0 | No protection. |
1 | Falling water equivalent to 3-5mm rainfall per minute for a duration of 10 minutes. Unit is placed in its normal operating position. |
2 | Falling water when tilted up to 15 degrees - Same as IPx1 but unit is tested in 4 fixed positions - tilted 15 degrees in each direction from normal operating position. |
3 | Protected against spraying water - Water spraying up to 60 degrees from vertical at 10 liters/min at a pressure of 80-100kN/m2 for 5 min. |
4 | Protected against splashing water - Same as IPx3 but water is sprayed at all angles. |
5 | Protected against water jets - Water projected at all angles through a 6.3mm nozzle at a flow rate of 12.5 liters/min at a pressure of 30kN/m2 for 3 minutes from a distance of 3 meters. |
6 | Protected against heavy seas - Water projected at all angles through a 12.5mm nozzle at a flow rate of 100 liters/min at a pressure of 100kN/m2 for 3 minutes from a distance of 3 meters. |
7 | Protected against water immersion - Immersion for 30 minutes at a depth of 1 meter. |
8 | Protected against water submersion - The equipment is suitable for continual submersion in water under conditions which are identified by the manufacturer. |
9K | Protected against close-range high pressure, high temperature spray downs. (DIN 40050-9, not part of IP classification) |
