Table 18. Performance Criteria
Level
Description
A
The apparatus continues to operate as intended. No degradation of performance.
B
The apparatus continues to operate as intended. No degradation of performance beyond spec
limits.
C
Temporary loss of function is allowed provided that the function is self-recoverable or can be
restored by the operation of the controls.
