IP rated luminaires for jet wash with high temp. water?

pww235
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.

    temp is not the only factor, but also the strength of the jet.


    IP66 is 'jets of water' but only at approx 1 atmosphere pressure, and IP65 is 1/3 of that pressure.

    IP 69 is indeed hot but also at 100 atmosphere water pressure.

    It all rather depends on the strength of the jetwash, many are well above 1 atmosphere  IP 65/66 may not be quite enough if yours is one of these.


    IP69 ( or 69K in the German version of the standards  ) is common in places like aspects of food production that need more than just a light wash down.
