EN industry Standards
As of November 2016, EN 14037-4 cooling capacity of radiant panels and EN 14037-5 thermal output of open or closed heated ceilings standards have superseded the previous standards and although not mandated, should be adopted.
EN 14037-5 – A welcome introduction
Manufacturer’s would typically have tested using EN 14037-2 thermal output of radiant panels testing methodology whether radiant panels were either installed as ceiling panels (free hanging or ceiling sails) or within a ceiling grid application.
The introduction of EN 14037-5 ensures a separate testing methodology is used for ceiling grid applications.
It’s all about active surface
With reference to EN 14037-5, the active surface is determined by calculating active length x active width. The active length takes into consideration the pipes and heat exchanger strip – whichever is longer.
The active width is derived by multiplying the number of pipes by the spacing between each of the pipes.
This differs from EN 14037-2 – for each panel there is a specific heat output in W/m, based on the dimensions of the ceiling panel.
EN 14037-2 & EN 14037-5 – Where and when should they be used
In simple terms, EN 14037-2 should be used when ceiling panels are being installed and EN 14037-5 used for ceiling grids.
What you need to do
Ensure that the manufacturers you are working with adhere to the new standards and apply the appropriate EN standard based on the type of application, be it ceiling panels or ceiling grids, that you are designing to.
Adopting the appropriate standard, will ensure a building will achieve its thermal design conditions.
