DEGREES OF PROTECTION PROVIDED BY ENCLOSURES
FOR ELECTRICAL EQUIPMENT AGAINST EXTERNAL
MECHANICAL IMPACTS (IK CODE)
AMENDMENT 1
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 document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to IEC 62262:2002 has been prepared by IEC technical committee 70: Degrees
of protection provided by enclosures.
The text of this Amendment is based on the following documents:
Draft Report on voting
70/157/FDIS 70/158/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this Amendment is English.

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/publications/.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
___________
1 Scope
Replace the existing text with the following new text:
This document refers to the classification of the degrees of protection provided by enclosures
against external mechanical impacts when the rated voltage of the protected equipment is not
greater than 72,5 kV.
The object of this document is to give
a) the definitions for the degrees of protection provided by enclosures of electrical equipment
as regards protection of the equipment inside the enclosure against harmful effects of
mechanical impacts;
b) the designations for the degrees of protection;
c) the requirements for each designation;
d) the tests to be performed to verify that the enclosure meets the requirements of this
document.
It will remain the responsibility of individual technical committees to decide on the extent and
manner in which the classification is used in their standards and to define the "enclosure" as it
applies to their equipment and to ensure that for a given classification, the tests do not differ
from those specified in this document. If necessary, complementary requirements can be
included in the relevant product standard.
For a particular type of equipment, a product committee can specify different requirements
provided that at least the same level of safety is ensured.
This document deals only with enclosures that are in all other respects suitable for their
intended use as specified in the relevant product standard and which, from the point of view of
materials and workmanship, ensure that the claimed degrees of protection are maintained under
the normal conditions of use.
