10.3 Degrees of protection according
to IEC 60529
IEC 60529 establishes a classification system for degrees of
protection ensured by an enclosure which relates to electri-
cal equipment of a voltage rating up to 72.5 kV. The IP code
(IP = international protection) described in this standard
characterises the degrees of protection against access to
hazardous parts, ingress of solid foreign bodies and the
ingress of water which are ensured by an enclosure. It is
briefly summarized in Tab. 10/3.
