Ingress Protection Rating

  • The Ingress Protection rating defines and standardizes a device's level of protection against water and object intrusion.
  • The first digit defines the level of protection against object intrusion.
  • The second digit defines the level of protection against water ingress.

  • However, it does not prevent water, fog or frost from adhering to the exterior.
