wg41 meeting bilbao 2019 2The 13th meeting of the Working Group (WG) 41 of the Technical Committee (TC) 264 on air quality of the European Standard Committee (CEN) dealing with Instrumental Odour Monitoring Systems (IOMS) coded as CEN/TC 264/WG 41, took place in Bilbao, Spain the 3rd and 4th of July. A total of 16 experts met to discuss the new standard on IOMSs, previously known as e-noses.

A new Task Group 5 (TG5) was created in the previous meeting in Milan in order to deal with the implications of the standards on Automatic Measuring Systems (AMS) EN 141881 and EN 15267, on IOMSs. Among the many issues addressed in this meeting in Bilbao, a new proposal to bring a Quality Assurance Level (QAL) 1 was discussed.

A new standard on an Annoyance Benchmark?

However, this methodology has serious limitations. For example, they lack precision on recording time and location stamp of an incident. That is why a group of experts from Spain have decided to work on a new methodology to map annoyance based on citizen science and other tools. Second meeting of this group that discusses about  linking an Odour Impact Critera to an Annoyance Benchmark took place last week. The idea behind is to work together with the Spanish Accreditation Body (UNE) to publish the first standard on this subject.

   Odour Impact Criteria (OIC) set in many parts of the world, are based on dose-response psychometric studies made in Germany and the Netherlands many years ago. Nowadays, with the use of smartphones it is possible to instantaneously record time and location of an odour perception. This is a better way to assess the impact and the only way to link odour with annoyance, that is why a group of experts has met to write the first standard on annoyance mapping.

Working group 41 on IOMS has got an extension to continue its work.

wg41   The Technical Committee 264 (TC264) on Air Quality has decided to grant an extension to the work developed by the experts on Working Group 41 (WG41) focused on Instrumental Odour Monitoring Systems (IOMS) by activating a work item. That means that the group will have 3 more years to develop this standard.

   The first meeting of this group took place three and a half years ago in Antwerp, Belgium. Much work has been done during this time by the around 15 experts that usually meet in these 2-days sessions that are hold usually three times a year. In addition, there are also Task Group meetings planned around the year and videomeetings hold from time to time. So there is a lot of work and a lot of hours here to develop a standard.
