IP Ratings Quick Reference Chart

The IP rating standard is a classification which rates the degree of protection of eqiupment casing, against the ingress of solids and liquids, which may in turn affect equipment function.

IP rating do not cover chemical or erosion resistance, damages to finishes, etc. The rating comprises two numbers as described below:

  • The first number indicates the projection level against solid particles such as dust. Maximum level is 6.
  • The second number indicates the protection level against liquids such as water. Maximum level is 8
  • The bigger the number, the better the protection.
  • The highest IP rating is IP69K. All tests with the letter “K” are defined by ISO 20653.
  • Number X means not tested.
  • Number 0 means not protected.

The following is a quick reference for the IP ratings.

IPXY First Digit – SOLIDS Second Digit – LIQUIDS Remarks
IPX1 Untested against solids Protected against dripping water with vertically falling drops
IPX2 Untested against solids Protected against dripping water when tilted up to 15 degrees from normal position. The test details include a test duration of 10 minutes and a water equivalent to 1mm rainfall per minute.
IPX3 Untested against solids Protected from water spray less than 60 degrees from vertical. The test details include a test duration of 10 minutes and a water equivalent to 3mm rainfall per minute.
IPX4 Untested against solids Protected from water spray from any direction.
IPX5 Untested against solids Protected from low-pressure water jets from any direction.
IPX6 Untested against solids Protected from high-pressure water jets from any direction.
IPX6K Untested against solids Protected from very high-pressure water jets from any direction.
IPX7 Untested against solids Protected from water for 30mins.
Depending on size of test sample, the highest point must be >150mm below water surface, or the lowest point must be >1m.
For example, if an object is 1m tall, then the top part must be submerged at least 150mm below surface. This means the lowest point is 1.15m deep.
IPX8 Untested against solids Protected from long-term immersion up to a specified pressure and depth greater than 1m. Normally, at least 3m deep.
Specs to be determined by manufacturers.
IPX9K Untested against solids Protected from steam-jet cleaning, i.e. close-range high pressure, high-temperature spray downs.
