IEC Test 60529, IP54
IP-5x, Dust-Tight
The dust test required the units to be placed in a 1 m³ dust test chamber and subjected to 2 kg/m³ of Talcum powder. The test duration was 8 hours. After the test, units were fully functional.
IP-x4, Water Spray
The water spray test challenged the unit to withstand 10 minutes of continuous water flow through a 400 mm tube at a rate of 1.8 L/min from 25 different spray nozzles. After the water test, the units were fully functional.
