Evening all.
Bit of a head scratcher:
IP65 / IP66 testing must use water that it within 5K of the specimen under test.
IP69 testing uses water at 80ºC (+/- 5ºC).
I have a process area that will be subject to jet washing with hot water fed from the domestic system and so will be somewhere in the region of 40ºC - 60ºC.
The luminaires within the space shall be IP66 for the water flow rates but should they also be IP69 rated to account for the hot water?
Appreciate any thoughts.
