IP CLASS

The IP code is a system which is used in Europe to determine the compactness for electronic devices. The code helps us to determine degree of protection provided against intrusion such as dust and water. The content of the code is presented in the IEC 60529 standard.


The label consists of the IP (Ingress Protection) text as well as from two numbers and optional letter markings.



The first number tells the protection against outside objects and dust. The larger the number the more compact the device.0: No protection.

  • 1: Protected against large objects, diameter more than 50 mm.
  • 2: Protected against medium objects, diameter more than 12,5 mm
  • 3: Protected against small objects, diameter more than 2,5 mm
  • 4: Protected against very small objects, diameter more than 1 mm
  • 5: Protected against dust, full dustproofness is not required but harmful dust accruals are not allowed.
  • 6: Full protection, dustproof.

The second number tells the protection against water and humidity. The larger the number the better the resistance against humidity

  • 0: No protection against water.
  • 1: Protection against vertically dripping water.
  • 2: Protection against dripping water when tilted at most at 15 degrees.
  • 3: Protection against water falling as a spray at any angle up to 60 degrees.
  • 4: Protection against splashing of water.
  • 5: Protection against water jets from all angels.
  • 6: Protection against strong water jets from all angels.
  • 7: Resists occasional immersion under water.
  • 8: Resists continuous immersion under water.
