Working Group 41 of CEN Dealing with IOMSs Met in Paris (and Online) on June 16th, 2025

   Working Group 41 of CEN convened in Paris (and online) on 16 June this year, with the main focus on resolving comments made to the drafts of Part 1 and Part 2 of the standard for Instrumental Odour Monitoring Systems (IOMS). Part 1 will deal with definitions and general aspects, Part 2 will address technical specifications and QA/QC requirements, and Part 3 will cover field validation. This is the second attempt by Working Group 41, following an earlier effort that was not successful.

   A week ago, the WG41 group gathered in Paris to discuss the progress of the two drafts currently in development. The group has been working for over three years on the first CEN standard for Instrumental Odour Monitoring Systems. On this occasion, the group reviewed around 150 comments, with over 110 coming from the Spanish mirror group.

   The first draft focuses on terms and definitions for instrumental odour monitoring systems, while the second draft covers technical specifications and QA/QC requirements. This Paris meeting marked the second review of these drafts, and although a few comments remain unresolved, the majority of the work is now complete.

   Parts 1 and 2 have completed the drafting process, while Part 3, dealing with field validation, is still in progress.

   The next meeting of Working Group 41 is scheduled to take place in Madrid, dates to be confirmed yet.
