Level | Protected against | Effective against |
0 | - | No protection |
1 | Dripping water | Vertically falling drops (1 mm rainfall per minute) |
2 | Dripping water when tilted up to 15° | Vertically dripping water when the enclosure is tilted up to 15° (3 mm rainfall per minute) |
3 | Spraying water | Water falling as a spray at any angle up to 60° (0.7 l/min at 80‑100 kPa) |
4 | Splashing of water | Water splashing from any direction (10 l/min at 80‑100 kPa) |
5 | Water jets | Water projected by a nozzle from any direction (12.5 l/min at 30 kPa at a distance of 3 m) |
6 | Powerful water jets | Water projected in powerful jets from any direction (100 l/min at 100 kPa at a distance of 3 m) |
6K | Powerful water jets with increased pressure | Water projected in powerful jets from any direction under elevated pressure (75 l/min at 1000 kPa at a distance of 3 m) |
7 | Immersion up to 1 m | Submersion in water up to 1 m for 30 minutes |
8 | Immersion beyond 1 m | Continuous immersion in water at a depth generally up to 3 m (water can enter but only in such a manner that it produces no harmful effects) |
9K | Powerful high temperature water jets | Protected against close‑range high pressure, high temperature spray downs (14‑16 l/min at 8000‑10000 kPa at a distance of 0.1‑0.15 cm, 80 °C) |
