Revised VERA test protocol ‘Air Cleaners’ finalised

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’ or directly here:
VERA test protocol ‘Air Cleaning Systems’ (PDF, 627 kB).

 

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!
