Revised VERA test protocol ‘Air Cleaners’ finalised

17 September

Of all the emission reducing technologies in agriculture, air cleaners are probably the most regulated in the different countries, a situation that posed a particular challenge for achieving common agreements during the revision of this VERA test protocol. In this regard, the task here was to formulate a test protocol with measurements that would fit the requirements of all three countries and reflect the latest state-of-the-art.

The new document indicates the requirements and recommendations much more precisely, especially with regard to the description of sampling and testing certain parameters, and provides a more detailed description of data treatment and calculation of different parameters, such as emissions and N balances.

Now, after final approval of the VERA Board, it is ready for publication. We are glad that the revised version is now available for free download on our sub-page ‘test protocols’.

This revised document was drawn up by nominated international experts of the International VERA Committee (IVC) for Air Cleaning Systems:

For Denmark:

Anders Feilberg, Aarhus University

Michael Jørgen Hansen, Aarhus University

For Germany:

Jochen Hahne, Thünen Institute

Volker Siemers, DLG

For the Netherlands:

Roland Melse, WUR

Nico Ogink, WUR

Many thanks to these VERA experts for their effort and their excellent work on this particularly challenging task!
