IP protection classes

The IP protection class code describes the protection of an enclosure against the penetration of foreign matter, contact with dangerous parts and intrusion of water.

The different types of effects are divided into individual IP classes. This makes it possible for users to compare the durability, resistance and suitable area of application of products.

We carry out the following protection class tests: 

 

Protection tests against the intrusion of water:

  • IP X1 = dripping water (drops falling vertically)
  • IP X2 = dripping water below 15° angle of enclosure
  • IP X3 = spray water at an angle of up to 60°
  • IP X4 = splash water from all directions
  • IP X5 = hose water
  • IP X6 = strong hose water
  • IP X7 = temporary immersion
  • IP X8 = continuous immersion
  • IP X9k = high-pressure steam cleaning

 

Waterproofness tests with overpressure for deeper diving depths can be carried out as a special test. We can also insert a dripping device and a nozzle into our chamber especially for the aviation industry.

Protection class tests against the penetration of foreign matter

  • IP 1X = test probe d = 50 mm (protection against the penetration of foreign matter >50 mm and protection against touching dangerous parts with the back of the hand)
  • IP 2X = test probe d = 12.5 mm, jointed test finger (protection against the penetration of foreign matter >12.5 mm and protection against touching dangerous parts with the finger)
  • IP 3X = test probe d = 2.5 mm (protection against the penetration of foreign matter >2.5 mm and protection against touching dangerous parts with tools)
  • IP 4X = test probe d = 1 mm (protection against the penetration of foreign matter >1 mm and protection against touching dangerous parts with a wire)
  • IP 5X = dust-proof and protection against touching dangerous parts with a wire
  • IP 6X = dust-tight and protection against touching dangerous parts with a wire
     

Different types of test dust can be used, like for example talcum, Arizona dust or a mixture of Portland cement and fly ash.

 

The standards and procedures in this area include the following:

  • DIN EN 60529 Degrees of protection provided by enclosures (IP Code)
  • RTCA DO-160 Waterproofness (Cat. W Drip Proof Test, Cat. R Spray Proof Test)
  • MIL-STD-810 Rain, Immersion
  • DNVGL-CG-0339 Enclosure
  • DIN 40050-9 Degrees of protection (IP-code)
  • ISO 20653 Road vehicles – Degrees of protection (IP code) – Protection of electrical equipment against foreign objects, water and access
