Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

Introduction
The industrial applications of infrared thermographic testing in non-destructive testing (NDT) are
growing, along with a remarkable improvement in thermographic technologies. The effectiveness of any
application of infrared thermographic testing depends upon proper and correct usage of the method.
The purpose of this document is to provide general principles for infrared thermographic testing in
order to promote the correct and effective application of a variety of industrial NDT, such as in power
plants, buildings and structures, electronic instruments and industrial materials.

Non-destructive testing — Infrared thermographic testing
— General principles
1 Scope
This document provides general principles for infrared thermographic testing in the field of industrial
non-destructive testing (NDT).
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 9712, Non-destructive testing — Qualification and certification of NDT personnel
ISO 10878, Non-destructive testing — Infrared thermography — Vocabulary
3 Terms and definitions
For the purposes of this document the terms and definitions given in ISO 10878 apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at http:// www .electropedia .org/
— ISO Online browsing platform: available at http:// www .iso .org/ obp
4 Infrared thermographic testing personnel
Personnel who are responsible for conducting infrared thermographic testing (TT) shall meet the
following criteria.
a) TT personnel shall have an adequate knowledge of the basics of infrared measurement and heat-
transfer engineering as required by ISO 9712.
b) The TT personnel’s visual acuity and colour vision shall meet the requirements of ISO 9712.
5 Infrared thermographic testing equipment
5.1 Infrared camera
Each infrared camera has different properties and functions, such as the type of infrared detecting
device, the spatial resolution (instantaneous field of view, effective pixels), temperature range,
temperature resolution, temperature accuracy, frame time, exposure time, detection wavelength range,
cooling method, scanning method, and the visible image display and recording function. It is necessary
to ensure that an infrared camera with appropriate properties and functions with appropriate
temperature calibration to meet the purpose of the testing is used.
If necessary, various devices that can be attached to the infrared camera such as wavelength filters,
attenuation filters, replacement lenses, monitors, computers and software for data collection and
processing, and infrared-reflecting mirrors may be used.

5.2 Equipment used for active thermography
Select the appropriate heating or cooling system, taking into account the properties and functions of the
infrared camera, the test environment, and the status of the test object (dimensions, shape, emissivity,
material, temperature before thermal loading, and so on.)
