The first is related to resistance or protection to dust. While the second is related to water resistance.

Dust resistance

The digits used to indicate the resistance or protection to dust of a mobile device range from 0 to 6. So, the scale would be as follows:

  • 0: Without protection.
  • 1: Spheres with a diameter of 50 mm do not fully penetrate the device.
  • 2: Spheres with a diameter of 12.5 mm do not fully penetrate the device.
  • 3: Spheres with a diameter of 2.5 mm cannot penetrate the device.
  • 4: Spheres with a diameter of 1 mm do not enter the device.
  • 5: Dust can penetrate the device. However, it does so in amounts that will not affect its operation.
  • 6: Dust cannot penetrate the device.


On the other hand, the scale of resistance or protection to water is a little more extensive. It goes from 0 to 9 and the interpretation of the digits is given as follows:

  • 0: No protection. The water will enter easily and quickly.
  • 1: The device resists 10 minutes to drops falling 200 mm high.
  • 2: The device resists 10 minutes to drops of 3 to 5 mm cubic per minute and with a rotation of 15 °.
  • 3: The device resists 1 to 5 minutes to water spray with a rotation of up to 60 °.
  • 4: The device resists at least 10 minutes to a jet of water (10 liters per minute) from any angle.
  • 5: The device withstands a minimum of 3 minutes to a moderate jet of water (12.5 liters per minute) at less than three meters.
  • 6: The device can withstand a powerful jet of water (100 liters per minute) for at least 3 minutes.
  • 7: The device resists 30 minutes submerged at a depth of 1 meter.
  • 8: Endurance time varies by manufacturer. But it can be submerged up to 3 meters deep.
  • 9: Resistant to powerful jets (from 14 to 16 liters per minute) from different angles and distances.
