Dust and water resistance tests

IP tests (dust resistance)

Testing performed

  • Dust resistance tests (IP5X/IP6X) according to PN-EN 60529 and ISO 20653
 

Objects tested

  • elements of electrical and electronic equipment,
  • assemblies for machines and devices.
 

Test dust types used

  • Arizona (A2, A4) according to ISO 12103-1,
  • talk,
  • Portland cement,
  • others.

Test benches

  • chambers with vertical circulation of dust-air mixture of volumes 1 m3 and 0,3 m3.
 

Characteristics of the dust chamber of volume 1 m3

  • dimensions of the chamber workspace: (1000 x 1000 x 1000) mm,
  • the ability to perform tests at ambient temperature and at elevated temperature (up to 100°C),
  • the ability to perform tests at negative pressure,
  • access opening with a diameter of 80 mm, enabling the routing of power cables and vacuum hoses to the test objects inside the chamber,
  • possibility of coupling the chamber with an external drive system, e.g. in the case of tests on alternators.

Example test in dust chamber – alternator durability testing

IP tests (resistance to water)

Testing performed

  • resistance to dripping water (IPX1, IPX2)
  • resistance to rain (IPX3, IPX4) using a tube with oscillating movement,
  • resistance to spurts of water (IPX5, IPX6, IPX6K),
  • immersion (IPX7, IPX8),
  • resistance to high-pressure washing (IPX9, IPX9K).
