EVS-EN 13187:2001

This standard specifies a qualitative method, by thermographic examination, for detecting thermal irregularities in building envelopes. The method is used initially to identify
wide variations in the thermal properties, including air tightness, of the components constituting the external envelopes of buildings.
The results obtained by means of this method have to be interpreted and assessed by persons who are specially trained for this purpose.
The standard does not apply to the determination of the degree of thermal insulation and air tightness of the structure.
