The moment finally arrived and here you have the new EN 13725:2022 finally published. As many of you know, the European standard was published first in 2003. Four years later in 2007 the doc was revisited, and no changes were made. Another four years later in 2011 the working group (WG) dealing with this standard considered that it was time to review the text profoundly and the 20th of November 2012 the first meeting took place.

   After 17 meetings and 9 years, this European standard is finally published and available for everyone. Most of the work carried out has been targeted to address uncertainty, and concepts like the Secondary Odour Reference Mass (SROM) have been introduced in the new text. But this is not the only change, you probably know that many, many other things have been discussed along the years.

   This standard has a long history, and it has been successfully applied in many countries around the world. In Europe, the Industrial Emissions Directive found a perfect fit in cases where no regulatory approaches were set in place. In countries like Australia, Chile, Colombia, USA, South Korea or New Zealand, this standard has been taken as a reference in many cases to try to regulate the odour impact in cases where nothing else was available in the past.

 The amount of changes is such, that it is very difficult to comment them in a single article. Maybe this talk given by the convenor of the Working Group 2 (WG2), Ton van Harreveld, could be a good starting point for beginners.

   If you are eager to buy this standard, here you have a list of countries that have already published the new EN 13725:2022 standard. Enjoy it!
