This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the
room to be heated or to be cooled.
This document deals with the use in practical engineering of the results coming from part 2 and 5 and is
applicable to floor-, ceiling- and wall heating systems, as well floor-, ceiling- and wall cooling systems.
For heating systems, physiological limitations are taken into account when specifying the surface
temperatures. In the case of floor heating systems the limitations are realised by a design based on the
characteristic curves and limit curves determined in accordance with part 2 of this Standard.
For cooling systems, only a limitation with respect to the dew point is taken into account. In predominating
practice, this means that physiological limitations are included as well.
