Level
Description
A
The apparatus continues to operate as intended. No degradation of performance.
B
The apparatus shall continue to operate as intended. No degradation of performance beyond spec limits.
C
Temporary loss of function is allowed provided the function is self-recoverable or can be restored by the operation of the
controls.
