10 min. / 1mm rainfall per min. |
| 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. |
10 min. / 3mm rainfall per min. |
| 3 |
Spraying water |
Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect. |
5 min. / 0.7 litres per min. Pressure: 80–100 kN/m² |

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). |
30 min. / Immersion at depth of 1m |
| 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. |
