Performance standard A：During and after the test the equipment shall be able to continue operation as
specified.
Performance standard B：The equipment shall be able to continue operation as specified after the test.
However, performance degradation during testing is allowed.
Performance standard C：Temporary loss of function is allowed, but the function can be self-healing or
can be recovered by operation of the control device.
