In our experience:
Argentina, Australia and China (PRC) cords are mutually exclusive and cannot be
bundled together.
Brazil no longer accepts any cord that looks like a US NEMA 5-15 plug.
India and South Africa cords are mutually exclusive unless you can get one that
carries certifications
the "mutually

I am writing today seeking comments on UK Plugs BS 1363 as the standard plug
and cordage to ask if any are also known "mutually exclusive" issues.
For example between United Kingdom, Saudi Arabia, Singapore?
Thank you in advance,

Steve,
That is the way we certify our products, which are to IEC/EN/UL 62368-1.
The alternative is to have the power supply re-tested and listed as part of
your product, with all the critical components added to your CCL and the
applicable fault testing of the power supply repeated in your

Gary,
It may depend on which standard you are using to certify your product. Here are
3 references from an investigation I performed in 2014:
1. UL 60950-1, Annex NAE, Clause 3.2.5, Cord-connected equipment - "The
length of a power supply cord shall not exceed 4.5 m (14.76 ft)" [NEC 400.8,

Rich,
We have always preferred the AC test in manufacturing, as we felt it was a
better test. However some technical issues, not safety related, have come
up that caused one of the development teams to request investigating using
the DC test for the routine manufacturing test.
Thanks,
Gregory
All,
In reviewing IEC 62368-1 Clause 5.4.9.1 the test procedure states about
halfway down the page:
The insulation is subjected to the highest test voltage as follows:
- by applying an a.c. voltage of substantially sine-wave form having a
frequency of 50 Hz or 60 Hz; or
- by applying a d.c.

Brian, Mike,
Thank you, you have nailed the chief objections we have been struggling
with as well. Our attempt to align usage across the business has received
the strongest objections from the code guys because Microsoft does it. We
will look at the MSDN site as well.

Rich,
Thanks for forcing my brain into another frame of mind. I had not thought
of it in exactly that way until I read your comment. The statements we are
discussing are either those prescribed by the applicable standard, or more
often, the CYA type statements we all include in our users guides
Looking for input from the group.
The definition of the signal words per ISO 3864-2 and ANSI Z535.6 are:
DANGER - signal word used to indicate an imminently hazardous situation
which, if not avoided, will result in death or serious injury
WARNING - signal word used to indicate a potentially
Charlie,
The spacing between the pads where the SMT resistor is mounted may be so
small that the resistor failure mode doesn't matter. The creepage distance
itself may require consideration of a short between the pads as a valid
single fault condition..

Mike,
For the 5000 m requirement, you need to multiply the Clearance requirements
by 1.48 per Table A.2 of GB/T 16935.1 (equivalent to IEC 60664-1) to
correct for the altitude change from 2000 m to 5000 m. This will also drive
your Creepage requirements to match the Clearance values as Creepage
We spec an operating altitude to 3000 m (10,000 feet. sometimes 9800 or
9500 ft, depends on who did the math). We have moved most of our power
supplies to 5000 m in the CQC report for the supply in order to allow us to
claim compliance with the safety requirement to 5000 m in China. We have
