conversations with several world experts in odour management, commenting on the results of the following paper. The paper analyses the reproducibility of odour testing using the EN 13725 standard. The study focuses on the variability of results between different laboratories and how the selection of assessors and the number of repetitions influence that variability. These are some key findings of the paper.
