Live working - Telescopic sticks and telescopic measuring sticks

Covers telescopic sticks and telescopic measuring sticks to be used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and 1 500 V and above for d.c. The telescopic sticks are designed to accept attachments that meet appropriate live working standards and, together with these attachments, may be used to perform mechanical work on live parts at a distance. Telescopic sticks are also designed to accept diagnostic devices that meet appropriate live working standards and are used to make the diagnostic devices reach parts of an installation to be tested. Telescopic measuring sticks, or tele-scopic sticks equipped with graduations, are used to measure distances to or between live parts. The tools (telescopic sticks and telescopic measuring sticks) covered by this standard are for use under dry conditions but could also be used under very humid conditions, using appropriate working procedures.

TELESCOPIC STICKS AND
TELESCOPIC MEASURING STICKS
FOREWORD

1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.

3) The documents produced have the form of recommendations for international use and are published in the form

of standards, technical specifications, technical reports or guides and they are accepted by the National

Committees in that sense.

4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

indicated in the latter.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject

of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62193 has been prepared by IEC technical committee 78: Live

working.
The text of this standard is based on the following documents:
FDIS Report on voting
78/513/FDIS 78/523/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 2010.

At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

LIVE WORKING –
TELESCOPIC STICKS AND
TELESCOPIC MEASURING STICKS
1 Scope

This International Standard covers telescopic sticks and telescopic measuring sticks to be

used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and

1 500 V and above for d.c.

The telescopic sticks are designed to accept attachments that meet appropriate live working

standards and, together with these attachments, may be used to perform mechanical work

on live parts at a distance. Telescopic sticks are also designed to accept diagnostic devices

that meet appropriate live working standards and are used to make the diagnostic

devices reach parts of an installation to be tested. Telescopic measuring sticks, or tele-

scopic sticks equipped with graduations, are used to measure distances to or between

live parts.

NOTE Under certain circumstances, the telescopic sticks covered by this standard can be used for installing

portable earthing or earthing and short-circuiting equipment if the mechanical stresses during use are lower than

the rated values.

The tools (telescopic sticks and telescopic measuring sticks) covered by this standard are for

use under dry conditions but could also be used under very humid conditions, using

appropriate working procedures.

Telescopic hook sticks are not covered by this standard. Telescopic bonding sticks and any

other speciality telescopic sticks designed at the request of users are not covered by this

standard.
