Technical annexes

Degrees of protection provided

by enclosures

b

b

The degrees of protection provided by the

enclosures are defined by standards IEC 60529

(IP) and IEC 62262 (IK).

b

b

Degrees of protection are indicated by the

letters IP followed by two characteristic numerals.

The numerals show the degree of protection

offered by the enclosure against access to

dangerous parts, the penetration of of solid

bodies (1st numeral), and against the penetration

of liquids (2nd numeral).

b

b

The protection against external mechanical

impact is indicated by the letters IK followed

by a characteristic group numeral.

Note:

Many EN European standards are harmonised

with international IEC standards.

This is the case with enclosure protection standards:

- EN 60529 = IEC 60529.

- EN 62262 = IEC 62262.
