RE: UPAMD goals - life expectancy
IEEE Standards, and any other standard working under the ANSI (American
National Standards Institute) rules, must be revisited every 5 years, they
may be reaffirmed, revised, or withdrawn by a vote of a sponsor balloting
body. I will here assume that the UPAMD will be both reaffirmed, or
revised, multiple times. At this point, with an eye to enhancing
capabilities later, the communications will be the area to keep flexible.
USB is an example of having backward compatible standards. All devices
still support, in some way, the 1.5MHz version. This could be a model.
I really look forward to buying an UPAMD power system with the expectations
of using it for much more than 10 years.

If I am reading this right, you agreeing with 10 year life meaning "to
become obsolete".
I don't think we should try to spec 10 years life "as until breaks"
because it will make Conformity Verification a nightmare.

I don't think we should define MTBF; this is up to each manufacturer to
spec.
I think the original idea is that the standard requires a new affirm
every 5 years and we should expect that it last for at least 2 renewal
with major changes so much that it gets obsolete.

> a. Life expectancy of 10 years, hopefully more
Yes.
Maybe one question - "life expectancy" as MTBF, or as "to become
obsolete"?
