Re: [PSES] Was there ever a comparison between IEC 60950-1 and IEC 62368-1 (current edition preferable)? And any rationale for any of the changes

2017-12-05 Thread IBM Ken 
Hi Leo!

ECMA released a Technical Report (TR-106) in February 2013, so be
forewarned that it only compares IEC60950-1, 2nd ed (2005) to the *1st*
(2010) edition of 62368-1.  A significant number of clauses were moved or
renumbered between 1st and 2nd edition (enough that it made it difficult to
use TR-106 to compare 60950-1 with 62368-1, 2nd edition).  I made some
cross-referencing notes for internal use, but even with that, it was fiddly
to use.   I don't know of anything that compares 60950-1 to the current
(2nd) edition or the upcoming 3rd edition.

Your favorite NRTL or test house might have something by way of training
material that could help.

-Ken

Subject: [PSES] Was there ever a comparison between IEC 60950-1 and IEC 62368-1 
(current edition preferable)? And any rationale for any of the changes

I am in IEC SC62A (60601-1 series of standards - Medical electrical equipment & 
systems) meetings this week and we are trying to id the differences between 
these 2 standards so we can figure out how to integrate IEC 62368-1 into IEC 
60601-1, 3rd ed. + A2, if we have the time and agreement with the National 
Committees is to be determined. We are working on A2 currently (at CD1 stage) 
and initially we decided not to include IEC 62368-1 in the A2 but wait for 4th 
ed. but that likely may be too late for power supplies as 60950 is ending in a 
couple years for at least EU.
