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
rules given in the ISO/IEC Directives, Part 2. 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. www.iso.org/patents
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
The committee responsible for this document is ISO/TC 135, Non-destructive testing, Subcommittee
SC 5, Radiation methods.
This third edition cancels and replaces the second edition (ISO 5579:1998), which has been
technically revised.
Changes from the second edition include:
— introduction of film in the title — this International Standard is valid only for NDT films as image
detectors and not for digital radiographic detectors;
— reference to the state-of-the-art image quality detectors, according to ISO 19232-1 to ISO 19232-4;
— omission of figures with test arrangements (these test arrangements are described in the
corresponding application standards);
— extension of applicable X-ray voltages from 500 kV up to max. 1 000 kV, depending on the penetrated
wall thickness and material;
— modification of the nomogram of minimum source distances for focal spot sizes from 0,1 mm up to
8 mm;
— update of film system classes (old ISO classes T2 and T3 have been replaced by new classes C3 to C5,
according to ISO 11699-1:2008);
— several editorial changes.

Introduction
This International Standard specifies fundamental techniques of radiography, with the object of enabling
satisfactory and repeatable results to be obtained economically. The techniques are based on generally
accepted practice and the fundamental theory of the subject.
Standards relating to specific applications should conform to these basic rules.
