Non-destructive testing - Qualification and certification of NDT personnel - General principles (ISO 9712:2012)
This International Standard specifies requirements for principles for the qualification and certification of personnel who perform industrial non-destructive testing (NDT).
Zerstörungsfreie Prüfung - Qualifizierung und Zertifizierung von Personal der zerstörungsfreien Prüfung - Allgemeine Grundlagen (ISO 9712:2012)
Diese Internationale Norm legt Grundsätze für die Qualifizierung und Zertifizierung von Personal fest, das industrielle zerstörungsfreie Prüfungen (ZfP) durchführt.
ANMERKUNG 1 Der Begriff „industriell“ bedeutet den Ausschluss der Anwendung in der Medizin.
Das in dieser Internationalen Norm beschriebene System darf auch für andere ZfP-Verfahren, oder neue Techniken innerhalb bestehender ZfP-Verfahren angewendet werden, vorausgesetzt, es besteht ein Zertifizierungsprogramm und das Verfahren oder die Technik wird in Internationalen, Europäischen oder Nationalen Normen behandelt.
Die Zertifizierung schließt die Vertrautheit mit der Anwendung eines oder mehrerer der folgenden Verfahren ein:
a) Schallemissionsprüfung;
b) Wirbelstromprüfung;
c) Infrarotthermografie;
d) Dichtheitsprüfung (ausgenommen Wasserdruckprüfungen);
e) Magnetische Prüfung (Magnetpulverprüfung und Streuflussprüfung);
f) Eindringprüfung;
g) Durchstrahlungsprüfung;
h) Zugprüfung;
h) Ultraschallprüfung;
i) Sichtprüfung (ausgenommen direkte Sichtprüfungen ohne Hilfsmittel und Sichtprüfungen, die während der Anwendung eines anderen ZfP-Verfahrens durchgeführt werden).
Zertifizierung nach dieser Internationalen Norm bestätigt die generelle Kompetenz eines ZfP-Prüfers. Sie stellt keine Autorisierung für die Durchführung der Tätigkeiten dar, da diese Verantwortung beim Arbeitgeber verbleibt und der zertifizierte Angestellte weitere spezielle Kenntnisse über z. B. Geräte, ZfP-Verfahrensbeschreibungen, Materialien und Produkte benötigen könnte, die für den Arbeitgeber spezifisch sind.
Wenn es eine gesetzliche Forderung Anforderung oder aber eine durch Regelwerke gibt, dann muss die Autorisierung zur Ausführung in schriftlicher Form durch den Arbeitgeber in Einklang mit einer Qualitätsverfahrensbeschreibung erteilt werden, die das für den Arbeitgeber erforderliche Job-spezifische TrainingTätigkeitsspezifische Ausbildung und die Prüfung beschreibt, die dazu dienen, zu verifizieren (...)
Essais non destructifs - Qualification et certification du personnel END - Principes généraux (ISO 9712:2012)
L'ISO 9712:2012 spécifie des exigences pour les principes de qualification et de certification du personnel chargé d'effectuer des essais non destructifs (END) industriels.

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 9712 was prepared by Technical Committee ISO/TC 135, Non-destructive testing, Subcommittee SC 7,
Personnel qualification.
This fourth edition cancels and replaces the third edition (ISO 9712:2005), which has been technically revised.
Changes from the third edition include:
— clarification of responsibilities for the certification body, the qualification body, and the examination centre;
— redrafting of the clause “training” for clarification and change in the number of required hours;
— redrafting of the clause “experience” for clarification;
— introduction of “digital certificates”;
— other minor technical and editorial changes.

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 International Standard. When latitude is provided in
the criteria within this International Standard, 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 International Standard as a reference document.

INTERNATIONAL STANDARD ISO 9712:2012(E)
Non-destructive testing — Qualification and certification of
NDT personnel
1 Scope
This International Standard specifies requirements for principles for the qualification and certification of
personnel who perform industrial non-destructive testing (NDT).
NOTE 1 The term “industrial” implies the exclusion of applications in the field of medicine.
The system specified in this International Standard can also apply to other NDT methods or to new techniques
within an established NDT method, provided a comprehensive scheme of certification exists and the method
or technique is covered by International, regional or national standards or the new NDT method or technique
has been demonstrated to be effective to the satisfaction of the certification body.
[5]
NOTE 2 CEN/TR 14748 can be used as guidance.
The certification covers proficiency in one or more of the following methods:
a) acoustic emission testing;
b) eddy current testing;
c) infrared 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).
NOTE 3 This International Standard 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 International Standard can be referred to in such arrangements.
NOTE 4 Wherever gender specific words such as “his”, “her”, “he” or “she” appear in this International Standard, the
other gender is also applicable.

