For checking the protection against water with spray nozzle of 0,4 mm bore are used to prove the degrees of protection for the second characteristic numerals 3 and 4 “Protection against Spraying Water” resp. “Protection against splashing Water”.
The oscillating tube test is one of several methods used to test the water protection capabilities of enclosures for electronic items that are expected to be exposed to rain or water spray.
This test is used to meet the requirements of IPX3 and IPX4 in IEC 60529. In the test described in IPX3 and IPX4 with an oscillating tube, the specimen is placed in the center point of the semicircle defined by the oscillating tube. It is then subjected to a spray of water at a defined pressure to test for leakage.
The oscillating tube will have spray holes over 120° of the tube for IPX3 and over the full 180° for IPX4. In IPX3 the tube will oscillate to 60° either side of the vertical. For IPX4 the tube travels through an angle of almost 340°. The specimen needs to be placed within 200mm of the tube. For this reason different size tubes are needed to test different size specimens.
