IP ratings, which zones!

[ashm]

hello and thanks to all that answer,
Just wondered if anyone can explain the IP ratings for lights, I know it relates to the safety requirments in a bathroom, but does each IP rating relate directly to a specific Zone. if so which relates to which.
Thanks

just found this, helps but nothing about zones.

IP = Ingress Protection.

You write it IP xy or IP xyz, where:

x = rating against ingress by solid objects (1 being a hand, 6 being totally dustproof)
y = rating against ingress by liquids (1 being protection against vertical rain, 8 being totally waterproof down to depths below 1m)
z = rating against impact (1 being a gentle knock, 9 being a whack)

If you see a 0, that means there is no rating against that attribute.

In these forums you will see a 2 digit IP rating, as impact isn't really a consideration in domestic wiring (unless you like to go mental with a hammer at your CU )