SIST EN ISO 9712 : 2012
Predgovor k mednarodnemu standardu
ISO (Mednarodna organizacija za standardizacijo) je svetovna zveza nacionalnih organov za
standarde (članov ISO). Mednarodne standarde navadno pripravljajo tehnični odbori ISO. Vsak član,
ki želi delovati na določenem področju, za katero je bil ustanovljen tehnični odbor, ima pravico biti
zastopan v tem odboru. Pri delu sodelujejo tudi mednarodne vladne in nevladne organizacije,
povezane z ISO. V vseh zadevah, ki so povezane s standardizacijo na področju elektrotehnike,
ISO tesno sodeluje z Mednarodno elektrotehniško komisijo (IEC).
Osnutki mednarodnih standardov so pripravljeni v skladu s pravili iz 2. dela direktiv ISO/IEC.
Glavna naloga tehničnih odborov je pripravljanje mednarodnih standardov. Osnutki mednarodnih
standardov, ki jih sprejmejo tehnični odbori, se pošljejo vsem članom v glasovanje. Za objavo
mednarodnega standarda je treba pridobiti soglasje najmanj 75 odstotkov članov, ki se udeležijo
glasovanja.
Opozoriti je treba na možnost, da so lahko nekateri elementi tega dokumenta predmet patentnih
pravic. ISO ni odgovoren za identifikacijo nekaterih ali vseh takih patentnih pravic.
Standard ISO 9712 je pripravil tehnični odbor ISO/TC 135 Neporušitvene preiskave, pododbor SC 7
Kvalificiranje osebja.
Četrta izdaja razveljavlja in nadomešča tretjo izdajo (ISO 9712:2005), ki je bila strokovno revidirana.
Spremembe glede na tretjo izdajo vključujejo:
– pojasnitev odgovornosti certifikacijskega organa, kvalifikacijskega organa in izpitnega centra;
– preoblikovanje točke »usposabljanje« zaradi pojasnitve in spremembe števila zahtevanih ur;
– preoblikovanje točke »izkušnje« zaradi pojasnitve;
– uvedbo »digitalnih certifikatov«;
– druge manjše tehnične in uredniške spremembe.

SIST EN ISO 9712 : 2012
Uvod k mednarodnemu standardu
Ker je učinkovitost katere koli uporabe neporušitvenih preiskav (NDT) odvisna od sposobnosti osebe,
ki preiskavo izvaja ali je zanjo odgovorna, je bil razvit postopek, ki omogoča ocenjevanje in
dokumentiranje kompetentnosti osebja, ki mora imeti ustrezno teoretično in praktično znanje o
neporušitvenih preiskavah, ki jih izvaja, določa, nadzoruje, spremlja ali ocenjuje. Dodatna pobuda
izvira iz svetovne primerljivosti širokega razpona industrijskih uporab, za katere so potrebni skupni
pristopi k neporušitvenim preiskavam.
Kadar je v standardih za proizvode, v predpisih, pravilnikih ali specifikacijah zahtevano certificiranje
osebja za neporušitvene preiskave, je treba osebje certificirati v skladu s tem mednarodnim
standardom. Kadar merila v okviru tega mednarodnega standarda niso strogo določena, končno
odločitev pri določanju posebnih zahtev sprejme certifikacijski organ.
Kadar zakonodaja, standard ali nalog za certificiranje osebja za neporušitvene preiskave ne vsebujejo
zahtev, se morajo delodajalci zgoraj omenjenega osebja odločiti, na kakšen način bodo preverili
kompetentnost osebja za opravljanje delovnih nalog. Tako lahko zaposlijo strokovnjake, ki so že
certificirani, ali pa s svojim strokovnim znanjem preverijo ustrezno usposobljenost osebja. V zadnjem
primeru naj bi preudarni delodajalci kot referenčni dokument uporabili ta mednarodni standard.

