Assumptions and warnings While FanTestic Integrity software may identify clean agent peak pressure and hold time risks, use of this software does not in any way guarantee the elimination of those risks. Enclosure Integrity (hold time) The enclosure was tested in compliance with NFPA 2001 (2012 Edition) Annex C Enclosure Integrity Procedure. These tests only address potential failures in maintaining extinguishing agent concentration due to excessive enclosure leakage. The following assumptions were made: • The initial extinguishing agent concentration as indicated in the test report will be achieved. • Ductwork connected to air -handling systems that are outside this enclosure will be either isolated with dampers or will be shut down during the hold time. • If air handlers are used to provide continuous mixing, they will be dedicated to this enclosure and will not create significant flows across the enclosure boundaries. • An adequate return path for the air flow was provided during the enclosure integrity door fan tests. • All intentional openings will be sealed during the enclosure leakage for hold time tests. • There are NO fans that continue running during the hold time or heat sources that will produce enough air circulation to cause a 'continuous mixing' condition within the entire enclosure. • All other non -integrity tests, as outlined in the NFPA standard, will be satisfactorily completed. Enclosure Integrity (peak pressure) Enclosure integrity tests and calculations were performed to determine that the enclosure has adequate venting to provide peak pressure relief as required by NFPA 2001 (2012 Edition) section 5. Calculations for peak pressure were performed using equations from the Fire Suppression Systems Association (FSSA) "Pressure Relief Vent Guide". The following assumptions were made: • All intentional openings will be set to the operating condition expected during the agent discharge for positive peak pressure relief when enclosure leakage is tested for positive vent area. • In addition, for halocarbons only, all intentional openings will be set to the operating condition expected during the agent discharge for negative peak pressure relief when enclosure leakage is tested for negative vent area. • Adequate air flow was provided along a path leading to outdoors for the test fan but the doors surrounding the enclosure were set in the position that provide the lowest air flow required to establish the required test pressures. • Design temperature inside the tested enclosure during discharge is 70.0'F.
