FOREWORD
1) The formal decisions or agreements of the I EC on technical matters, prepared by Technical Committees on 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.
2) They have the form of recommendations for international use and they are accepted by the National Committees in
that sense.
3) In order to promote international unification, the IEC expresses the wish that all National Committees should adopt
the text of the IEC recommendation for their national rules in so far as national conditions will permit. Any
divergence between the IEC recommendation and the corresponding national rules should, as far as possible, be
clearly indicated in the latter.

DEGREES OF PROTECTION PROVIDED
BY ENCLOSURES
(IP Code)
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
s of equipment to
consulted to determine the degrees of protection available and the pa rt
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.
I E C 529 takes account of experiences with the first edition, and
This second edition of
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.
1. Scope
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:
for degrees of protection provided by enclosures of electrical equipment as
a) Definitions
regards:
rts inside the enclosure;
1) protection of persons against access to hazardous pa
protection of the equipment inside the enclosure against ingress of solid foreign
2)
objects;
protection of the equipment inside the enclosure against harmful effects due to the
3)
ingress of water.
b) Designations for these degrees of protection.
c) Requirements for each designation.

529©IEC — 9 —
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.
Measures to protect both the enclosure and the equipment inside the enclosure against
external influences or conditions such as
– mechanical impacts
– corrosion
– corrosive solvents (e. g. cutting liquids)
– fungus
–
vermin
–
solar radiation
– icing
– moisture (e. g. produced by condensation)
– explosive atmospheres
and the protection against contact with hazardous moving pa rts external to the
enclosure (such as fans),
are matters for the relevant product standard.
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.
3. Definitions
For the purpose of this standard, the following definitions apply:
3.1 Enclosure
A part providing protection of equipment against ce rtain external influences and, in
any direction, protection against direct contact (IEV 826-03-12) *.
* I E C 50(826).
529 © I EC - ll —
Note. — This definition taken from the existing International Electrotechnical Vocabulary (IEV) needs the
following explanations under the scope of this standard:
rts.
1) Enclosures provide protection of persons or livestock against access to hazardous pa
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 pa rt 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 pa rts (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
The extent of protection provided by an enclosure against access to hazardous pa rts,
against . ingress of solid foreign objects and/or against ingress of water and verified by
standardized test methods.
IP Code
3.4
A coding system to indicate the degrees of protection provided by an enclosure against
s, ingress of solid foreign objects, ingress of water and to give
access to hazardous pa rt
additional information in connection with such protection.
3.5 Hazardous part
A part that is hazardous to approach or touch.
Hazardous live part
3.5.1

A live part which, under cert
shock (see IEC 536, at present Document 64(CO)196).
3.5.2 Hazardous mechanical part
A moving part, other than a smooth rotating shaft, that is hazardous to touch.
3.6 Protection provided by an enclosure against access to hazardous parts
The protection of persons against
– contact with hazardous low-voltage live pa rts,
– contact with hazardous mechanical pa rts,
– approach to hazardous high-voltage live pa rts below adequate clearance inside an
enclosure.
Note. — This protection may be provided
—by means of the enclosure itself,
by means of barriers as part of the enclosure or distances inside the enclosure.
—
3.7 Adequate clearance for protection against access to hazardous parts
A distance to prevent contact or approach of an access probe to a hazardous pa rt .

STOPNJA ZAŠČITE, KI JO ZAGOTAVLJA OHIŠJE (KODA IP)

Predgovor
1) Uradne odločitve ali sporazumi IEC o tehničnih vprašanjih, pripravljeni v tehničnih odborih, v katerih so prisotni vsi nacionalni
komiteji, ki jih tema zanima, izražajo, kolikor je mogoče, mednarodno soglasje o obravnavani temi.
2) Publikacije IEC imajo obliko priporočil za njihovo uporabo na mednarodni ravni in jih kot takšne sprejmejo nacionalni komiteji
IEC.
3) Da bi pospeševali mednarodno poenotenje, so se nacionalni komiteji IEC zavezali, da bodo v svojih nacionalnih in regionalnih
standardih čim pregledneje uporabljali mednarodne standarde. Vsako odstopanje med standardom IEC in ustreznim
nacionalnim ali regionalnim standardom je treba v slednjem jasno označiti.
Uvod
Ta standard je pripravil tehnični odbor IEC/TC 70 "Stopnja zaščite, ki jo zagotavlja ohišje".

Ta druga izdaja IEC 529 nadomešča prvo izdajo iz leta 1976.

Besedilo tega standarda temelji na naslednjih dokumentih:

Pravilo šestih mesecev Poročilo o glasovanju Dvomesečni postopek Poročilo o glasovanju
70(CO)13 70(CO)15 70(C0)16 70(CO)17

Vse informacije o glasovanju za potrditev tega standarda je mogoče najti v poročilih o glasovanju, ki so
podani v gornji preglednici.
V tem standardu so navedene naslednje publikacije IEC:

IEC 50(826) (1982) Mednarodni elektrotehniški slovar – 826. del: Električne inštalacije zgradb

SIST EN 60529 : 1997
Stopnja zaščite, ki jo zagotavlja ohišje (koda IP)

Uvod
Ta standard opisuje sistem za razvrščanje stopenj zaščite, ki jih zagotavljajo ohišja električne opreme.
Čeprav je ta sistem primeren za uporabo pri večini vrst električnih naprav, se ne sme domnevati, da so
vse navedene stopnje zaščite uporabne za določeno posebno vrsto opreme. V posvetovanju s
proizvajalcem opreme naj se določijo razpoložljiva stopnja zaščite in deli opreme, na katerih se bo
uporabljala navedena stopnja zaščite.

Sprejetje tega sistema razvrščanja bo, kjer je to mogoče, spodbujalo enotnost metod opisovanja zaščite,
ki jo zagotavlja ohišje, in preskusov za dokazovanje različnih stopenj zaščite. Prav tako naj bi se
zmanjšalo število vrst preskusnih naprav, potrebnih za preskušanje široke palete izdelkov.

Ta druga izdaja IEC 529 upošteva izkušnje s prvo izdajo in pojasnjuje zahteve. Zagotavlja izbirno
podaljšanje kode IP z dodatno črko A, B, C ali D, če je dejanska zaščita oseb pred dostopom do nevarnih
delov večja od zaščite, ki jo določa prva karakteristična števka.

Na splošno velja, da naj bi bila ohišja s kodo IP po prvi izdaji primerna za isto kodo v skladu s to izdajo.

1 Področje uporabe
Ta standard se uporablja za razvrstitev stopenj zaščite, ki jih zagotavljajo ohišja za električno opremo z
naznačeno napetostjo, ki ne presega 72,5 kV.

2 Predmet uporabe
Predmet tega standarda je podati:

a) definicije stopenj zaščite, ki jih zagotavljajo ohišja električne opreme glede:

1) zaščite oseb pred dostopom do nevarnih delov znotraj ohišja,

2) zaščite opreme znotraj ohišja pred vdorom trdnih tujkov,

3) zaščite opreme znotraj ohišja pred škodljivimi učinki zaradi vdora vode,

b) označitve teh stopenj zaščite,

c) zahteve za vsako označitev,

d) preskuse, ki jih je treba izvesti za preverjanje, ali ohišje izpolnjuje zahteve tega standarda.
