IP codes explained


IP is a coding system defined by the IEC 60529 to indicate the degrees of protection provided by an enclosure.
The aim of this is to give information regarding the accessibility of live parts against ingress of water and other foreign bodies.

     

First digit
(foreign bodies
protection)

     
     
     
 

Code letters
(international Protection)

IP68

Second digit
(water protection)

 

 

1st digit

Degree of protection

2nd digit

Degree of protection

0

No protection against accidental contact.
No protection against solid foreign bodies.

0

No protection against water

1

Protection against contact with any large area by hand and against large solid foreign bodies with a diameter bigger than 50 mm.

1

Drip-proof.
Protection against vertical water drips.

2

Protection against contact with the fingers.
Protection against solid foreign bodies with a diameter bigger than 12 mm.

2

Drip-proof.
Protection against water drips up to a 15? angle.

3

Protection against tools, wires or similar objects with a diameter
bigger than 2.5 mm.
Protection against small solid bodies with a diameter bigger than 2.5 mm.

3

Spray-proof.
Protection against diagonal water drips up to a 60? angle.

4

Same as 3 however diameter is bigger than 1 mm.

4

Splash-proof.
Protection against splashed water from all directions.

5

Full protection against contact. Protection against interior injurious dust deposits.

5

Hose-proof.
Protection against water (out of a nozzle) from all directions.

6

Total protection against contact.
Protection against penetration of dust.

6

Protection against temporary fl ooding.

 

7

Protection against temporary immersions.

 

The UTO, UTS, JBX, Clipper and UTL series
offers high sealing performance IP68 / 69K?
Even in dynamic situations.

 

8

Protection against water pressure.
Pressure to be specifi ed by supplier.

In addition to the IEC 60529 we conjointly use the DIN 40050 part 9
which are dedicated to road vehicles. The main differences are:
? First digit: 5 replaced by 5K, 6 by 6K. In the DIN the tested
equipment is not depressurized as it is in the IEC.
? Second digit: 5K and 6K has been added and are equivalent
respectively to 5 and 6 but with higher pressure.
9K which represents the High pressure cleaning.

9K

High pressure hose-proof.
Protection against high pressure water
(out of a nozzle) from all directions.
