| 4K | splash water with increased pressure. Ingress Protection Test Equipment |
Test conditions:
IPX1:
The test is made with a device which produces a uniform flow of water drops over the whole area of the enclosure.
The turntable on which the enclosure is placed has a rotation speed of 1 r/min and the eccentricity (distance between turntable axis and specimen axis) is approximately 100 mm.
The duration of test is 10 min.
IPX2:
The enclosure is tested for 2.5 min in each of four fixed positions of tilt.
These positions are 15° on either side of the vertical in two mutually perpendicular planes (see figure 3b)).
The total duration of the test is 10 min.
IPX3:
The oscillating tube is provided with spray holes over an arc of 60° either side of the centre point. The support is not perforated.
The enclosure to be tested is placed at the centre point of the semicircle. The tube is caused to oscillate through an angle of 1 20°, 60° on either side of the vertical, the time for one complete oscillation (2 × 1 20°) being about 4 s and the test duration being 5 min.
The enclosure is then turned through an horizontal angle of 90° and the test is continued for a further 5 min.
The maximum acceptable radius of the oscillating tube is 1 600 mm.
The water pressure is adjusted to give the specified delivery rate. The pressure to achieve this delivery rate will be in the range of 50 kPa to 150 kPa. It should be kept constant during the test.
The test duration is 1 min/m 2 of the calculated surface area of the enclosure (excluding any mounting surface), with a minimum duration of 5 min.
IPX4:
The oscillating tube has spray holes over the whole 1 80” of the semicircle. The total flow rate is adjusted as specified in table 9 and is measured with a flow meter.
The tube is caused to oscillate through an angle of almost 360°, 180° on either side of the vertical, the time for one complete oscillation (2 × 360°) being about 12 s.
The duration of the test is 10 min.
