CE tests according to EN 12566

The basis for a successful market entry in Europe is the CE marking of your product. For this purpose, the series of standards – EN 12566 – is used. Five of the seven standards have been harmonised and, with our support, you can receive a declaration of performance according to one of these standards and place it on your product. With it, small wastewater treatment plants can be traded legally throughout Europe.

The standard EN 12566 is divided into several parts, each of which defines the basis for the respective tests:

Lecture: New storm water treatment

Lecture on the current topic:

Performance and testing of decentralized stormwater treatment systems“

The progressive sealing of land and anthropogenic contamination require solutions in the field of stormwater treatment. Nearby treatment and infiltration help to relieve hydraulically stressed drainage systems, contribute to the restoration of the natural water balance and take targeted action at the point of pollution. Decentralized stormwater treatment plants can offer an alternative.

In Germany, but also in other countries, requirements are already being placed on these systems and they are being tested under laboratory conditions. The presentation shows the current problems, gives an overview of the different treatment systems and their possible applications, and presents the test requirements and the tests itself.
