INTERNATIONAL ELECTROTECHNICAL COMMISSION
SADDLES, POLE CLAMPS (STICK CLAMPS) AND
ACCESSORIES FOR LIVE WORKING
FOREWORD
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
1)
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation 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.
The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
2)
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
They have the form of recommendations for international use published in the form of standards, technical
3)
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.
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
5)
equipment declared to be in conformity with one of its standards.
International Standard IEC 1236 has been prepared by IEC technical committee 78: Tools
for live working.
The text of this standard is based on the following documents:

INTRODUCTION
This International Standard covers general matters. It should not be considered complete
in itself and it leaves to each customer the task of adding his own complementary
requirements. These will cover, for example, required mechanical performance and
conditions of interchangeability with equipment already in service.

SADDLES, POLE CLAMPS (STICK CLAMPS) AND
ACCESSORIES FOR LIVE WORKING
Section 1: General
1.1 Scope
This International Standard is applicable to saddles and pole clamps (stick clamps) used
for live working, and to their accessories.
It specifies:
the dimensional and mechanical characteristics to be given by the manufacturer for
-
each tool;
the corresponding mechanical tests;
-
- the other points to be checked (visual, functional, marking, etc.).
1.2 Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this International Standard. At the time of publication, the
editions indicated were valid. All normative documents are subject to revision, and parties
to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated
below. Members of IEC and ISO maintain registers of currently valid International
Standards.

1.3.1.3 sampling test: A test on a number of devices taken at random from a batch.
[IEV 151-04-17]
1.3.1.4 acceptance test: A contractual test to prove to the customer that the device
meets certain conditions of its specification. [IEV 151-04-20]
rated value: A quantity value assigned, generally by a manufacturer, for a
1.3.1.5
specified operating condition of a component, device or equipment. [IEV 151-04-03]
1.3.1.6 minor defect: A minor defect is a defect that is not likely to reduce materially
the usability of the unit of product for its intended purpose, or is a departure from
established standards having little bearing on the effective use or operation of the unit
(see 2.1.3, IEC 410).
1.3.1.7 major defect: A major defect is a defect, other than critical, that is likely to
result in failure, or to reduce materially the usability of the unit of product for its intended
purpose (see 2.1.2, IEC 410).
1.3.1.8 critical defect: A critical defect is a defect that judgment and experience
indicate is likely to result in hazardous or unsafe conditions for individuals using,
maintaining or depending upon the product; or a defect that judgment and experience
indicate is likely to prevent performance of the function of a major end item (see 2.1.1,
IEC 410).
1.3.2 Definition of special terms
1.3.2.1 type of tool: Tools which have the same design and equal dimensions.
1.3.2.2 family of tools: Tools which have the same function (utilization, use, etc.).
1.3.2.3 MICDT (minor defect control test): Application of a specified force or torque
(specified in the standard) to a tool to verify whether any minor defect has occurred.
1.3.2.4 MADCT (major defect control test): Application of a specified force or torque
(specified in the standard) to a tool to verify whether any major or critical defect has
occurred.
1.3.2.5 TN : Rated torque given by the manufacturer for a tool or a part of a tool for
testing purposes.
FTN : Rated tensile force given by the manufacturer for a tool or a part of a tool
1.3.2.6
for testing purposes.
Rated bending force given by the manufacturer for a tool or a part of a tool
1.3.2.7 FBN :
for testing purposes.
1.3.2.8 FGN : Rated slippage force given by the manufacturer for a tool for testing
purposes.
