The 18th meeting of CEN/TC 264/WG 41 that is dealing with the new standard on Instrumental Odour Monitoring Systems (IOMS) took place last 28^th of September. This was a short meeting to discuss some approaches for quality assurance and a call for volunteers to provide data to find out the best way to set a robust confidence interval for IOMSs. 

   After the last meeting discussions, it was clear that a plausibility check with real data was needed in order to test if the Chebyshev's inequality was appropriate as QAL1 procedure for IOMSs. Unfortunately, not enough data are available at this stage and no decision have been taken on this regard. The group is looking for more data on IOMS vs olfactometry tests to validate the statistical approach suggested, so anyone interested in contributing here may contact the task group leader to provide those data under a NDA.

The 27th of August 2020 took place the kickoff meeting of the group dealing with the development of the first international guideline on the assessment of odour exposure by using dispersion modelling. To date, there are already 36 professionals from Belgium, Italy, France, Chile, Ecuador, Australia, Brazil, United Kingdom, Ireland, China, Spain, USA, India, Peru, Qatar and Austria participating in this initiative.

   This development is being led by Dr. Günther Schauberger, professor of the University of Veterinary Medicine of Vienna,  and Ms. Jennifer Barclay, principal scientist of Atmospheric Science Global (ASG) in New Zealand. The list of volunteers in this initiative at this stage is the following:
