IEC 60529 pdf download – Degrees of protection provided by enclosures (IP Code)
1Scope and object
This standard applies to the classification of degrees of protection provided by enclosures forelectrical equipment with a rated voltage not exceeding 72,5 kV.
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.lt will remain the responsibility of individual technical committees to decide on the extent andmanner in which， the classification is used in their standards and to define “enclosure” as itapplies to their equipment. However。 it is recommended that for a given classification thetests do not differ from those specified in this standard. lf necessary，complementaryrequirements may be included in the relevant product standard. A guide for the details to bespecified in relevant product standards is given in annex B.
For a particular type of equipment, a technical committee may specify different requirementsprovided that at least the same level of safety is ensured.
This standard deals only with enclosures that are in all other respects suitable for theirintended use as specified in the relevant product standard and which from the point of view ofmaterials and workmanship ensure that the claimed degrees of protection are maintainedunder the normal conditions of use.
This standard is also applicable to empty enclosures provided that the general testrequirements are met and that the selected degree of protection is suitable for the type ofequipment to be protected.
Measures to protect both the enclosure and the equipment inside the enclosure againstexternal influences or conditions such as
mechanical impacts
corrosion
corrosive solvents (for example,cutting liquids)fungus
vermin
solar radiationicing
moisture (for example. produced by condensation)explosive atmospheres
and the protection against contact with hazardous moving parts external to the enclosure l(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 beenprovided solely for the safety of personnel are not considered as a part of the enclosure andare 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 certain external influences and，in anydirection,protection against direct contact [IEV 826-03-12]”.
NOTE This definition taken from the existing International Electrotechnical Vocabulary (IEV’) needs the followingexplanations 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 specifried test probes are consideredas 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 lEV definition is given for information.In this standard “direct contact” is replaced by “access tohazardous parts”.
