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.

Thanks all.

For the situation I am looking at, I suspect I'll go with the IP69 fittings.

I'm still none the wiser however regarding the use of higher than ambient temperature water at IP65/66 flow rates. Does the testing of the product using specimen/ambient temperature water mean that the certification of the product as IP65/66 is temperature dependent? If someone then washed down the product with 40ºC water and it failed, does that void any warranty claim?
