Couldn't we just go to the front of the UL1950/60950 
standard and agree that a "safety critical part or device 
or circuit or construction" is simply something used 

"... 
to prevent injury or damage due to:  
- Electric shock hazard 
- Energy hazards 
- Fire hazard 
- Mechanical hazard 
- Heat hazard 
- Radiation hazard 
- Chemical hazard
...." 

Regards, Doug McKean