SIST EN ISO 9712 : 2012
Neporušitvene preiskave – Kvalificiranje in certificiranje osebja za neporušitvene
preiskave
1 Področje uporabe
Ta mednarodni standard določa zahteve za načela kvalificiranja in certificiranja osebja, ki izvaja
industrijske neporušitvene preiskave (NDT).
OPOMBA 1: Izraz »industrijski« pomeni, da je izključena uporaba na medicinskem področju.
Sistem iz tega mednarodnega standarda se lahko uporablja tudi za druge metode neporušitvenih
preiskav ali za nove tehnike v okviru uveljavljene metode neporušitvenih preiskav po shemi
certificiranja in če je metoda ali tehnika opisana v mednarodnih, regionalnih ali nacionalnih standardih
ali če se certifikacijskemu organu zadovoljivo dokaže učinkovitost novih metod ali tehnik
neporušitvenih preiskav.
[5]
OPOMBA 2: Standard CEN/TR 14748 je mogoče uporabiti kot navodilo.
Certificiranje vključuje poznavanje uporabe ene ali več naslednjih metod:
a) preiskava z akustično emisijo;
b) preiskava z vrtinčnimi tokovi;
c) infrardeča termografska preiskava;
d) preiskava tesnosti (izključeni so hidravlični tlačni preskusi);
e) magnetna preiskava;
f) penetrantska preiskava;
g) radiografska preiskava;
h) preiskava z uporovnim merilnim lističem;
i) ultrazvočna preiskava;
j) vizualna preiskava (izključene so vizualne preiskave brez pripomočkov in vizualne preiskave,
izvedene med uporabo drugih metod neporušitvenih preiskav).
OPOMBA 3: Ta mednarodni standard določa zahteve za sheme za ugotavljanje skladnosti, ki ga izvajajo tretje osebe. Te
zahteve se ne uporabljajo neposredno za ugotavljanje skladnosti, ki ga izvajajo druge ali prve osebe, mogoče
pa se je v takih dogovorih sklicevati na ustrezne dele tega mednarodnega standarda.
OPOMBA 4: Kadar se v tem mednarodnem standardu uporabljajo besede, značilne za en spol, kot so »njegov«, »njen«,
»on« ali »ona«, je zajet tudi drugi spol.

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 9712 was prepared by Technical Committee ISO/TC 135, Non-destructive testing, Subcommittee SC 7,
and by Technical Committee CEN/TC 138, Non-destructive testing in collaboration.
This fourth edition cancels and replaces the thirs edition (ISO 9712:2005), which has been technically revised.
The main changes are :
separation of the method "Magnetic testing" into two sub-methods: Magnetic Particle testing and Flux leakage testing
clarification of responsibilities for Certification body, Qualification body and Examination Centre
rewrite of the clause "Training" for clarification and change in the number of required hours
rewrite of the clause "Experience" for clarification
introduction of "Digital Certificates"
for level 3 recertification, deletion of the requirement for the demonstration of practical skill
other minor technical and editorial changes

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 was 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 world-wide 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 International Standard. When latitude is provided in
the criteria within this International standard, 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 the employer of such personnel to decide how to assure himself that they are competent to do the work
assignments. So he may employ people who are already certified, or he may apply his own expertise so as to
assure himself that his employee has the necessary competence. In this last case a prudent employer would
no doubt use this standard as a reference document.

ISO/DIS 9712
Non-destructive testing — Qualification and certification of NDT
personnel — General principles
1 Scope
This International Standard establishes principles for the qualification and certification of personnel who
perform industrial non-destructive testing (NDT).
NOTE 1 The term ‘industrial’ implies the exclusion of applications in the field of medicine.
The system described in this International Standard can also apply to other NDT methods, or to new
techniques within an established NDT method, provided a comprehensive scheme of certification exists and
the method or technique is covered by International, European, regional or national standards,
The certification covers proficiency in one or more of the following methods :
a) acoustic emission testing;
b) eddy current testing;
c) infrared thermography testing;
d) leak testing (hydraulic pressure tests excluded);
e) magnetic testing (magnetic particle testing and flux leakage testing) ;
f) penetrant testing;
g) radiographic testing;
h) strain 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).
Certification to this International Standard provides an attestation of general competence of the NDT operator.
It does not represent an authorization to operate, since this remains the responsibility of the employer, and the
certified employee may require additional specialized knowledge of parameters such as equipment, NDT
procedures, materials and products specific for the employer.
Where required by regulatory requirements and codes, the authorization to operate shall be given in writing by
the employer in accordance with a quality procedure that defines any employer required job -specific training
and examinations designed to verify the certificate holder's knowledge of relevant industry code(s),
standard(s), NDT procedures, equipment, and acceptance criteria for the tested products.
NOTE 2 This standard 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 standard
can be referred to in such arrangements.
