IPX3 and IPX4 Oscillating Tube Testing Equipment

1.Introduction

The oscillating tube testing equipment can meet the test requirements of IEC60529 clause 14.2.3 and 14.2.4, it is to verify protection against spraying (IPX3) and splashing water (IPX4), and widely used in the industries of electronics, luminaire, electric components, auto parts and etc..

The IPX3 and IPX4 waterproof test equipment includes oscillating tubes (R200 to R1600), turntable, water tank, control units (touch screen+PLC), flowmeter and etc.. The oscillating tube is made of SUS304 stainless steel.

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). And  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. And 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 the time for one complete oscillation (2*360°) being about 12s. The duration of the test is 10min.
