Detailed information on these technical aspects can be provided upon request. ISO 14520-5:2016 - Gaseous fire-extinguishing systems
To verify that the fire suppression system is designed and installed correctly for insurance and safety compliance. 5. Difference Between ISO 14520-5 and Other Standards
FK-5-1-12 is highly regarded for its low environmental impact, which is explicitly quantified in the ISO documentation. 0 Global Warming Potential (GWP): Less than 1 Atmospheric Lifetime: Approximately 5 days
This part of the ISO 14520 series provides technical data specifically for the agent, including: iso 14520-5 pdf
Since ISO standards are adopted globally, you can buy from your local representative:
If the concentration calculated is too low, the system will fail to suppress the fire. Conversely, if it is calculated incorrectly on the high side, it could unnecessarily narrow the safety margin for occupants or cause structural over-pressurization during discharge. Hydraulic Flow Calculations
The standard sets a minimum design concentration, typically around 5.3% to 5.6% by volume, depending on the specific safety factors applied. Detailed information on these technical aspects can be
No. The PDF provides the formulas and constants. However, many commercial fire system manufacturers (e.g., Kidde, Fike, Siemens) embed ISO 14520-5 calculations into their proprietary design software (e.g., FIKESystem, KSS). You must still verify their outputs against the PDF tables.
ISO 14520-5 defines the minimum extinguishing concentration (MEC) verified through standard laboratory testing (such as cup burner tests). It then establishes the mandatory , which includes a safety factor (typically an additional 30% over the MEC).
ISO 14520-5 is part of a larger series of standards titled "Gaseous fire-extinguishing systems — Physical properties and system design." While the general requirements for these systems are covered in Part 1, each subsequent part focuses on a specific extinguishing agent. Difference Between ISO 14520-5 and Other Standards FK-5-1-12
The ISO 14520-5 standard outlines the strict physical properties that the FK-5-1-12 extinguishing agent must meet to ensure performance.
Minimum purity levels to ensure effective suppression.
