IPX3 and IPX4 Oscillating Tube Test Chamber

1.Introduction

IPX3 and IPX4 oscillating tube test chamber can meet the test requirements of IEC60529 clause 14.2.3 and 14.2.4. It is to simulate the electronics, luminaire, electric components and auto parts under the conditions of spraying water and splashing water, and then to check if they can meet the requirement.

The IPX3 and IPX4 waterproof test chamber includes oscillating tubes (R200 to R600), turntable, water tank, control units (touch screen+PLC), flowmeter and etc.. The oscillating tube, turntable and walls are made of SUS304 stainless steel. The test chamber is built-in a water tank, the water can be recycled. 4 casters are placed on the bottom of the chamber to make it can be moved easily.

Test conditions for IPX3 and IPX4 tests:

For IPX3 test, the oscillating tube has spray holes over an arc of 60° either side of the centre point (the other holes are blocked). The total flow rate is adjusted as standard requirement, place the sample at the center point of the semicircle, the tube is caused to oscillate through an angle of 120°, 60° on either side of the vertical. The time for one complete oscillation (2*120°) being about 4s, and test duration being 5min.

For IPX4 test, the oscillating tube has spray holes over the whole 180’’ of the semicircle. The total flow rate is adjusted according to the standard requirement, and measured with a flowmeter. The tube is caused to oscillate through an angle of almost 360°, 180° on either side of the vertical. And time for one complete oscillation (2*360°) being about 12s. The duration of the test is 10min.
