
“Calculated hold time (continuous mixing)” [min]
The Hold time for a Continuous Mixing “Test type”. For an Enclosure Integrity Test to pass
according to ISO 14520, this time must be at least 10 minutes, or greater than the
“Specified hold time” entered in the “Agent Info” section of FanTestic Integrity. This
number can be increased by sealing up leakages in the enclosure. For a description on
Continuous Mixing type systems, refer to section 3.3.1.

“Extended discharge rate“ [lb/min, kg/min]
The extended discharge rate that is required for the enclosure, which depends on how
much leakage is in the enclosure. For an Enclosure Integrity Test to pass, this number must
be greater than the existing Extended discharge rate, entered as the actual Extended
discharge rate (in the “Agent Info” section of FanTestic Integrity), designed for the system.
This number can be increased by sealing up leakages in the enclosure. For a description on
Extended discharge type systems, refer to section 3.3.1.
4 Analyse Venting and Peak Pressure
The last expanding tab in the user interface provides places to enter details about the venting and peak
pressure calculations based on the chosen formula (as described by FSSA, FIA or VdS, or NFPA12 for
CO2):
If you open the expander titled “Venting and Peak Pressure Analysis” by clicking on the down arrow to
the left, you will see:
