FanTestic Integrity

FanTestic Integrity software  calculates hold time calculation for Enclosure Integrity for users in the fire suppression market.

NFPA and ISO do not certify any equipment or software directly. They are simply a standards writing body who takes input from the industry.  In the case of hold time calculation and peak pressure evaluation the input from the industry was primarily from Colin Genge the CEO of Retrotec who wrote the original NFPA Enclosure Integrity Procedure for NFPA in 1984 and has been the only force in making changes to the Standards ever since.  As a result, Retrotec training certification is accepted across all equipment manufacturers, end users in over 60 countries.

Colin Genge is used as a resource by Siemens, Tyco, Kidde, Ansul, Chemetron, Janus, Fike and 3M. If there is a question about enclosure hold time or peak pressure, he is the one who answers it. 

Checking with Microsoft Windows Click Once  Installer information, the error message you are receiving tells us the following: 

"These are generic error messages that occur when the application cannot be started, and no other specific reason can be found. Frequently this means that the application is somehow corrupted during download, or that the ClickOnce store is corrupted."

So it would seem that some of the files did not download correctly or that your ClickOnce user store may be corrupted.

Go to your Control Panel and Uninstall FanTestic.  If you get a message box asking if you want to roll back to a previous state or to Uninstall, choose the Uninstall option.  Then restart your computer.  If there are any FanTestic shortcuts left on your desktop, you will need to delete them.

The leakage rate IS important because there is a direct correlation between leakage area and peak pressure.  If the leakage is small enough, every room will face destruction upon discharge. The reality is that most rooms are so leaky that the opposite is a problem. The agent typically leaks out so quickly that the enclosure doesn't pass the hold time requirements which means there is very little peak pressure which is why many systems do not require venting. For most FM200 systems there is a leakage range where the enclosure is tight enough to maintain sufficient hold time but not leaky enough to require vents. You'll only know if you're in that zone by performing a door fan test according to Annex C of NFPA 2001. ISO has a near identical Annex E.

Both Standards require a peak pressure evaluation to determine whether or not the enclosure will be damaged upon discharge. Unfortunately neither standard provides the peak pressure formula. Traditionally, manufacturers of inert systems

Why is there a reference pressure for EqLA results?
(Or Flow, Permeability, ACH results?)

The results are all referenced to a single pressure, the reference pressure.  The reference pressure is dictated by the standard with which the test is trying to comply.

Induced building pressure is directly proportional to airflow rate through a building, and EqLA is directly proportional to airflow rate; so that a higher induced building pressure would be a higher EqLA. Hence, there needs to be a reference pressure when referring to a leakage or flow result.

For the ASTM standard, the leakage result is required to be at a reference pressure of 50 Pa, whereas it is 75 Pa for the USACE standard. Reference pressure also applies to permeability (e.g. CFM/ft2) and air change (ACH) results.
