E3FA/E3RA/E3FB/E3RB
Radial type ((E3RA/E3RB))
* IP69K Degree of Protection Specifications
IP69K is a protection specification stipulated by DIN 40050 Part 9 of the German standards.
The test item is sprayed with 80°C water from a nozzle of a specified shape at a water pressure of 80 to 100 bar. The amount of water
is 14 to 16 liters per minute.
The distance between the test item and the nozzle is 10 to 15 cm. The water is discharged at angles of 0°, 30°, 60°, and 90° from
the horizontal plane for 30 seconds at each angle while the test item is rotated horizontally.
