Non-destructive testing — Image quality of radiographs — Part 4: Experimental evaluation of image quality values and image quality tables
ISO 19232-4:2013 gives instructions for the determination of image quality values and image quality tables. If the IQI requirements specified in ISO 19232‑3 cannot be used because, for example, the absorption coefficients of the IQI material and the inspected material differ by more than 30 %, test exposures are necessary to determine acceptance of image quality values. The image quality values achieved by the test exposures are required for all exposures made under the same radiographic conditions.
Essais non destructifs — Qualité d'image des radiogrammes — Partie 4: Évaluation expérimentale des indices de qualité d'image et des tables de qualité d'image
L'ISO 19232-4:2013 donne les instructions pour déterminer les indices de qualité d'image et les tables de qualité d'image. S'il n'est pas possible d'appliquer à l'IQI les exigences spécifiées dans l'ISO 19232-3, parce que, par exemple, les coefficients d'absorption du matériau de l'IQI et du matériau soumis à essai diffèrent de plus de 30 %, il est nécessaire d'utiliser des expositions d'essai pour déterminer des indices de qualité d'image acceptables. Les indices de qualité d'image obtenus par les expositions d'essai sont requis pour toutes les expositions faites dans les mêmes conditions radiographiques.

Overview
ISO 19232-4:2013 is part of the ISO 19232 series, addressing non-destructive testing (NDT) and the image quality of radiographs. Specifically, this standard focuses on the experimental evaluation of image quality values and the creation of image quality tables for radiographic testing. ISO 19232-4:2013 provides a practical framework for situations where conventional requirements for image quality indicators (IQIs), as defined in ISO 19232-3, cannot be applied due to significant differences in absorption coefficients between IQI materials and the tested object.
This standard gives guidance for conducting test exposures and establishing image quality tables under varying radiographic conditions, ensuring reliable and consistent assessment of radiographic image quality in industrial applications.
Key Topics
- Image Quality Indicator (IQI) Use: Defines the use and significance of IQIs-devices with graded elements (such as wires or steps)-to measure radiographic image quality.
- Image Quality Value (IQV) Determination: Instructions for experimental procedures to establish the minimum detectable detail in a radiograph.
- Image Quality Table Creation: Directions for developing tables correlating minimum image quality values to different penetrated thickness ranges.
- Test Exposure Methodology: Outlines how to perform experimental test exposures when standard IQI criteria do not apply, including the repetition of tests for consistent results.
- Acceptance Criteria: Details the process for accepting image quality values based on repeated, reproducible measurements.
- Application Scope: Applicability when the absorption coefficient of the IQI deviates significantly (by more than 30%) from the inspected material.
Applications
ISO 19232-4:2013 is essential for various industries relying on radiographic testing to ensure material integrity and safety. Its primary applications include:
- Industrial Radiography: Used across sectors such as aerospace, automotive, construction, and energy to validate the quality of welds, castings, and structural components.
- Customized Testing Conditions: Enables radiographic testing under non-standard conditions where material properties require experimental evaluation rather than routine application of generalized indicators.
- Development of Inspection Protocols: Supports the creation of customized acceptance criteria and image quality tables for specific materials and geometries, enhancing reliability in critical assessments.
- Quality Assurance in Manufacturing: Ensures traceability and repeatability in radiographic image evaluation, which is vital for organizations needing to meet regulatory, safety, and quality standards.
Related Standards
For a comprehensive approach to image quality in radiographic testing, consider the following ISO standards alongside ISO 19232-4:2013:
- ISO 19232-1: Determines image quality value using wire-type IQIs.
- ISO 19232-2: Determines image quality value using step/hole-type image quality indicators.
- ISO 19232-3: Defines radiographic image quality classes and essential acceptance criteria.
- ISO 19232-5: Specifies the determination of image unsharpness using duplex wire-type IQIs.
- ISO 5579: Lays out the basic rules for radiographic testing of metallic materials using film and X- or gamma rays.
By implementing ISO 19232-4:2013, organizations utilize a standardized, systematic method for evaluating and documenting image quality in radiographic NDT, especially in cases that fall outside standard IQI application, ensuring both compliance and operational excellence.

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.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes
nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est
en général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l’ISO participent également aux travaux.
L’ISO collabore étroitement avec la Commission électrotechnique internationale (CEI) en ce qui concerne
la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives
ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de
Normes internationales adoptés par les comités techniques sont soumis aux comités membres pour vote.
Leur publication comme Normes internationales requiert l’approbation de 75 % au moins des comités
membres votants.
L’attention est appelée sur le fait que certains des éléments du présent document peuvent faire l’objet de
droits de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de
