How long is the spray testing done on the IP69K?

Test time is 2 minutes.  IP stands for Ingress Protection. The first digit specifies the protection against solids and the second number specifies the protection against liquids; the higher the number, the greater the level of protection. IP69K is a protection provision of high temperature and pressured water which prescribed by Germany standard DIN 40050 PART9. The test specifies a spray nozzle that is fed with 80°C (176°F) water at 80 to 100 bar (1160 to 1450 PSI) and a flow rate of 14 to 16 L/min (3.7 to 4.2 gal/min). The nozzle is held 10 to 15 cm (4 to 6 inches) from the tested device at angles of 0°, 30°, 60° and 90° for 30 seconds each. The test device sits on a turntable that rotates at 5 RPM.
