Free hanging heating and cooling surfaces for water with a temperature below 120°C - Part 5: Test method for thermal output of open or closed heated ceiling surfaces
This European Standard describes the test method and the test installation for determining the thermal output of ceiling mounted heating surfaces according to the specifications of prEN 14037-1@ clause 3.3.2@ 3.3.3 and 3.3.4. This part applies to determine thermal output when chilled ceilings according to EN 14240 are also used for heating. NOTE Test results according to this part can not be compared with results according prEN 14037-2 because great discrepancies are given at open ceilings@ convective components and heating surfaces without upper insulation.
