  1. Refer to Emission Spot Diameter vs. Distance in Engineering Data (Reference Value) on Data Sheet for details. 

       2. IP69K Degree of Protection Specification 

          IP69K is a protection standard against high temperature and high-pressure water defined in the German standard DIN 40050, Part    9. The test piece is sprayed with water at 80°C at a water pressure of 80 to 100 BAR using a specified nozzle shape at a rate of 14 to 16 liters/min.
 The distance between the test piece and nozzle is 10 to 15 cm, and water is sprayed     horizontally for 30 seconds each at 0°, 30°,    60°, and 90° while rotating the test piece on a   horizontal plane.
