What is the IP Rating of a product,
and what does it mean?
The IP Code (or International
Protection Rating, sometimes also interpreted as Ingress Protection
Rating) consists of the letters IP followed by two digits and an
optional letter. As defined in international standard IEC 60529, it
classifies the degrees of protection provided against the intrusion
of solid objects (including body parts like hands and fingers),
dust, accidental contact, and water in electrical enclosures. The
standard aims to provide users more detailed information than vague
marketing terms such as "waterproof".
May also be known as “Index
The digits ('characteristic
numerals') indicate conformity with the conditions summarized in the
tables below. Where there is no protection rating with regard to one
of the criteria, the digit is replaced with the letter X.
For example, an electrical socket
rated IP22 is protected against insertion of fingers and will not be
damaged or become unsafe during a specified test in which it is
exposed to vertically or nearly vertically dripping water. IP22 or
IP2X are typical minimum requirements for the design of electrical
accessories for indoor use.
- The first digit indicates the level
of protection that the enclosure provides against access to
hazardous parts (e.g., electrical conductors, moving parts) and the
ingress of solid foreign objects.
Level Object size protected
No protection against contact and ingress of objects
1 >50 mm
Any large surface of a human body, such as the back of a hand, but
no protection against deliberate contact
with a body part
2 >12.5 mm
Fingers or similar objects
3 >2.5 mm
Tools, thick wires, etc.
4 >1 mm
Most wires, screws, etc.
5 dust protected Ingress of dust is not entirely prevented, but it must not enter in
sufficient quantity to interfere with the
satisfactory operation of the equipment; complete protection
6 dust tight
No ingress of dust; complete protection against contact
- Protection of the equipment inside
the enclosure against harmful ingress of water.
Level Protected against, Details
No protection against water
1 dripping water Dripping water (vertically falling drops) shall have no harmful
2 dripping water
Vertically dripping water shall have no harmful effect
when tilted up to 15° when the enclosure is tilted at
an angle up to 15° from its normal position.
3 spraying water
Water falling as a spray at angles up to 60° from the vertical shall
have no harmful effect.
4 splashing water
Water splashing against the enclosure from any direction shall have
no harmful effect.
5 water jets
Water projected by a nozzle against enclosure from any direction
shall have no harmful effects.
6 powerful water jets
Water projected in powerful jets against the enclosure shall have no
7 immersion up to 1 m
Ingress of water in harmful quantity shall not be possible when the
immersed in water under defined conditions of pressure and time (up
to 1 m of submersion).
8 immersion beyond 1 m
The equipment is suitable for continuous immersion in water under
conditions which shall be specified
by the manufacturer. NOTE: Normally, this will mean that the
equipment is hermetically sealed. However,
with certain types of equipment, it can mean that water can enter
but only in such a manner that produces
no harmful effects.
