Non-destructive testing of welds - General rules for metallic materials (ISO 17635:216)
This document 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.
This document 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.

Contrôle non destructif des assemblages soudés - Règles générales pour les matériaux métalliques (ISO 17635:2016)
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.
Neporušitveno preskušanje zvarov - Splošna pravila za kovinske materiale (ISO 17635:2016)
Ta dokument podaja smernice za izbiro metod neporušitvenega preskušanja (NDT) za zvare in
vrednotenje rezultatov za namene nadzora kakovosti na podlagi zahtev glede kakovosti, materiala, debeline zvara, postopka varjenja in obsega preskušanja.
Ta dokument določa tudi splošna pravila in standarde, ki se uporabljajo za različne vrste preskušanja, za metodologijo ali stopnje sprejemljivosti kovinskih materialov.
Stopnje sprejemljivosti ne pomenijo neposredne razlage stopenj kakovosti, opredeljenih v standardu ISO 5817 ali ISO 10042. Te so povezane s splošno kakovostjo proizvedene serije zvarov.
Zahteve za stopnje sprejemljivosti za neporušitveno preskušanje so v skladu s stopnjami kakovosti, navedenimi v standardu ISO 5817 ali ISO 10042 (zmerna, srednja, stroga), le na splošno in ne podrobno za vsako indikacijo.
Dodatek A podaja korelacije med standardi glede kakovosti, neporušitvenega preskušanja zvarov in stopnjami sprejemljivosti.
Dodatek B podaja pregled standardov, povezanih s stopnjami kakovosti, stopnjami sprejemljivosti in metodami neporušitvenega preskušanja.

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 on 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 the following URL: www.iso.org/iso/foreword.html.
The committee responsible for this document is ISO/TC 44, Welding and allied processes, Subcommittee
SC 5, Testing and inspection of welds.
This third edition cancels and replaces the second edition (ISO 17635:2010), which has been technically
revised. Notably, it has been changed as follows:
— International Standards have replaced European standards as normative references;
— “examined” has been replaced by “tested” in the whole document;
— important modifications have been made to Annex A, Rules and standards to be applied;
— Annex C, Non-acceptable indications, has been deleted.
Requests for official interpretations of any aspect of this International Standard should be directed to
the Secretariat of ISO/TC 44/SC 5 via your national standards body. A complete listing of these bodies

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 17635 was prepared by the European Committee for Standardization (CEN) Technical Committee TC
