● The degrees of protection provided by the
enclosures are defined by standards IEC 60529 (IP)
and IEC 62262 (IK).
● 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).
● 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.
