Thermography is a qualitative method for detecting ther-mal irregularities including air tightness, in the external envelope of buildings.
In this standard two forms of thermography are specified:
Testing with an IR-camera is primarely intended for the inspection of the over-all performance or execution of new buildings or the result after a rebuilding operation.
Simplified testing with an IR-camera is suitable when carry-ing out audits, e.g. at the prospect of a rebuilding project or at so called internal inspection.
Principally these two adaptions differ with regard to the reporting and the presentation of results.
The results obtained by means of thermography have to be interpreted and assessed by persons who are specially trained for this purpose. (See annex D.)
This International Standard does not apply to the deter-mination of the degree of thermal insulation and air tightness of a structure. For such determinations, examinations by other methods are required.
