Degree of protection
Standard IEC 60364-5-51 lists and codies a large number of external inuences to
which electrical installations can be subjected, including the presence of water, solid
objects, shocks, vibrations, corrosive substances, etc.
IP code
Standard IEC 60529 (IP code, February 2001) indicates the degrees of protection
provided by an enclosure for electrical devices against access to hazardous parts,
against penetration of solid foreign objects and against penetration of water.
These standards do not apply for the protection against the risks of explosion or
conditions such a humidity, corrosive vapour, fungus or vermin.
The IP code is made up of two characteristic numerals and can include an additional
letter when the actual protection for persons against access to the hazardous parts is
better than that indicated by the rst numeral.
The rst numeral characterises the protection provided against the ingress of solid
foreign objects and the protection of persons.
The second numeral characterises the protection provided against the ingress of
water with harmful effects.
