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.
