EN 60529 outlines an international classification
system for the sealing effectiveness of
enclosures of electrical equipment against the
intrusion into the equipment of foreign bodies
(i.e. tools, dust, fingers) and moisture. This
classification system utilises the letters "IP"
("Ingress Protection") followed by two or three
digits. (A third digit is sometimes used. An "x"
is used for one of the digits if there is only one
class of protection; i.e. IPX4 which addresses
moisture resistance only.)
Degrees of Protection - First Digit
The first digit of the IP code indicates the
degree that persons are protected against
contact with moving parts (other than smooth
rotating shafts, etc.) and the degree that
equipment is protected against solid foreign
bodies intruding into an enclosure.

Degrees of Protection - Second Digit
The second digit indicates the degree of
protection of the equipment inside the
enclosure against the harmful entry of various
forms of moisture (e.g. dripping, spraying,
submersion, etc.)

The IP Code Symbols
The chart at the right illustrates the use of
special symbols in the IP classification
system. In the "1st digit" column, note the
grid-like symbols next to numbers 5 and 6. In
the "2nd digit" column numbers 3-8 are
symbolised by teardrop shaped symbols,
sometimes enclosed in a box or a triangle,
sometimes
symbols can be placed on equipment to
illustrate the IP protection provided.
No special protection.
Protection from a large part of the body
such as a hand (but no protection from
deliberate access); from solid objects
greater than 50mm in diameter.
Protection against fingers or other object
not greater than 80mm in length and
12mm in diameter.
Protection from entry by tools, wires, etc.,
with a diameter or thickness greater than
2.5mm.
Protection from entry by solid objects with
a diameter or thickness greater than
1.0mm.
Protection from the amount of dust that
would interfere with the operation of the
equipment.
Dust tight.
No special protection.
Protection from dripping water.
Protection from vertically dripping water.
Protection from sprayed water.
Protection from splashed water.
Protection from water projected from a
nozzle.
Protection
powerful jets of water.
Protection against immersion.
Protection against complete, continuous
submersion in water. Submersion depth
and time must be specified by the
enduser. The requirement must be more
onerous than IP67.

Note: EN 60529 does not specify sealing
effectiveness against the following:
mechanical damage of the equipment; the
risk of explosions; certain types of
moisture conditions, e.g. those that are
produced by condensation; corrosive
vapours; fungus; vermin.
