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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
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.
ISO 19232-1 was prepared by the European Committee for Standardization (CEN) in collaboration with
ISO Technical Committee TC 135, Non-destructive testing, Subcommittee SC 5, Radiation methods, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 19232-1:2004), of which it constitutes a
minor revision with the following changes:
— update of references and definitions;
[1]
— statement that EN wire IQIs of EN 462-1:1994 and its designation are identical with ISO wire IQIs
and its designation, as defined in this part of ISO 19232;
— replacement of film by detector, which includes film and digital detectors;
— addition of a new Annex for conversion of ASTM wire IQI identities to ISO wire IQI numbers.
It also incorporates the Technical Corrigendum, ISO 19232-1:2004/Cor. 1:2007.
ISO 19232 consists of the following parts under the general title Non-destructive testing — Image quality
of radiographs:
— Part 1: Determination of the image quality value using wire-type image quality indicators
— Part 2: Determination of the image quality value using step/hole-type image quality indicators
— Part 3: Image quality classes
— Part 4: Experimental evaluation of image quality values and image quality tables
— Part 5: Determination of the image unsharpness value using duplex wire-type image quality indicators

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
image quality
characteristic of a radiographic image which determines the degree of detail it shows
3.2
image quality indicator
IQI
device comprising a series of elements of graded dimensions which enable a measure of the image
quality to be obtained
Note 1 to entry: The elements of IQI are commonly wires or steps with holes.
3.3
image quality value
measure of the image quality required or achieved and is equal to the thinnest element which can be
detected on the radiograph
Note 1 to entry: For wire-type IQIs, the element numbers are given in Table 1.

Figure 1 — Image quality indicator (wire-type)
The IQI system is based on a series of 19 wires of different diameters which are specified in Table 1
together with the relevant tolerances and the wire numbers. This series of wires has been subdivided
into four overlapping ranges of seven consecutive wire numbers, viz. W 1 to W 7, W 6 to W 12, W 10 to
W 16, and W 13 to W 19. The seven wire
