Zerstörungsfreie Prüfung - Qualifizierung und Zertifizierung von Personal der zerstörungsfreien Prüfung (ISO/FDIS 9712:2021)

Dieses Dokument legt Anforderungen an die Qualifizierung und Zertifizierung von Personal, das industrielle zerstörungsfreie Prüfungen (ZfP) in den folgenden Verfahren ausführt, fest:
a) Schallemissionsprüfung;
b) Wirbelstromprüfung;
c) Thermografieprüfung;
d) Dichtheitsprüfung (ausgenommen Wasserdruckprüfung);
e) magnetische Prüfung;
f) Eindringprüfung;
g) Durchstrahlungsprüfung;
h) Dehnungsmessstreifenprüfung;
i) Ultraschallprüfung;
j) Sichtprüfung (ausgenommen direkte Sichtprüfungen ohne Hilfsmittel und Sichtprüfungen, die während der Anwendung eines anderen ZfP-Verfahrens durchgeführt werden).
Das in diesem Dokument festgelegte System ist auch auf andere ZfP-Verfahren oder ZfP-Techniken innerhalb eines bestehenden ZfP-Verfahrens anwendbar, wenn ein umfassendes Zertifizierungsprogramm existiert und das ZfP-Verfahren oder die ZfP-Technik durch internationale, regionale oder nationale Normen abgedeckt ist oder das ZfP-Verfahren oder die ZfP-Technik zur Zufriedenheit der Zertifizierungsstelle als wirksam nachgewiesen wurde.
ANMERKUNG 1 Der Begriff „industriell“ bedeutet den Ausschluss von Anwendungen auf dem Gebiet der Medizin.
ANMERKUNG 2 CEN/TR 14748 enthält Hinweise zur Vorgehensweise für die Qualifizierung von zerstörungsfreien Prüfungen.
ANMERKUNG 3 Dieses Dokument legt praktisch die Anforderungen an Konformitätsbewertungssysteme von unabhängigen Prüfstellen fest. Diese Anforderungen gelten nicht unmittelbar für die Konformitätsbewertung durch Lieferanten oder interne Stellen, aber auf zutreffende Abschnitte dieses Dokuments kann in solchen Begutachtungen verwiesen werden.
ANMERKUNG 4 Der Begriff „direkte Sichtprüfung ohne Hilfsmittel“ bedeutet, dass der Strahlengang vom Auge des Betrachters zum Prüfbereich nicht unterbrochen ist und der Betrachter keine Werkzeuge oder Vorrichtungen (z. B. Spiegel, Endoskop, Faseroptik) verwendet.
ANMERKUNG 5 Dehnungsberechnungen auf der Grundlage anderer ZfP-Verfahren sind ausgeschlossen.

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

Introduction

Since the effectiveness of any application of non-destructive testing (NDT) depends upon the

capabilities of the persons who perform or are responsible for the test, a procedure has been developed

to provide a means of evaluating and documenting the competence of personnel whose duties require

the appropriate theoretical and practical knowledge of the non-destructive tests they perform, specify,

supervise, monitor or evaluate. An added incentive stems from the worldwide comparability of a wide

range of industrial applications requiring common non-destructive testing approaches.

When certification of NDT personnel is required in product standards, regulations, codes or

specifications, it is important to certify the personnel in accordance with this document. When

latitude is provided in the criteria within this document, the certification body has the final decision in

determining specific requirements.

When there is no requirement in legislation, in standard or in the order for certification of NDT

personnel, it is for employers of such personnel to decide how to assure themselves that they are

competent to do the work assignments. Thus, they may employ people who are already certified or

they may apply their own expertise so as to assure themselves that their employee has the necessary

competence. In this last case, prudent employers would no doubt use this document as a reference

document.

DRAFT INTERNATIONAL STANDARD ISO/DIS 9712:2021(E)
Non-destructive testing — Qualification and certification of
NDT personnel
1 Scope

This document specifies requirements for the qualification and certification of personnel who perform

industrial non-destructive testing (NDT) in the following methods.
a) acoustic emission testing;
b) eddy current testing;
c) thermographic testing;
d) leak testing (hydraulic pressure tests excluded);
e) magnetic testing;
f) penetrant testing;
g) radiographic testing;
h) strain gauge testing;
i) ultrasonic testing;

j) visual testing (direct unaided visual tests and visual tests carried out during the application of

another NDT method are excluded).

The system specified in this document is also applicable to other NDT methods or to NDT techniques

within an established NDT method, provided a comprehensive scheme of certification exists and the NDT

method or NDT technique is covered by International, regional or national standards or the NDT method

or NDT technique has been demonstrated to be effective to the satisfaction of the certification body.

NOTE 1 The term "industrial" implies the exclusion of applications in the field of medicine.

NOTE 2 CEN/TR 14748 provides guidance for methodology for qualification of NDT systems.

NOTE 3 This document specifies requirements for what are, in effect, third party conformity assessment

schemes. These requirements do not directly apply to conformity assessment by second or first parties, but

relevant parts of this document can be referred to in such arrangements.

NOTE 4 The term “direct unaided visual testing” implies where there is an uninterrupted optical path from

the observer’s eye to the test area and the observer uses no tools or devices (e.g. mirror, lens, endoscope, fibre

optic, etc…).
NOTE 5 Calculations of strain based on other NDT methods are excluded.
