Specifies an alphanumeric code for classifying the degrees of protection provided by enclosures for electrical equipment rated up to 72.5 kV. It covers protection of persons against access to hazardous parts and of equipment against ingress of solid foreign objects, dust, and harmful quantities of water. Tests, access, probes and object probes and other test equipment are specified. It is reproduced from IEC 60529 Ed 2.1:2001.

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 asregards:1) protection of persons against access to hazardous parts inside the enclosure;2) protection of the equipment inside the enclosure against ingress of solid foreignobjects;3) protection of the equipment inside the enclosure against harmful effects due to theingress 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 thisstandard.It 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. If 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 maintained under 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 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 atmospheresand 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 beenprovided solely for the safety of personnel are not considered as a part of the enclosure andare not dealt with in this standard.
