AbstractAbout AuthorsReferences
The analysis of the normative documents regulating the inspection of the heat-protection characteristics of the enclosing structures has been carried out. It has been established that thermal imaging control of enclosing structures is a promising method, but the regulatory framework for its use needs significant revision. The authors of the article have revised the main document regulating thermal imaging inspection, GOST R 54852–2011 “Buildings and Structures. Method of thermal imaging quality control of thermal insulation of building envelopes”. The revision of GOST R 54852 was carried out with the aim of increasing the accuracy of thermal imaging examinations of the heat- protection properties of enclosing structures and expanding its scope. This article contains new provisions developed as a result of the revision of GOST. The new regulations relate to thermography of translucent and leaky enclosing structures (with air filtration). For translucent structures, the use of new provisions in some cases makes it possible to conduct the thermography at a quantitative level. A new method of processing the results of thermal imaging measurements, formulas for recalculating measurement results for design conditions and formulas for determining the measurement error are presented. New operations with the use of the air temperature reference points have been introduced into the methodology for conducting thermal imaging inspection, which make it possible to significantly increase the accuracy of the thermal imaging method. The analysis of the new provisions of GOST R 54852 was carried out with explanations and comments.
