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.<\/p>\n
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.<\/p>\n
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 \u2018test protocols\u2019.<\/p>\n
This revised document was drawn up by nominated international experts of the International VERA Committee (IVC) for Air Cleaning Systems:<\/p>\n
