Non-destructive testing of welds - Magnetic particle testing (ISO 17638:2003)
This International Standard specifies techniques for detection of surface imperfections in welds in ferromagnetic materials, including the heat affected zones, by means of magnetic particle testing. The techniques are suitable for most welding processes and joint configurations. Variations in the basic techniques that will provide a higher or lower test sensitivity, are described in Annex A. This International Standard does not specify acceptance levels of the indications. Further information on acceptance levels for indications may be found in EN 1291 or in product or application standards.
Zerstörungsfreie Prüfung von Schweißverbindungen - Magnetpulverprüfung (ISO 17638:2003)
Diese Internationale Norm legt Techniken zum Nachweis von Unregelmäßigkeiten in der Oberfläche von ferromagnetischen Schweißnähten, einschließlich der Wärmeeinflusszonen, durch Magnetpulverprüfung fest. Diese Techniken sind für die meisten Schweißverfahren und Verbindungsarten geeignet. Variationen dieser grundlegenden Techniken mit höherer oder niedriger Prüfempfindlichkeit sind im Anhang A beschrieben.
Diese Internationale Norm legt keine Zulässigkeitsgrenzen für die Anzeigen fest. Weitere Informationen bezüglich Zulässigkeitsgrenzen für Anzeigen können entweder in EN 1291 oder in Produkt oder Anwendungsnormen gefunden werden.
Contrôle non destructif des assemblages soudés - Contrôle par magnétoscopie (ISO 17638:2003)
L'ISO 17638:2003 spécifie les méthodes pour la détection par contrôle par magnétoscopie des défauts de surface des soudures de matériaux ferromagnétiques, y compris les zones affectées thermiquement, à l'aide de la méthode de magnétisation par passage de courant. Les techniques sont appropriées pour la plupart des procédés de soudage et des configurations d'assemblages.
Neporušitveno preskušanje zvarnih spojev - Preskušanje z magnetnimi delci (ISO 17638:2003)
Ta mednarodni standard določa tehnike za detekcijo površinskih nepravilnosti zvarnih spojev na feromagnetnih materialih, vključno s toplotno vplivanimi področji, z uporabo preskušanja z magnetnimi delci. Tehnike so primerne za večino varilnih postopkov in konfiguracij spojev. Spremembe osnovnih tehnik, ki omogočajo večjo ali manjšo občutljivost preskusa, so opisane v Dodatku A. Ta mednarodni standard ne določa stopenj sprejemljivosti indikacij. Dodatne informacije o stopnjah sprejemljivosti za indikacije so navedene v EN 1291 ali v standardih proizvoda ali uporabe.

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 17638 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 5, Testing and inspection of welds.

d) state of manufacture;
e) testing techniques to be used;
f) overall performance test;
g) any demagnetization;
