Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)

form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC

participate in the development of International Standards through technical committees established by the

respective organization to deal with particular fields of technical activity. ISO and IEC technical committees

collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in

liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have

established a joint technical committee, ISO/IEC JTC 1.

In addition to developing International Standards, ISO/IEC JTC 1 also develops International Standardized Profiles.

An International Standardized Profile is an internationally agreed, harmonized document which identifies a

standard or group of standards, together with options and parameters, necessary to accomplish a function or a set

of functions. Draft International Standardized Profiles adopted by the joint technical committee are circulated to

national bodies for voting. Publication as an International Standardized Profile requires approval by at least 75 % of

the national 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 and IEC shall not be held responsible for identifying any or all such patent rights.

International Standard ISO/CD 11774 was prepared by Technical Committee ISO/TC 135, Non-destructive testing

Subcommittee SC 7, Personnel qualification, WG 7 Performance based qualification.

ISO/DIS 11774
Introduction

Performance demonstration establishes the ability of a specific examination system (i.e. equipment, procedures

and personnel) to achieve a desirable level of performance. The pre-established criteria for acceptable

performance is based on an industry obtaining desired test results on flawed and non-flawed qualification

specimens including an established acceptable false call rate using qualified procedures and equipment.

NOTE Wherever gender specific words such as "his", "her", "he" or "she" appear in this International Standard

the other gender is also applicable.

Non-destructive testing – Performance based qualification
1 Scope

1.1 This standard provides a method for qualification of non-destructive testing personnel for specific non-

destructive tests conducted in accordance with documented procedures established within a performance based

qualification program.

1.2 Implementation of this standard will require cooperation between applicable Industry Sector Committees

(ISCs) and qualification bodies to assure that specific performance expectations are addressed.

1.3 The qualification methodology described in this standard is based upon the candidate’s ability to demonstrate

capability in detecting and sizing critical flaws equivalent to those to be detected and sized in the performance

based qualification program as established by the ISC.

1.4 Second party (employer based) qualification and approval (for example in accordance with ANSI/ASNT CP-

189) or qualification and third party certification (for example, in accordance with ISO 9712 or EN 473), followed by

on-the-job training may not provide the required degree of confidence for safety critical inspections, and this

standard provides criteria to assist in preparing an individual for performance based qualification examinations.

1.5 Qualification to this international standard is limited to the specific applications, using the specific documented

procedure in the performance based qualification program. Levels of qualification are not applicable.

NDT procedure

written description of all essential parameters and precautions to be applied when non-destructively testing

products in accordance with standard(s), code(s) or specification(s)

methodology for establishing the ability of a specific qualification system (for equipment, procedures and

personnel) to achieve a required level of performance

equipment and/or NDT procedures according to the requirements of this International Standard

3.12

5 Prerequisites for performance base qualification examinations
5.1 Basic method qualification

are capable of performing non-destructive tests using the qualified NDT procedure. The experience may be

obtained with the use of virtual training systems, or by examining representative specimens with relevant and non-
