FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61318 has been prepared by IEC technical committee 78: Live
working.
This fourth edition cancels and replaces the third edition published in 2007. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) change of the purpose of the document from a prescriptive testing standard to a standard
assisting the project team in the conformance to respective product standard;
b) introduction of conformance test, record of process, quality control documentation,
adapted to the standard product;
c) change of prescribed sampling procedure to adapted sampling tests to the product
standard;
– 4 – IEC 61318:2021 © IEC 2021
d) suppression of the term “conformity assessment”;
e) Introduction of the term “verification method” replacing “conformity assessment
application”.
The text of this International Standard is based on the following documents:
FDIS Report on voting
78/1339/FDIS 78/1353/RVD
Full information on the voting for its approval can be found in the report on voting indicated in

INTRODUCTION
This document is applied by each IEC Live Working product standard for the purpose of
assessing whether or not each product meets the requirements of the relevant product
standard.

METHODS FOR ASSESSMENT OF DEFECTS AND
VERIFICATION OF PERFORMANCE APPLICABLE
TO TOOLS, DEVICES AND EQUIPMENT

1 Scope
This document defines methods to assess defects and to verify that products after the
manufacturer process meet the requirements of the corresponding product standard.
The principles of assessment of defects for live working products are detailed in this
document to assist product standard developers in prescribing the best means to achieve
suitable quality of every finished tool, device and piece of equipment.
The following elements are not covered by the present document, but are included in each
product standard:
– type tests;
– provisions and description for routine, sampling and acceptance tests;
– identification and classification of defects;
– risk analysis.
This document does not cover conformity assessment of commercial shipments or
certifications.
2 Normative references
There are no normative referenced documents.
3 Terms and definitions
