PSNet'ers,
M Loerzner is correct IEC/TC 108 has approved 108/325/FDIS as IEC
62368-1. This is the long awaited Hazard Based Safety Standard, a
significant change in the approach to developing the safety requirements.
It will be a replacement for both IEC 60950 and IEC 60065 after the
transition period. The transition period will be determined by the
implementation process (within the IEC plus development of the EN for Europe
and the NA CSA/UL document, etc) but it is the desire of TC 108 that it be a
longer than normal period of time.
The purpose of starting this project was to bring together the
requirement for commercial and consumer electronic equipment which use the
same technology. Note that some changes have already been implemented in
both 60950 and 60065 to bring some of the requirements together but these
standards are written in somewhat different ways and further integration is
difficult.
In my opinion, this standard more comprehensively covers the hazards
that can be found in electronic equipment. Some have expressed that there
is both opportunity and danger in this change. The same feelings were there
when IEC 950 replaced the earlier requirements; everyone involved survived
that change.
TC108 has set out on a unique path to capture the rationale for much
of the requirements to aid future members of the committee understand the
details of the development of these requirements; this will be available
>from the IEC along with the standard and be useful to others in
understanding some of the thinking.
I have high regard for the chairman & secretary & Hazard Based TA,
the team leaders and many others who worked thru the details to develop this
new standard.
I have found it a privilege to serve as part of the TC108 group
writing this new standard and have high hopes for its success.
br, Pete
