Yes. The LEED standard references test procedures from the ASTM E779-10 standard, so we have included the "LEED Permeability" result (in units of in2/100 ft2) in the user interface of the ASTM standard.
In other words:
- Download FanTestic, if you haven't already
- Go to Choose Tools-->Options section of the software, and select the standard "ASTM E-779-10"
- Click File--> New Test
- Perform your Door Fan test, and once you have all your data, and it will calculate a "LEED Permeability" result for you at the bottom of your test set.

Uninstalling FanTestic will NOT remove any of your test files or reports, it will only uninstall the program files.
It is generally a good practice to regularly back your test and report data to a different location.
Uninstalling FanTestic will also NOT uninstall the DM-2 USB driver. You should still be able to see it listed as installed in your Control Panel after you restart the computer.

You need to consider that there is a fundamental issue of uncertainty with using 4 Pa as a reference pressure. Just imagine, if there is even a 1 Pa fluctuation, due to so many possible sources that can cause pressure fluctuations as you know, the pressure measurement already has an uncertainty of +/- 25% error. Consider that for almost all airtightness testing standards across the world, the reference pressure for Flow results are either 50 Pa or 75 Pa.

How and when should I compensate for leakage around the door panel?
Modular Panels are designed to be placed into doors that are not well sealed. The panel leakage for the Modular Panel is about 14 square inches compared to about 3 square inches for the Aluminum Frame and Cloth and around 1 square inch of leakage for the upgraded Aluminum Frame with snap together corners. These three panels represent three typical doorways:
- Poorly weather-stripped which would have an approximate 1/16 inch gap which equals about 14 square inches leakage;
- A well weather-stripped and adjusted door would be around 3 square inches or leakage;
- A super tight door could be as tight as 1 square inch of leakage and can even have less.
One rule of thumb is that all standards

Currently none of the standards require independent or 3rd party testing. Much of this responsibility is given to the AHJ who is supposed to ensure all codes are followed. The reality is few AHJ completely understand the standards and are easily persuaded by the installer that everything has been done correctly. Increasingly the role of ensuring the building is up to spec has been taken on by commissioning agents. Their job is to ensure that the entire building is up to spec and that includes the suppression system. The commissioning agent is hired by the owner to ensure the owner is getting what they paid for, which includes compliance with all building and NFPA codes.
We often get questions from AHJ or commissioning agents who are concerned about how the enclosure test was performed, and there is good reason for this. Half the enclosure integrity tests done in Europe and 60% of those performed in the US do NOT include a peak pressure evaluation. Peak pressure evaluation

Our manufacturer's recommendation for calibration is as follows:
- Retrotec fans: Every 5 years.
- DM-2 Manometer: Every 2 years or if the Manometer fails a field check.
- DM32 / DM32 WiFi Manometer: Every 5 years or if the Manometer fails a field check.
Please review the DM32 and DM-2 Manuals on how to perform a field check.
This only covers our manufacturer recommendation. The energy standards (EN13829, ASTM, ATTMA, USACE, etc...) that you are using for test results may have different calibration intervals. Please consult the energy standards for the specific equipment calibration intervals.

Retrotec recommends you take the maximum number of test points to decrease the uncertainty in your test.
Yes, you can change this default and take only 5 readings according to the Standard but your uncertainty will often be too high and you might have to retest. Next, you might retest and find the result differs from the previous test by 10% or more making you lose confidence in the results. Retrotec defaults that include taking 10 test points and longer baselines will optimize your tests and give better results.
You might save a few minutes by testing to the minimum allowed by the Standards but in the long run, your test results will be poor. Officials look at high uncertainties and poor repeatabilities between your tests and wrongly conclude your equipment is faulty but the truth is that your test method is faulty. Please use our defaults as practical minimums and if anything take your tests over a longer time rather than shorter and your results will

I see online on the support page, or when I use the File menu item 'Check for updates', that there is a new version for the software, but when I launch my existing version of the software, I do not get the message that there is a new version.
This problem is often caused by anti-virus programs. In particular we have found that using Internet Explorer and a virus protection program from Microsoft called 'Windows Smartscreen' can cause the problem, but others will likely also interfere with the download.
Disable your anti-virus program, uninstall the earlier version and download and install the new version from the website:

If you are using FanTestic with a DM-2 and have to use the ADMIN shortcut to be able to control your DM-2, you will newer get notification of the need to update. To do the update, you
