IP Testing (Ingress Protection Testing)

IP testing (Ingress Protection testing) evaluates a product's capacity requirements for the protection of electrical equipment against ingress of foreign objects, water, dust, and so on. There is an international classification system within the IEC 60529 standard for Ingress Protection Testing.

IP Codes are made up of the letters IP and two numbers. The first code number stands for the degree of protection against access to dangerous parts and solid foreign objects. The second code number stands for the degree of protection against liquids.

IP Testing against access to dangerous parts and solid foreign objects

  • IP0X: No protection 
  • IP1X: Protection against solid objects greater than 50 mm such as the back of a hand
  • IP2X: Protection against solid objects greater than 12.5 mm such as a finger or a similar object
  • IP3X: Protection against solid objects greater than 2.5 mm such as a screwdriver
  • IP4X: Protection against a solid object greater than 1 mm such as a wire
  • IP5X: Protection against dust. The test is performed with or without negative pressure. The ingress of dust (tested with talcum powder) is allowed as long as the functionality of the device is still guaranteed.
  • IP6X: Protection against dust. The test is performed with negative pressure. The ingress of dust (tested with talcum powder) is not allowed.

"To evaluate the test, a high-voltage test (dielectric strength test) is often performed."

IP Testing against water

  • IPX0: No protection
  • IPX1: Protection against dripping water
  • IPX2: Protection against vertically dripping water at angle of 15 degrees
  • IPX3: Protection against spraying water
  • IPX4: Protection against splashing water  
  • IPX5: Protection against jets of water  
  • IPX6: Protection against powerful jets
  • IPX7: Protection against 1 m deep submersion in water for 30 minutes with no harmful extent of water ingress.
  • IPX8: Protection against a more than 1 m deep submersion for over 30 minutes with no harmful extent of water ingress.
  • IPX9: Protection against powerful high temperature water jets with no harmful extend of water ingress
