Non-destructive testing of welds - General rules for metallic materials (ISO/FDIS 17635:2024)
ISO 17635:2016 gives guidelines for the choice of non-destructive testing (NDT) methods for welds and evaluation of the results for quality control purposes, based on quality requirements, material, weld thickness, welding process and extent of testing.
ISO 17635:2016 also specifies general rules and standards to be applied to the different types of testing, for either the methodology or the acceptance levels for metallic materials.
Acceptance levels cannot be a direct interpretation of the quality levels defined in ISO 5817 or ISO 10042. They are linked to the overall quality of the produced batch of welds.
Requirements for acceptance levels for NDT comply with quality levels stated in ISO 5817 or ISO 10042 (moderate, intermediate, stringent) only on a general basis and not in detail for each indication.
Annex A gives correlations between quality, NDT and acceptance level standards.
Annex B gives an overview of the standards linked to quality levels, acceptance levels and NDT methods.
Zerstörungsfreie Prüfung von Schweißverbindungen - Allgemeine Regeln für metallische Werkstoffe (ISO/FDIS 17635:2024)
Dieses Dokument gibt Leitlinien für die Auswahl zerstörungsfreier Prüfverfahren (ZfP) (NDT, en: non-destructive testing) für Schweißverbindungen in Metallen und für die Bewertung der Ergebnisse zum Zwecke der Qualitätskontrolle auf der Grundlage von Qualitätsanforderungen, Werkstoff, Schweißnahtdicke, Schweißprozess und Prüfumfang.
Dieses Dokument legt außerdem allgemeine Regeln und Normen fest, die auf die verschiedenen Prüfarten, für die Auswahl des Verfahrens, der Techniken und die Zulässigkeitsgrenzen anzuwenden sind.
Zulässigkeitsgrenzen können keine direkte Auslegung der Bewertungsgruppen nach ISO 5817 oder ISO 10042 sein. Sie stehen mit der Gesamtqualität der hergestellten Schweißnahtchargen im Zusammenhang.
Die in diesem Dokument festgelegten Anforderungen an die Zulässigkeitsgrenzen für die zerstörungsfreie Prüfung entsprechen den in ISO 5817 oder ISO 10042 genannten Bewertungsgruppen (mäßig, mittel, hoch) nur allgemein und nicht im Einzelnen für jede Anzeige.
In Anhang A sind die Zusammenhänge zwischen Bewertungsgruppen, Prüfklassen und Zulässigkeitsgrenzen für spezifische Prüftechniken angegeben.
Anhang B gibt einen Überblick über die Normen im Zusammenhang mit den Bewertungsgruppen, Zulässigkeitsgrenzen und Prüfverfahren für spezielle Prüftechniken.
Essais non destructifs des assemblages soudés - Règles générales pour les matériaux métalliques (ISO/FDIS 17635:2024)
ISO 17635:2016 donne des lignes directrices pour le choix des méthodes d'essai non destructif (END) des assemblages soudés et l'évaluation des résultats dans le cadre du contrôle qualité, en se fondant sur les exigences concernant la qualité, le matériau, l'épaisseur de soudure, le procédé de soudage et l'étendue de l'essai.
ISO 17635:2016 spécifie également les règles générales et les normes applicables aux différents types d'essai, tant du point de vue de la méthodologie que des niveaux d'acceptation pour les matériaux métalliques.
Les niveaux d'acceptation ne peuvent pas être une interprétation directe des niveaux de qualité définis dans l'ISO 5817 ou l'ISO 10042. Ils sont liés à la qualité globale du lot d'assemblages soudés produit.
Les exigences relatives aux niveaux d'acceptation pour les END ne sont corrélées aux niveaux de qualité définis dans l'ISO 5817 ou l'ISO 10042 (modérés, moyens et élevés) que sur une base générale, et non pas en détail pour chaque indication.
L'Annexe A établit une corrélation entre les normes relatives à la qualité, aux essais non destructifs et aux niveaux d'acceptation.
L'Annexe B donne une vue d'ensemble des normes relatives aux niveaux de qualité, aux niveaux d'acceptation et aux méthodes d'essai non destructif.

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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 5, Testing and inspection of welds.
This fourth edition cancels and replaces the third edition (ISO 17635:2016), which has been technically
revised.
The main changes are as follows:
— references updated;
— Phased-array ultrasonic technique (UT-PA) for thin-walled steel components added;
— Total focusing technique (TFM) added.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Non-destructive testing of welds — General rules for
metallic materials
1 Scope
This document gives guidelines for the choice of non-destructive testing (NDT) methods for welds in
metals and for the evaluation of the results for quality control purposes, based on quality requirements,
material, weld thickness, welding process and extent of testing.
This document also specifies general rules and standards to be applied to the different types of testing,
for the selection of the method, the techniques and the acceptance levels.
Acceptance levels cannot be a direct interpretation of the quality levels defined in ISO 5817 or
ISO 10042. They are linked to the overall quality of the produced batch of welds.
Requirements for acceptance levels for NDT comply with quality levels stated in ISO 5817 or ISO 10042
(moderate, intermediate, stringent) only on a general basis and not in detail for each indication.
Annex A gives correlations between quality levels, testing levels and acceptance levels for specific
testing techniques.
Annex B gives an overview of the standards linked to quality levels, acceptance levels and testing
methods for specific testing techniques.
