2
Dripping 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.
3
Spraying water
Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect.
4
Splashing water
Water splashing against the enclosure from any direction shall have no harmful effect.
5
Water jets
Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects.
6
Powerful water jets
Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects.
7
Immersion up to 1m
Ingress 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).
8
Immersion beyond 1m
The 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.
