14.2 Test conditions
During the tests for IPXl to IPX6 the water temperature should not differ by more than 5 K from the temperature of the specimen under test. If the water temperature is more than 5 K below the temperature of the specimen a pressure balance shall be provided for the enclosure.
Adequate safety precautions should be taken when testing the equipment in the energized condition.
14.2.5 Test for second characteristic numeral 5 with the 6,3 mm nozzle
The test is made by spraying the enclosure from all practicable directions with a stream of
water from a standard test nozzle as shown in figure 6.
The conditions to be observed are as follows:
– internal diameter of the nozzle: 6,3 mm;
– delivery rate: 12,5 l/min ± 5 %;
– water pressure: to be adjusted to achieve the specified delivery rate;
– core of the substantial stream: circle of approximately 40 mm diameter at 2,5 m distance from nozzle;
– test duration per square metre of enclosure surface area likely to be sprayed: 1 min;
– minimum test duration: 3 min;
– distance from nozzle to enclosure surface: between 2,5 m and 3 m.
14.2.6 Test for second characteristic numeral 6 with the 12,5 mm nozzle
The test is made by spraying the enclosure from all practicable directions with a stream of water from a standard test nozzle as shown in figure 6.
The conditions to be observed are as follows:
– internal diameter of the nozzle: 12,5 mm;
– delivery rate: 100 l/min ± 5 %;
– water pressure: to be adjusted to achieve the specified delivery rate;
– core of the substantial stream: circle of approximately 120 mm diameter at 2,5 m distance from nozzle;
– test duration per square metre of enclosure surface area likely to be sprayed: 1 min;
– minimum test duration: 3 min;
– distance from nozzle to enclosure surface: between 2,5 m and 3 m.
