IEC60529 Figure 5 Brass Spray Nozzle Hand-Held Device for IP Rating Testing

1. Introduction

The spray nozzle hand-held device is designed according to IEC60529 figure 5, it is it is apply to verify the protection against spraying water (IPX3) and splashing water (IPX4) for large size sample. The hand-held device is consisted by spray nozzle, moving shield, counterweight, hose and pressure gauge. The spray nozzle is made of brass and has 121 holes with diameter 0.5mm (1 hole at center, 1 inner circles of 12 holes at 30⁰ pitch, 4 outer circles of 24 holes at 15⁰pitch). The moving shield is made of aluminum, the counterbalanced shield is in place for IPX3 test, the water pressure is adjusted to give the specified delivery rate, the pressure to achieve this delivery rate will be in the range of 50kPa to 150kPa, and it should be kept constant during the test, the test duration is 1min/m² of the calculated surface of the enclosure and with a minimum duration of 5 min. For IPX4 test, the counterbalanced shield is removed from the spray nozzle and the enclosure is sprayed from all practicable directions, the rate of water flow and the spraying time per unit area are same as IPX3 test.
