IP RATING

The IP rating normally has two numbers:
1. Level of protection from solid objects or materials
2. Level of protection from liquids (water)

NO. EXAMPLE SOLID PROTECTION NO. EXAMPLE WATER PROTECTION

0 No special protection 0 No special protection

Protection from a large part of the body
1 such as a hand (but no protection from 1 Protection against condensation
deliberate access); from solid objects
greater than 50mm in diameter

2 Protection against fingers or other objects 2 Protection against water droplets
not greater than 80mm in length and
12mm in diameter deflected up to 15° from vertical

3 Protection from entry by tools, wires etc, 3 Protection against spray up to 60°
from vertical
with a diameter of 2.5mm or more

4 Protection against solid 4 Protection against water spray from
all directions
bodies larger than 1mm

5 Protection against dust that may 5 Protection against low pressure

6 Totally dust-tight 6 Protection against high pressure

IP65 7 Protection against temporary
immersion

Protection against prolonged
8 effects of submersion under
Ingress Protection pressure. Submersion depth to be
specified.*

* e.g. IP 68 @ 1bar = dust-tight and permanent protection to 1 bar pressure (9m water depth)
