LIVE WORKING –
SADDLES, STICK CLAMPS AND THEIR ACCESSORIES


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 61236 has been prepared by IEC technical committee 78: Live
working.
This second edition cancels and replaces the first edition published in 1993. It constitutes a
technical revision.
It includes the following significant technical changes from the previous edition:
– clarification of the requirements and of the test provisions;
– addition of a test for the durability of marking;
– application of conformity assessment for products having completed the production phase,
according to IEC 61318:2007 (Ed. 3).

INTRODUCTION
The requirements provided in this standard are essential requirements. Each user of this
standard may supplement it with their own requirements. These will cover, for example,
required mechanical performance and conditions of interchangeability with equipment
already in service. In such cases, caution should be taken to maintain or improve the
performance of the products.
This International Standard has been prepared in accordance with the requirements of
IEC 61477.
The products covered by this standard may have an impact on the environment during some
or all stages of its life cycle. These impacts can range from slight to significant, be of short-
term or long-term, and occur at the global, regional or local level.
Except for a disposal statement in the instructions for use, this standard does not include
requirements and test provisions for the manufacturers of the product, or recommendations to
the users of the product for environmental improvement. However, all parties involved in the
product’s design, manufacture, packaging, distribution, use, maintenance, repair, reuse,
recovery and disposal are encouraged to take account of environmental considerations.

– 10 – 61236 © IEC:2010
– symbol IEC 60417-5216:2002-10 – Suitable for live working; double triangle (Annex A);
NOTE The exact ratio of the height of the figure to the base of the triangle is 1,43. For the purpose of
convenience, this ratio can be between the values of 1,4 and 1,5.
– number of the relevant IEC standard immediately adjacent to the symbol (IEC 61236).
Information or characteristics not required at the work site, such as year of publication of the
standard, shall be provided by other means (bar codes, microchips, etc.) or shall be provided
on the packaging.
4.6 Instructions for use
Each device shall come with the manufacturer’s instructions for use and care. These
instructions shall be prepared in accordance with the general provisions given in IEC 61477.
These instructions shall include at least
– maximum mechanical rating;
– recommended application(s);
– recommendations for cleaning, storage, transportation, periodic testing, refinishing and
disposal.
5 Tests
5.1 General
This standard provides testing provisions to demonstrate compliance of the product with the
requirements of Clause 4. These testing provisions are primarily intended to be used as type
tests for validation of the design input. Where relevant, alternative means (calculation,
examination, tests, etc.), are specified within the test subclauses for the purpose of saddles,
stick clamps and their accessories having completed the production phase.
To show compliance with this standard, the manufacturer shall prove that the type tests have
been carried out successfully on at least three devices for each type.
However, when the differences between several types of device are limited in number, tests
that are unaffected by the differing characteristics of the devices can be carried out on a
single type of device, and the results can be used for the other device types.
The different type tests, and the order in which these tests are performed are given in
Annex B.
The tests in Tables B.1, B.2, B.3 and B.4 of Annex B shall be performed, following the
specified order.
NOTE In Tables B.1, B.2, B.3 and B.4 the numbers within parentheses provide reference to the Subclause where
the relevant test is explained. For some families of devices, columns are divided in sub-columns equal to the
number of mechanical tests to be applied to these devices (these may be destructive). These sub-columns also
show the sequence of tests to be applied (for an example see Table B.5).
Any device failing to pass any one of the tests mentioned in Tables B.1, B.2, B.3 and B.4 of
Annex B shall result in the design being rejected.
5.2 Visual and functional inspection
Each device shall be visually inspected to detect manufacturing defaults and to check proper
functioning.

---------------------- Page: 16 ----------------------

SIST EN 61236:2011
61236 © IEC:2010 – 11 –
The test shall be considered as passed if each device shows compliance with the
requirements included in 4.3, 4.4, 4.5 and 4.6 where applicable.
5.3 Dimensional check
Each device shall be measured to ensure that its dimensions match the manufacturer’s rated
dimensions.
5.4 Durability of marking
The durability of the marking shall be verified by thoroughly cleaning the marking for at least
1 min with a piece of lint-free cloth dampened with water and then rubbing it vigorously for a
further minimum of 1 min with a piece of lint-free cloth dampened with isopropanol (CH -
3
CH(OH)-CH ).

NOTE 1 It is the employer’s duty to ensure that any relevant legislation and any specific safety instructions
regarding the use of isopropanol are fully observed.
The test shall be considered as passed if the marking remains legible and the letters do not
smear.
