1Dripping waterDripping water (vertically falling drops) shall have no harmful effect.Test duration: 10 minutes

Water equivalent to 1mm rainfall per minute

2Dripping water when tilted up to 15°Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position.Test duration: 10 minutes

Water equivalent to 3mm rainfall per minute

3Spraying waterWater falling as a spray at any angle up to 60° from the vertical shall have no harmful effect.Test duration: 5 minutes

Water volume: 0.7 litres per minute
Pressure: 80–100 kN/m²

4Splashing waterWater splashing against the enclosure from any direction shall have no harmful effect.Test duration: 5 minutes

Water volume: 10 litres per minute
Pressure: 80–100 kN/m²

5Water jetsWater projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects.Test duration: at least 3 minutes

Water volume: 12.5 litres per minute
Pressure: 30 kN/m² at distance of 3m

6Powerful water jetsWater projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects.Test duration: at least 3 minutes

Water volume: 100 litres per minute
Pressure: 100 kN/m² at distance of 3m

7Immersion up to 1 mIngress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).Test duration: 30 minutes

Immersion at depth of 1m

8Immersion beyond 1 mThe equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.Test duration: continuous immersion in water

Depth specified by manufacturer
