Just a small, trivial detail ....
When equipment 1s teated for use in "wet" locations, a 'rain test' is performed.
While there are several such industry-wide tests, they differ in detail and language only, and effect essentially the same conditions.
Water enters a pan. In the pan are holes. Into the holes are placed nails. This results in the water forming drops, that fall with the force of gravity.
A fan is used to angle the 'rain' approximately 15 degrees from the vertical.
The samples are tested ... exposed to the 'rain' for the required time .... then opened up, and checked for 'excessive' water entry.
Depending upon the equipment, actual operation may not be required.
Because of this "15 degree" rain, nearly anything set back at all, or angled down in the slightest, is almost a slam-dunk to pass the test.
This is not to be confused with other tests that may employ hoses, or greater angles.
