ISO 6781-1 specifies requirements and methodologies for infrared thermographic services for the detection of heat, air and moisture irregularities in buildings that help users to specify and understand:
— the extent of thermographic services required,
— the type and condition of equipment available for use,
— the qualifications of equipment operators, image analysts, and report authors and those making recommendations, and
— the reporting of results.
Infrared building thermography provides a tool to qualitatively identify the presence of energy-wasting defects and anomalies within building structures. These defects and anomalies can include, for example, thermal insulation defects, moisture content, or unwanted air movement or leakage within the building enclosure.
ISO 6781-1 applies to the general procedures for infrared thermographic methods and can be applied to residential, commercial, institutional and special-use buildings. These methodologies can be used for either new-construction quality control applications or in existing buildings as ongoing condition monitoring for periodic or specific building-condition reporting. The latter applications may be accompanied by visual fault symptoms, while the former may not necessarily present symptoms via visual faults.
The text of ISO 6781-1:2023 has been approved in Europe as EN ISO 6781-1:2023 without any changes.
