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.

INTRODUCTION
This standard describes a system for classifying the degrees of protection provided by the
enclosures of electrical equipment. Whilst this system is suitable for use with most types of
electrical equipment, it should not be assumed that all the listed degrees of protection are
applicable to a particular type of equipment. The manufacturer of the equipment should be
consulted to determine the degrees of protection available and the parts of equipment to
which the stated degree of protection applies.
The adoption of this classification system, wherever possible, Will promote uniformity in
methods of describing the protection provided by the enclosure and in the tests to prove the
various degrees of protection. It should also reduce the number of types of test devices
necessary to test a wide range. of products.
This second edition of IEC 60529 takes account of experiences with the first edition, and
clarifies the requirements. It provides for an optional extension of the IP Code by an additional
letter A, B, C, or D if the actual protection of persons against access to hazardous parts is
higher than that indicated by the first characteristic numeral.
In general, enclosures with an IP coding to the first edition would be eligible for the same
code according to this edition.

DEGREES OF PROTECTION PROVIDED
BY ENCLOSURES (IP Code)
1 Scope and object
This standard applies to the classification of degrees of protection provided by enclosures for
electrical equipment with a rated voltage not exceeding 72,5 kV.
2 Object
The object of this standard is to give:
a) Definitions for degrees of protection provided by enclosures of electrical equipment as
regards:
1) protection of persons against access to hazardous parts inside the enclosure;
2) protection of the equipment inside the enclosure against ingress of solid foreign
objects;
3) protection of the equipment inside the enclosure against harmful effects due to the
ingress of water.
b) Designations for these degrees of protection.
c) Requirements for each designation.
d) Tests to be performed to verify that the enclosure meets the requirements of this standard.
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 “enclosure” as it
applies to their equipment. However, it is recommended that for a given classification the
tests do not differ from those specified in this standard. If necessary, complementary
requirements may be included in the relevant product standard. A guide for the details to be
specified in relevant product standards is given in annex B.
For a particular type of equipment, a technical committee may specify different requirements
provided that at least the same level of safety is ensured.
This standard 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.
This standard is also applicable to empty enclosures provided that the general test
requirements are met and that the selected degree of protection is suitable for the type of
equipment to be protected.
Measures to protect both the enclosure and the equipment inside the enclosure against
external influences or conditions such as
– mechanical impacts
– corrosion
– corrosive solvents (for example, cutting liquids)
– fungus
– vermin
– solar radiation
– icing
– moisture (for example, produced by condensation)
– explosive atmospheres
---------------------- Page: 11 ----------------------
60529 © IEC:1989+A1:1999 – 9 –
and the protection against contact with hazardous moving parts external to the enclosure
(such as fans), are matters for the relevant product standard to be protected.
Barriers external to the enclosure and not attached to it and obstacles which have been
provided solely for the safety of personnel are not considered as a part of the enclosure and
are not dealt with in this standard.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.

3.1
enclosure
a part providing protection of equipment against certain external influences and, in any
*
direction, protection against direct contact [IEV 826-03-12] .
NOTE This definition taken from the existing International Electrotechnical Vocabulary (IEV) needs the following
explanations under the scope of this standard:
1) Enclosures provide protection of persons or livestock against access to hazardous parts.
2) Barriers, shapes of openings or any other means – whether attached to the enclosure or formed by the
enclosed equipment – suitable to prevent or limit the penetration of the specified test probes are considered
as a part of the enclosure, except when they can be removed without the use of a key or tool.
3.2
direct contact
contact of persons or livestock with live parts [IEV 826-03-05]
NOTE This IEV definition is given for information. In this standard “direct contact” is replaced by “access to
hazardous parts”.
3.3
degree of protection
