Introduction to Enclosure Integrity testing for Peak Pressure & Hold Time
Key Learning Objectives
Understanding the Two Key Metrics
Peak Pressure: The maximum air pressure (or force per unit area) an enclosure must withstand during agent discharge.
Hold Time: The duration the enclosure must maintain at least its design concentration level, accounting for natural leakage.
Both metrics are essential for safe, compliant clean-agent fire suppression systems
Door-Fan Based Testing
A specialized blower (door-fan) setup pressurizes the room to simulate discharge events.
Data gathered—flows versus pressure—is fed into calculations based on Annex C of NFPA 2001 or ISO 14520 to model performance.
FanTestic Integrity Software
Demonstrates connecting door fans and gauges to software for automated control.
Shows how to run tests, capture peak-pressure levels, hold-time decay, and generate compliance-focused reports.
Why It Matters
Safety & Compliance: Ensures enclosures can handle discharge pressure without structural failure and maintain agent levels to extinguish fires.
Automated & Accurate: FanTestic Integrity simplifies data collection, analysis, and reporting to approved standards.
Multi-Standard Compatibility: Supports NFPA 2001, ISO 14520, EN, AS, FIA, and VdS protocols.
