Introduction
This European Standard results from the recognition that the ceiling mounted heating and cooling surfaces falling
into the field of application hereinafter stated are traded of the basis of their thermal and cooling output. For evalu-
ating and comparing different ceiling mounted radiant panels it is therefore necessary to refer to a single stipulated
value.
The European Standard EN 14037, Free hanging heating and cooling surfaces for water with a temperature below
120°C consists of the following parts:
- Part 1: Technical specifications and requirements
- Part 2: Test method for thermal output of ceiling mounted radiant panels
- Part 3: Rating method and evaluation of radiant thermal output of ceiling mounted radiant panels
- Part 4: Test method for cooling capacity of ceiling mounted radiant panels
- Part 5: Test method for thermal output of open or closed heated ceiling surfaces
1 Scope
This European Standard defines the technical specifications and requirements of ceiling mounted radiant panels,
heating and cooling surfaces fed with water at temperatures below 120 °C connected with a centralized heating
and/or cooling supply source.
The European Standard does not apply to independent heating and/or cooling devices.
The European Standard also defines the additional common data that the manufacturer shall provide to the trade in
order to ensure the correct application of the products.
2 Normative references

5 Construction specifications
5.1 General construction specifications
The thermal output of a ceiling mounted radiant panel is mainly transferred downwards to the space by radiation.
The thermal output upwards shall be minimized by insulation.
The maximum surface temperature of the lateral edges shall not exceed the minimum surface temperature of the
radiant sheet between the last two wet surfaces. For ceiling panels with a construction according to Figure 1 with a
tube pitch of X (mm), the distance between the axis of the outside tubes and the edges has to have a minimum
distance of 0,5X (mm).
The panel is freely suspended above the useful space and designed to be a permanent part of the building al-
though not a part incorporated in the building structure
Air flow across the panel is to be prevented.
