Difference between "Board-level" and "System-level"

As said in title, I’m hoping that someone can provide some detail on what these terms mean.

If the context matters, I came across these terms in the Jetson Xavier Series System-on-Module Data Sheet, in the first two rows of table 16 on page 83. See image attached.

Any help would be appreciated.


Board-level is PCBA qualification test, checking the quality of PCBA. It’s based on JEDEC standard.

System-level is to test the whole system. It’s more usage condition-oriented, simulating real usage scenario. It’s based on IEC or ISO standards. system-level is the whole system including cooling fans, power adapter, chassis, housing, etc.
