Dripping water when tilted at 15° |
Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of 15° from its normal position. A total of four positions are tested within two axes. Test duration: 2.5 minutes for every direction of tilt (10 minutes total Water equivalent to 3 mm rainfall per minute |
Test duration: 2.5 minutes for every direction of tilt (10 minutes total)Water equivalent to 3 mm rainfall per minute |

Spraying water |
Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with a counterbalanced shield. Test a) is conducted for 5 minutes, then repeated with the specimen rotated horizontally by 90° for the second 5-minute test. Test b) is conducted (with shield in place) for 5 minutes minimum. |
For a Spray Nozzle:Test duration: 1 minute per square meter for at least 5 minutes[2]Water volume: 10 litres per minute Pressure: 50–150 kPa For an oscillating tube: Test duration: 10 minutes Water Volume: 0.07 l/min per hole |

4 |
Splashing of water |
Water splashing against the enclosure from any direction shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with no shield. Test a) is conducted for 10 minutes. Test b) is conducted (without shield) for 5 minutes minimum. |
Oscillating tube: Test duration: 10 minutes, or spray nozzle |
|
5 |
Water Jets |
Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects. |
Test duration: 1 minute per square meter for at least 15 minutes Water volume: 12.5 litres per minute Pressure: 30 kPa at distance of 3 m |
|
6 |
Powerful Water Jets |
Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects. |
Test duration: 1 minute per square meter for at least 3 minutes Water volume: 100 litres per minute Pressure: 100 kPa at distance of 3 m |
