IP66 NEMA 4

[drawoh]

I am working on a housing that must be weatherproof. It is mounted outside on top of an SUV.

I do not have a lot of room, so I am trying to eliminate some of the gaskets. My primary seam is between a cover and a base plate. The cover is installed from the top. There is a flat, machined surface that makes contact with the top of the base, also machined flat. This all is embedded in a fairly deep, accurate pocket, such that the machined contact faces are not very accessible to jets of water. The bottom of the cover and the bottom of the base plate are flush.

Does anyone have experience with testing stuff like this, or has anyone seen literature I can look for?

This is IP66/NEMA_4 stuff. It will not be submerged.

What type of literature are you looking for?

"Art without engineering is dreaming; Engineering without art is calculating."

Have you read faq731-376 to make the best use of these Forums?

MadMango,

That was a nice link. I have just printed it off.

I understand the standards. IP66 and NEMA_4 require the enclosure to survive fairly violent jets of water. What I am looking for is practical knowledge of what might actually survive this. I am trying to avoid using a gasket.

I am searching Amazon.com. I have found the book Seals and Sealing Handbook Fifth Edition, by Robert Flitney. Is anyone familiar with this? There are no reviews on the site.
