International Protection code
The International Protection code, sometimes called the Ingress Protection code,
classifies the protection given by an enclosure against the touching of live parts,contact with moving parts and protection against the ingress of solid bodies.
It additionally specifies protection against the harmful ingress of liquids.
Two digits are used to describe its protection rating, called the IP code.
Example. IP65 is dust tight and jet proof
First digit-Protection against solid objects
0. No protection.
1. Protection against large, sized bodies. eg hands.2. Protection against medium, sized bodies. eg fingers.
3. Protection against small bodies, 2.5mm or greater eg tools, wire
4. Protection against very small bodies, 1mm or greater
5. Protection against harmful deposits of dust (dust proof).
6. Complete protection against deposits of dust (dust tight).
Second digit-Protection against liquids
0. No protection.
1. Protection against vertically falling drops of water.
2. Protection against drops of water up to 15 from the vertical (drip proof).
3. Protection against rain falling up to 60 from the vertical (rain proof).
4. Protection against splashed water from any angle (splash proof).
5. Protection against jets of water from any angle (jet proof).
6. Protection against water from heavy seas. eg water tight for marine deck use.
7. Protected against immersion for a defined period.
8. Protected against immersion for an indefinite period.
IP Protection class
Protection against contact and infiltration of water and dirt
In many ennvironments electronical devices must stand rough conditions and work for their
indetnded period of time nevertheless they are set out to dirt, dust and humidity. IP protection
classes define, how and where they can be used without getting a safety risk. Especialy in
medical areas the safety is very important for the device and all above for the patients.
The following table shows the different IP protection classes:
IP Protection classes
IP Characteristic 1 for protectionagainst contact IP Characteristic 2 for waterproofing

contact, Protection against dust
deposit
5 Protection from water projected from a nozzle
6 Complete protectionm against
contact, Protection from
infiltration of dust
6 Protection against heavy seas, or powerful jets of
water.
7 7 Protection against immersion
8 8 Protection against complete, continuous submersion in
water.
9 9 Protection against the ingress of water form all
directions even under greatly high pressure on the
housing. (High-pressure/steam cleaner, 80-100 bar)
