I have always viewed the Safety Critical Components List (SCCL) as kind of like
a Cheat Sheet or Road Map to a safety inspection. As probably most Safety
Inspectors, I wouldn't even think about starting a safety evaluation without
the SCCL up front
.

All makes perfect sense.
In the case of a project I have now which
to including the C/C tables
found in the safety and EMC reports.

Do not know, but in principle should be ok. The 'flagged' components in the
company's document control system is typically a superset of the C/C
file?

Hi Dave:
There are no standard definitions for critical
components
Dave,
You pretty well outlined the main concerns for safety critical components.
Identifying all the hazards and risks is the first step and then identifying
the components relied upon to mitigate those issues is next. As product testing
proceeds there may be additional components added. I
