Why am I seeing passing results on a nozzle when I use a temp of 0 but with I use a temp of +1 or -1 it fails? I agree that the nozzles should fail at -1 and +1 but I am missing something for why it is not failing for the zero temp.

Ambient: 70 F

-1 F: Fail
0 F: Pass
1 F: Fail

Operating Load Case: W+T+P
