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 18436-6 was prepared by Technical Committee ISO/TC 108, Mechanical vibration, shock and condition
monitoring, Subcommittee SC 5, Condition monitoring and diagnostics of machines.
ISO 18436 consists of the following parts, under the general title Condition monitoring and diagnostics of
machines — Requirements for qualification and assessment of personnel:
⎯ Part 1: Requirements for certifying bodies and the certification process
⎯ Part 2: Vibration condition monitoring and diagnostics
⎯ Part 3: Requirements for training bodies and the training process
⎯ Part 4: Field lubricant analysis

Introduction
The use of acoustic emission technology in condition monitoring is one of the key activities in predictive
maintenance programmes for most industries. Other non-intrusive technologies including infrared
thermography, vibration analysis, lubricant analysis, wear debris analysis and motor current analysis are used
as complementary condition analysis tools. Those in the manufacturing industry who have diligently and
consistently applied these technologies have experienced a return on investment far exceeding their
expectations. However, the effectiveness of these programmes depends on the capabilities of individuals who
perform the measurements and analyse the data.
A programme, administered by an assessment body, has been developed to train and assess the competence
of personnel whose duties require the appropriate theoretical and practical knowledge of machinery condition
monitoring and diagnostics.
This part of ISO 18436 defines the requirements against which personnel in the non-intrusive machinery
condition monitoring and diagnostics technologies associated with acoustic emission for machinery condition
monitoring are to be qualified and the methods of assessing such personnel.

Acoustic emission
1 Scope
This part of ISO 18436 specifies the requirements for qualification and assessment of personnel who perform
machinery condition monitoring and diagnostics using acoustic emission.
A certificate or declaration of conformity to this part of ISO 18436 will provide recognition of the qualifications
and competence of individuals to perform acoustic emission measurements and analysis for machinery
condition monitoring using acoustic emission equipment. This procedure may not apply to specialized
equipment or other specific situations.
This part of ISO 18436 specifies a three-category classification programme that is based on the technical
areas delineated herein.

4 Classification of personnel (acoustic emission)
4.1 General
Individuals assessed as conforming to the requirements of this part of ISO 18436 shall be classified in one of
three categories, depending upon their qualifications. They shall have demonstrated the necessary skills in
acoustic emission condition monitoring for their category as indicated in Annex A.
Personnel classified as Category II need to have all the knowledge and skills expected of personnel classified
as Category I, while personnel classified as Category III need to have all the knowledge and skills expected of
personnel classified as Category II.
4.2 Category I
Individuals classified as Category I are qualified to perform acoustic emission measurements according to
established and recognized procedures. Personnel classified as Category I shall be able to:
a) apply a specified acoustic emission measurement procedure;
b) set up and verify operation of equipment for basic acoustic emission data collection;
c) verify the integrity of collected data and prevent or control poor data;
d) perform basic acoustic emission analysis;
