IP-Code figure definitions
Explanation to spray water protected (IP) systems and their environment.
This system, described in IEC 60529, was developed to represent standard values for respective protection:
a) Contact with, and ingress of, fixed foreign objects
b) The ingress of liquids to which the inside is to be exposed.
The first digit describes the level of protection for life, contacting objects and the intrusion of foreign bodies. The second digit describes the level of protection against
the ingress of liquids. The larger the first and second digits are, the greater afforded protection is, e.g. IP55 must also meet the requirements of all lower protection
levels, such as IP22, IP23, IP34 and IP54.
1. Code figure Definition Remark
0 Not protected
1 Protected against access to hazardous parts by the back of the hand.
Protected against fixed foreign objects Ø ≥ 1.969” 50 mm.
2 Protected against access to hazardous parts with a finger.
Protected against fixed foreign objects Ø ≥ .492” 12.5 mm.
3 Protected against access to hazardous parts with a tool.
Protected against fixed foreign objects Ø ≥ .098” 2.5 mm.
4 Protected against access to hazardous parts with a wire.
Protected against fixed foreign objects Ø ≥ .039” 1 mm.
5 Protected against access to hazardous parts with a wire. Ingress of dust is not completely blocked. But dust
Dust protected. may not penetrate to the extent that satisfactory
operation of the device or safety is impaired.
6 Protected against access to hazardous parts with a wire.
Dustproof. No ingress of dust.
0 Not protected
1 Protected against dropper.
2 Protected against dropper when the shell is tipped as much as 15°.
3 Protected against spray water Up to 60° of either side of the vertical, such spray
water shall have no harmful effects.
4 Protected against splash water On the shell from all directions, no harmful effects
shall be incurred.
5 Protected against jets of water.
6 Protected against strong jets of water.
7 Protected against the effects of temporary submersion in water. Water may not ingress in a volume that would cause
harmful effects when the shell is submerged in water
for 30 min at a depth of 1 m.
8 Protected against the effects of continuous submersion in water. Water may not ingress in a volume that would
cause harmful effects when the shell is continuously
submerged in water under conditions agreed between
manufacturer and user.
However, these conditions must be more stringent
than those described under code figure 7.
9k Protected against water from high-pressure or steam cleaning.
