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 11484 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 19, Technical delivery
conditions for steel tubes for pressure purposes.
This second edition cancels and replaces the first edition (ISO 11484:1994), which has been technically
revised.

ISO 11484:2009(E)
Introduction
This International Standard concerns the qualification of personnel engaged in non-destructive testing (NDT)
of steel products.
It has been recognized that, within the steel industry worldwide, there is a predominance of semi-
automatic/automatic NDT equipment in use by NDT personnel to establish product integrity, as opposed to
principally manual methods adopted in other industrial sectors. As a result, this International Standard
permits employer qualification, subject to certain restrictions.
In the preparation of this International Standard, the requirements of ISO 9712 have been taken into
account or adopted where they apply. However, it should be noted that the primary job-specific nature of
the NDT tasks performed by NDT personnel on steel products is clearly outside the scope of ISO 9712
(see 3.13 of ISO 9712:2005).
Thus, in the context of this International Standard, the requirements of ISO 9712 should not be taken as
basic or additional minimum requirements, but this does not preclude the right of any individual to apply for
and obtain qualification/certification in conformance with ISO 9712, as may be appropriate in another sector.
It is recognized that this International Standard may be applied to steel products and other specific product
areas, as appropriate.

the employer for a specific product and a specific method.
1.3 This International Standard is intended to apply to NDT personnel performing predominantly automated
inspection of steel products, using any of the following NDT methods:
a) eddy current testing (ET);
b) flux leakage testing (FT);
c) leak testing (LT);
d) liquid penetrant testing (PT);
e) magnetic particle testing (MT);
f) radiographic testing (RT);
g) ultrasonic testing (UT);
h) visual inspection testing (VT).

4 General principles
4.1 Under the requirements of this International Standard, the employer has sole responsibility for providing
a declaration of competence that a person in its employ performing NDT tasks has a prerequisite qualification
and has successfully passed qualification examinations, conducted under the auspices of the employer, in
one or more of the NDT methods covered by this International Standard, in respect of one of the two levels of
competence (Level 1 or Level 2).
As an alternative to the use of qualified Levels 1 and/or 2 personnel in the regular employ of the employer to
carry out the required NDT operations, the employer is permitted to engage, on a contract basis, certified
Level 1 or Level 2 personnel in accordance with ISO 9712 or equivalent.
In addition, a certified Level 3 individual, either in the regular employ of, or engaged by, the employer, has the
responsibility for administering Level 1 and Level 2 personnel qualification examinations.
4.2 The prerequisite qualification requirements in terms of visual acuity, basic education, training and
experience shall be fulfilled by each candidate for eligibility for the qualification examinations. These
prerequisite requirements shall be verified by the employer and endorsed on the qualification record.
4.3 The qualification examination for Level 1 and Level 2 personnel shall consist of three parts: a written
general part, a written specific examination and a practical examination.
4.4 The general, specific and practical examinations of the qualification examination shall be conducted, at
the employer's discretion, either by the employer's qualifying body or by the employer’s authorized/approved
external qualifying body.
4.5 The employer's qualifying body shall be constituted by individuals independent of the production
departments. These individuals form an independent examining body, including at least one certified Level 3
individual not necessarily in the employ of the employer but nominated by the employer's qualifying body as
an examiner for Level 1 and Level 2 personnel.
Such a certified Level 3 individual shall be responsible for administering Level 1 and Level 2 personnel
qualification examinations and its proper conduct.

---------------------- Page: 8 ----------------------
ISO 11484:2009(E)
Employer authorized/approved external qualifying bodies shall also meet these basic requirements.
4.6 The qualification examination results shall be checked/verified by the qualifying body to ensure that the
pass-mark requirements have been fulfilled and the employer’s qualifying body, on the qualifying body’s
recommendation, shall issue a qualification record in respect of the individual, with regard to the NDT method
and level of competence (Level 1 or Level 2). The issue of the qualification record provides the individual with
the authorization to carry out specified NDT tasks within the employer's production facilities (i.e. authorization
to operate).
This qualification record is thus only valid while the individual is in the employ of, or engaged by, the employer
issuing the qualification record.
4.7 The activities for qualification up to the issue of a qualification record shall be specified in a written
procedure.
5 Levels of qualification
5.1 General
NDT personnel qualified in accordance with this International Standard shall be classified in one of two levels
of competence (Level 1 or Level 2) with respect to specific NDT tasks to be performed.
Both levels of competence are defined in terms of NDT task content, degree of responsibility, etc. in
accordance with 5.2 and 5.3.
5.2 NDT Level 1
An individual qualified to NDT Level 1 shall have demonstrated competence to carry out NDT according to
NDT instruction and under the supervision of qualified Level 2 or certified Level 3 personnel. Within the scope
of the competence defined on the qualification, Level 1 personnel may be authorized by the employer to
⎯ set up the NDT equipment,
⎯ carry out the tests,
⎯ record and classify the results of the tests in terms of written criteria, and
⎯ report the results.
He/she shall not be responsible for the choice of the test method or technique to be used, or for the
assessment of test results.
5.3 NDT Level 2
An individual qualified to NDT Level 2 shall have demonstrated competence to perform NDT according to
established procedures in the test method in which he/she is qualified. Within the scope of the competence
defined for the qualification, Level 2 personnel may be authorized by the employer to
⎯ select the NDT technique for the test method to be used,
⎯ define the limitations of application of the testing method/technique(s),
⎯ interpret NDT codes, standards, specifications and procedures into practical testing instructions adapted
to the actual working conditions,
⎯ set up and verify equipment settings,

⎯ perform and supervise the tests,
⎯ interpret and evaluate results according to applicable codes, standards or specifications,
⎯ prepare written NDT instructions,

The qualifying body, through the authorized certified Level 3 individual, shall qualify NDT Level 1 and Level 2
candidates in accordance with Clauses 7 and 8. Once the candidate has be
