On the 20th of November 2012 the first meeting took place of Working Group 2, tasked by CEN/TC274 “Air Quality” to revise EN 13725:2003 ‘Air Quality - Determination of odour concentration by dynamic olfactometry’. After 8 years of work and 17 meetings, the work is finally completed and submitted for formal vote in the CEN Technical Committee 264 “Air Quality” in 2021. This paper describes some of the important changes that will affect the practice of olfactometry in Europe, once this standard is published as EN 13725:2021.
