                how to test IPX3 and IPX4 Water Splash nozzle?

                2025-08-01

                how to test IPX3 and IPX4 Water Splash nozzle?

                here is the Instructions for IPX3 and IPX4 Water Splash Nozzle Testing:

                IPX3 Water Splash Examination:

                Examination Configuration: The IPX3 splash examination can be conducted using a swinging tube or a spray nozzle, depending on the size of the device. Water flow is regulated with a flow meter. In the swinging tube configuration, water pressure is modified to achieve the correct flow rate. The tube swings 120 degrees (60 degrees on either side of the vertical) in approximately 4 seconds for a complete oscillation. The entire examination lasts 5 minutes, with the enclosure positioned at the center of the tube.

                Water Dispensation: The portable spray nozzle is utilized for larger enclosures. Pressure is modified to deliver 10 liters per minute (within a range of 50-150 kPa). The nozzle is positioned 60 degrees from the vertical, and a counterbalance shield is employed.

                Examination Duration: The duration of the examination is one minute per square meter, with a minimum of five minutes.

                Assessment: Following the examination, the unit is cleaned and inspected for water penetration. Additional units can be examined at the request of the manufacturer for design assurance.

                IPX4 Water Spray Examination:

                Examination Configuration: IPX4 examination, similar to IPX3, can utilize an oscillating tube or a handheld spray nozzle. The counterbalance shield is eliminated for IPX4 with controlled water flow.

                Water Usage: The tube oscillates nearly 360 degrees. The spray distance is 200 mm, with a flow rate of 0.07 liters/min per hole, examined for 10 mins. The handheld nozzle sprays the enclosure from all directions at 10 liters/min.

                Examination Duration: The duration of the test depends on the size, with a minimum of five mins per square meter.

                Assessment: Post-examination, the unit is cleaned, opened, and evaluated for pass/fail. Water should not disrupt the equipment’s intended operation or endanger user safety.
