Hi Doug,
This looks like a very good summary and mentions a few of the things I was,
in my poor attempt, trying to point out. One of my concerns about RA, and
FMEA in particular, is that this method does have a lot of numeric
computation for what is essentially a qualitative process. As such, it
“Outdoor “ …IP … will it withstand the “ flash rain, or severe rainfall
leading to flooding…

I generally see outdoor telecoms enclosures specified and tested to IP66 or
IP67, or NEMA 4X, but EN 60950-22:2006 and EN 62368-1:2020 only required IP54
to provide PD2 environment.

Hi Rich,
I have to admit that I’ve been thinking about your reply all weekend.
As you know, I teach machinery risk assessment and consult in this area
regularly. I want to stipulate that there are some significant issues with risk
assessment the way it is most commonly applied in industry, see
I agree wit Ted Eckert on this. Generally for outdoor use you’d need IP65 at
least.

I have seen large industrial UPSs or battery chargers that have IP22 roofs.
The roofs cover over fan grilles on the top, leaving approx. 50 mm of air for
ventilation.
Though they may be used to stop water drips or condensation coming off pipes,
they are mostly intended to keep cut stranded
Its been a while since I looked - but I think the standards typically lists
the changes and differences. Or has that changed?

Hello Rich
I am somewhat alarmed by a paragraph in your email!! In it you indicated
that:
"When I evaluate a product, I look for the physical energy sources, *and
then determine if the energy sources are hazardous or no*t. Unlike Risk
Assessment, this is easy and repeatable and not subjective.
Hi Brian,
The IP ratings apply to continuous situations unless stated otherwise. So IPX2
means that water drops can be continuously falling at 3mm/min when the EUT is
tilted up to 15°. The test lasts for 2.5 minutes per side, but the environment
is considered continuous. For our machinery
Hi Brian,
It is reasonable to state that an IP22 device is not intended for outdoor use
or where exposed to water. A much higher IP rating would be required for
reliable operation outdoors, and most people who purchase outdoor equipment
would not accept a product with only an IP22 rating.
Ted
An IP code of IPx2 implies the enclosure protects against the ingress of
water drops at 15° tilt. Now, most PC enclosures protect the electronics
from occasional exposure to water drops, but it is not designed to be
exposed to water drops continuously. So can you rate an electronic device
IP22,
