Radiators and convectors intended for installation in central heating systems in residential buildings are tested in closed test booths in our test laboratory with water-carrying enclosures according to EN 442-2. The test results are recognised by European certifiers such as RAL, Eurovent Certita, BSI, DIN CERTCO and AENOR for the respective national quality marks, based on the international RADMAC (Radiators Mutual Acceptance of Certification) Agreement of June 2001.

Under European Regulation 305/2011, all radiators and convectors installed in the territory of the EU require a CE marking that includes a thermal performance test by a notified laboratory. We have been accredited to test radiators and convectors by the DIBt.

The tests include:

  •    Standard thermal output and characteristic curve of the thermal output
  •    Compressive strength
  •    Dimensional accuracy
  •    Pressure drop of water flow (upon request)
  •    Compressive strain test (Essais de tenue mécanique) to acquire the French NF marking and the Spanish quality marking 

Since 2015, it has also been possible to test fan-assisted radiators, convectors and underfloor convectors according to EN 16430-1-2-3 with regard to thermal output in our closed test booths in accordance with EN 442-2.

Two test beds according to EN 442-2 are available to test the thermal output of radiators and convectors. A test bed is comprised of an accessible double-walled test booth made of flat steel tubes, 4m x 4m x 3m in size. All the six surfaces surrounding the booth carry water and can be maintained at a constant temperature through a closely controlled supply circuit. Fan-assisted convectors can also be measured with regard to cooling capacity according to EN 16430. The cooling loads are introduced into the booth by means of mobile, controlled heat sources (person simulators).

The test unit is placed on a wall and connected to a water-carrying measuring cycle. The water of the measuring cycle can be heated. The thermal output introduced via the test unit is dissipated via the enclosures.
