How to do IPX5 IPX6 testing with jet test nozzles?

Conform to IEC60529 IPX5, test for second characteristic numeral 5 with the 6.3mm nozzle:

The test is made by spraying the enclosure from all practicable directions with a stream of water from a standard test nozzle as shown in figure 6.

The condition to be observed are as follows:

Internal diameter of the nozzle : 6.3mm
Delivery rate: 12.5 l/min ±5%
Water pressure:to be adjusted to achieve the specified delivery rate
Core of the substantial stream: circle of approximately 40mm diameter at 2.5 m distance from nozzle
Test duration per square metre of enclosure surface area likely to be sprayed: 1 min
Minimum test duration : 3 min
Distance from nozzle to enclosure surface : between 2.5 m and 3 m.

Conform to IEC60529 IPX6, test for second characteristic numeral 6 with the 12.5mm nozzle:

The test is made by spraying the enclosure from all practicable directions with a stream of water from a standard test nozzle as shown in figure 6.

The condition to be observed are as follows:

Internal diameter of the nozzle : 12.5mm
Delivery rate: 100 l/min ±5%
Water pressure:to be adjusted to achieve the specified delivery rate
Core of the substantial stream: circle of approximately 120mm diameter at 2.5 m distance from nozzle
Test duration per square metre of enclosure surface area likely to be sprayed: 1 min
Minimum test duration : 3 min
Distance from nozzle to enclosure surface : between 2.5 m and 3 m.
