Bomb Firing
Once the initial equilibrium is confirmed, the con-
troller initiates the firing sequence. There are no
changes to the circulation pattern, as shown in
Figure 3-4, from the pre-period through the bomb
firing and post-period. A warning of short beeps is
sounded indicating the bomb is about to be fired.
Post-Period
A minimal temperature rise will confirm that the
sample has ignited. After this verification, the post-
period begins. See Figure 3-4.
1. The controller monitors the temperature rise
and determines the final temperature rise by
either the dynamic or equilibrium criteria as
established by the user.
2. Once the final temperature rise is determined,
it is recorded with the test results.
