EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 12939 testing. This standard specifies procedures for determining the thermal resistance of products whose thickness exceeds the maximum thickness for enclosed hot plate or heat flow meter apparatus.
In any event, most of the procedures described in this standard require apparatus that allow testing on samples up to 100 mm thick. This standard gives guidelines for assessing the importance of the thickness effect, ie determining whether the thermal resistance of a thick product can be calculated as the sum of the thermal resistances of slices cut from the product. This standard describes test conditions that prevent the onset of convection.
Sample preparation and processing shall comply with EN 12667. Specific sample preparation should be contained in the appropriate product standard that refers to the procedures described in this standard.
The purpose of this standard is to determine the thermal resistance of building materials and products, especially with high and medium thermal resistance, using two different methods: the shielded hot plate method and the heat flow meter method.
The thermal resistance of a material indicates its ability to resist heat flow or conductive heat transfer. It is a very important parameter for evaluating the energy efficiency and thermal performance of building materials such as insulation products, wall panels and roofing materials.
By following the procedures outlined in EN 12939, manufacturers, testing laboratories and other stakeholders can accurately determine the thermal resistance of thick building materials and products with high and medium thermal resistance.
