Degree of protection
Standard IEC 60364-5-51 lists and codifies a large number of external influences
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 first numeral.
The first 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.
