New certification scheme for thermostatic radiator valves according to EN 215 published


thermostatic radiator valve

For many years, the planners and installers domestically and in other countries have been relying on the KEYMARK certification for thermostatic radiator valves and the “KEYMARK".in accordance with EN 215. Whether in Europe or Asia, the KEYMARK certificate opens up access to local markets worldwide for you.

But even good things can get better. The responsible standards committee NA 041-03-60 AA within the DIN Deutsches Institut für Normung e. V. has revised EN 215. The valid version was published in December 2019. It resulted in the following main changes in comparison with the previous version 2007-11 in addition to an editorial revision.

Overview of the main changes

  • New CA value calculation according chapter A.7
  • New sensor temperature at the minimum and maximum setting without the minimum limit at max. 12 °C according chapter 5.3.4
  • New resistance of the temperature selector to a torque. The torque was reduced from 8 Nm to 7 Nm.

We have incorporated these changes together with the European certification committee CCC3-KEYMARK into the KEYMARK certification scheme “Thermostatic radiator valves" (edition 4: 2020-02).

It is possible to access this as a PDF document on our website at www.dincertco.de . You will also find the current application documents for the certification including the valid schedule of fees as well as all valid certificate holders.

Overview of the main changes

  • The new CA value must be calculated and published by the manufacturer.
  • The CA value must be disclosed to the responsible testing/inspection authority before the next inspection.
  • Editorial changes

What concrete changes will there be for you?

  • The new certification scheme is to be applied bindingly for all new thermostatic radiator valves to be tested for which the KEYMARK is to be applied.
  • All existing KEYMARK certificates, which are based on the current certification scheme (as of: 2014-01) must be converted to the new certification scheme no later than 2021-01. On application, however, this can also be done beforehand.
  • Inspection, modification, or extension of KEYMARK-certified products must be performed in accordance with the new certification scheme.
  • Please ensure that the test and inspection report also refers to the valid certification scheme incl. issue date.
  • Furthermore, in order to minimize the processing time, the testing laboratory should send you and us all the necessary reports directly as a PDF file.

We are ready. Our experts know the changes in detail and are happy to answer your specific questions.
