1Dripping waterVertically falling drops (1 mm rainfall per minute)
2Dripping water when tilted up to 15°Vertically dripping water when the enclosure is tilted up to 15° (3 mm rainfall per minute)
3Spraying waterWater falling as a spray at any angle up to 60° (0.7 l/min at 80‑100 kPa)
4Splashing of waterWater splashing from any direction (10 l/min at 80‑100 kPa)
5Water jetsWater projected by a nozzle from any direction (12.5 l/min at 30 kPa at a distance of 3 m)
6Powerful water jetsWater projected in powerful jets from any direction (100 l/min at 100 kPa at a distance of 3 m)
6KPowerful water jets with increased pressureWater projected in powerful jets from any direction under elevated pressure (75 l/min at 1000 kPa at a distance of 3 m)
7Immersion up to 1 mSubmersion in water up to 1 m for 30 minutes
8Immersion beyond 1 mContinuous 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)
