I am doing duct testing and use the DW/143 standard (UK).  FanTestic keeps telling me the test is not compliant, what am I doing wrong?

FanTestic checks that you have held the ducts at the test pressure for at least 900 seconds.  If you do not, the test will show as not compliant.  If you did a manual test and are entering the information into FanTestic, be sure to enter the time over which the test pressure was held.  If this is greater than 900 and your other test conditions are correct, the test will show compliant. 

Compliance means the test conditions comply with the stated requirements for a test  in DW/143.  Pass or fail means that the measured results are within the required level.
