Cabinet-type Gas Extinguishing System Performance Requirements and Test Methods
Introduction
A cabinet-type gas extinguishing system, also known as a total flooding system, is a fire protection system that is effective for the protection of people, environment and property. A cabinet-type gas extinguishing system utilizes inert gas, such as argon, nitrogen, carbon dioxide or a halocarbon blend as the extinguishing medium. This document was created to define performance requirements, test methods and criteria related to cabinet-type gas extinguishing systems.
Performance Requirements
A. System Components
Cabinet-type gas extinguishing systems must include the following components:
1. An automatic detection and actuation system, which must include the fire and non-fire initiation device(s) and accompanying control panel and software.
2. A storage cylinder(s) filled with an appropriate extinguishing medium.
3. A discharge device to propel the extinguishing medium into the protected space.
4. A one-way valve to prevent counter-flow of the extinguishing medium from the protected space.
B. Durability
System components must have a minimum life expectancy of 5 years.
C. Safety
System components must be designed and installed in accordance with applicable laws, regulations, codes and standards.
D. Operational Performance
The system must be capable of extinguishing a fire in a minimum time of 1 minute from the initiation of the fire.
Test Methods
A. Performance Tests
Performance tests must be conducted to evaluate the operational performance of the system. Tests must be conducted in a laboratory or simulated environment that is representative of the intended use of the system. The tests must be designed to evaluate the following parameters:
1. Operational performance.
2. Durability.
3. Safety.
B. Durability Tests
Durability tests must be conducted to assess the long-term performance of the system. The tests must be designed to evaluate the following parameters:
1. Structural integrity.
2. Wear and tear.
3. Corrosion resistance.
4. Resistance to extreme temperature and humidity.
C. Safety Tests
Safety tests must be conducted to evaluate the structural integrity, usability and reliability of the system components. The tests must be designed to evaluate the following parameters:
1. Resistance to water and vapors.
2. Resistance to mechanical shock and vibration.
3. Compliance with applicable safety standards.
4. Accuracy of system activation and detection.
5. Resistance to external electric and magnetic fields.
Conclusion
The performance requirements, test methods and criteria provided in this document are intended to ensure that cabinet-type gas extinguishing systems meet the requirements of their intended use. The performance requirements and test methods outlined in this document must be adhered to in order to ensure the reliability and effectiveness of these systems.
