Protection against contact and ingress of solid objects Protection against ingress of water
0 No protection 0 No protection
1 Protected against ingress solid objects with a diameter
of more than 50 mm. No protection against deliberate
access, e.g. with a hand, but large surfaces of the body
are prevented from approach.
1 Protection against dripping water falling vertically. No harmful effect
must be produced (vertically falling drops).
2 Protected against penetration by solid objects with a
diameter of more than 12 mm. Fingers or similar
objects prevented from approach.
2 Protection against dripping water falling vertically. There must be no
harmful effect when the equipment (enclosure) is tilted at an angle
up to 15° from its normal position (drops falling a t an angle).
3 Protected against ingress of solid objects with a
diameter of more than 2.5 mm. Tools, wires etc. with a
thickness of more than 2.5 mm are prevented from
approach.
3 Protection against water falling at any angle up to 60° from the
vertical. There must be no harmful effect (spray water).
4 Protected against ingress of solid objects with a
diameter of more than 1 mm. Tools, wires etc. with a
thickness of more than 1 mm are prevented from
approach.
4 Protection against water splashed against the equipment
(enclosure) from any direction. There must be no harmful effect
(splashing water).
5 Protected against harmful dust deposits. Ingress of
dust is not totally prevented but the dust must not enter
in sufficient quantity to interface with satisfactory
operation of the equipment. Complete protection
against contact.
5 Protection against water projected from a nozzle against the
equipment (enclosure) from any direction. There must be no
harmful effect (water jet).
6 Protection against ingress of dust (dust tight).
Complete protection against contact.
6 Protection against heavy seas or powerful water jets. Water must
not enter the equipment (enclosure) in harmful quantities (splashing
over).
