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

pww235 over 5 years ago

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.

2400, that was really interesting. I suppose it demonstrates just how unaware we can be of the actual tests behind products. There is a similar but perhaps more critical issue in the fire safety side of things used in general construction and indeed in electrical installations where the testing regime is sometimes far less robust than one might imagine.
