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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 108, Mechanical vibration, shock and condition
monitoring, Subcommittee SC 5, Condition monitoring and diagnostics of machines.
This third edition cancels and replaces the second edition (ISO 18436-3:2012), of which it constitutes a
minor revision.
The main changes are as follows:
— updated terminology to harmonize the document with current industry practice (such as, removing the
use of term ‘qualification’ and ‘assessment’ where practicable);
— the part title was aligned with the other parts of the ISO 18436 series.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Introduction
Condition monitoring and diagnostics of machines are integral parts of an effective maintenance programme.
Non-intrusive technologies used in condition monitoring and fault diagnosis include vibration, infrared
thermography, oil and wear debris analysis, acoustic and ultrasonic analysis, and electrical signature
analysis. In many instances these technologies act as complementary condition monitoring tools. The skills
and expertise of the practitioners performing the measurements and analysing the data are critical to the
effective application of these technologies.
This document defines the requirements for bodies operating training programmes in the non-intrusive
machine condition monitoring, diagnostic, and correction technologies. General requirements for training
body personnel are contained in this document. Specific requirements for personnel in condition monitoring
and diagnostics are covered in other parts of the ISO 18436 series.
