Thermal performance of windows and doors - Determination of thermal transmittance by hot-box method - Part 1: Complete windows and doors (ISO 12567-1:2010)
SS-EN ISO 12567-1:2010/AC:2010
This part of ISO 12567 specifies a method to measure the thermal transmittance of a door or window system. It is applicable to all effects of frames, sashes, shutters, blinds, screens, panels, door leaves and fittings.
It is not applicable to
- edge effects occurring outside the perimeter of the specimen,
- energy transfer due to solar radiation on the specimen,
- effects of air leakage through the specimen, and
- roof windows and projecting products, where the external face projects beyond the cold side roof surface.
NOTE For roof windows and projecting units, see the procedure given in ISO 12567-2.
Annex A gives methods for the calculation of environmental temperatures.
