How to use spray nozzle test devices

According to requirements of IEC60529 IPX3, conditions when using the IP Test Spary Nozzle as in figure 5 :
The counterbalanced shield is in place for this 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 50 kPa to 150 kPa. It should be kept constant during the test.
The test duration is 1 min/m²of the calculated surface area of the enclosure(excluding any mounted surface ), with minimum duration of 5 min. 
 
If for IEC60529 IPX4 testing, conditions when using the IP Test Spary Nozzle as in figure 5 :
The counterbalanced shield is removed from the spray nozzle and the enclosure is sprayed from all practicable directions. 
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/m² of the calculated surface area of the enclosure(excluding any mounted surface ), with minimum duration of 5 min. 
 
Our IP Test Spary Nozzle ZLT-JL1 meets with above requirements.
