This is an automated test chamber at our ALIS Barn Lamp manufacturing facility. Samples from every batch built are subjected to this test to confirm IPx6 capability is being maintained.
IPx6 specifies the protection of equipment against the harmful effects of powerful water jets from any direction. The nozzle in the clip is 12.5mm in diameter and delivers 100 litres per minute. The test lasts 3 minutes. The ALIS Barn Lamp is between 2.5 and 3 meters from the nozzle. The water pressure is not a fixed parameter but is varied to achieve the flow rate.
