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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 third edition cancels and replaces the first edition which was issued as a technical report
in 1994 with its Corrigendum 1 (2000), and the second edition, withdrawn, which was issued
as a standard in 2003. It includes the following significant technical changes from the
previous edition:
– change of the purpose of the document from a support to standard writers to a standard
for assessing the conformity by testing of products having completed the production
phase;
– clarification of the definitions of critical, major and minor defects;
– specification of ISO 2859 for the manufacturers to define the appropriate sampling plans;
– review of the acceptance quality limit (AQL) to specify lower limits.

The text of this standard is based on the following documents:
FDIS Report on voting
78/705/FDIS 78/713/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
This publication provides elements for product conformity assessment.
This standard is specified in each IEC product standard for live working for the purpose of
assessing that products having completed the production phase meet the requirements of the
relevant product standard.
It can be used as a basis for production certification.
TC 78 prepares product standards which include requirements and normative tests for design
input (type tests).
Product conformity assessment elements related to the production phase (among them is the
procedure to associate routine and sampling tests to the classification of defects) are included
in the present standard.
This publication does not cover conformity of commercial shipments. Shipments can contain
products coming from several production batches. Batches are here understood as related to
production.
This publication is not a quality management systems standard.

LIVE WORKING –
CONFORMITY ASSESSMENT APPLICABLE
TO TOOLS, DEVICES AND EQUIPMENT

1 Scope
This International Standard provides elements for product conformity assessment. Critical
defects on tools, devices and equipment for live working are not acceptable. Major defects on
tools, devices and equipment for live working are likely to result in failure or in a significant
reduction of functionality, while minor defects do not reduce significantly the functionality.
This standard defines assessment methods for products having completed production phase
to assure that they conform to the requirements of the corresponding product standard. It is to
be used in conjunction with live working corresponding product standards.
The following elements are not covered by the present document, but are included in each
product standard:
– type tests;
– provisions and description for sampling and routine tests;
– the identification and classification of the corresponding defects resulting from a risk
analysis.
