ISO 14520-5:2016 covers the design of systems operating at nominal pressures of: 34.5 bar 42 bar 50 bar Propellant: Nitrogen is used as the pressurizing agent.

Part of the broader ISO 14520 series, ISO 14520-5 focuses specifically on the chemical agent FK-5-1-12 (often recognized by the trade name Novec™ 1230). This standard outlines the requirements for designing, installing, and maintaining fire protection systems in occupied and unoccupied areas.

Engineers and designers reference the ISO 14520-5 document for exact mathematical formulas and physical tables required to calculate the correct agent quantity for a total flooding application. 1. Physical Properties Table

Because HFC 227ea decomposes at high temperatures (above 400°C) into hydrogen fluoride (HF) and carbonyl fluoride (COF2), the standard mandates:

This section covers:

: Explicitly details the calculation equations for agent mass, fill density, and nitrogen superpressurization.

The document mandates the minimum percentage of gas required in the air to extinguish different classes of fire:

Because FK-5-1-12 is a liquid at room temperature with low vapor pressure, it requires an inert gas (usually nitrogen) to pressurize the cylinder. This ensures the fluid drives through the piping network effectively. ISO 14520-5 outlines the standard superpressurization levels: (with nitrogen) 42 bar (with nitrogen) 50 bar (with nitrogen) 3. Safety and Toxicity Limits

To provide designers, installers, and inspectors with the necessary data to design safe and effective clean agent systems.

A non-negotiable priority of ISO 14520-5 is the . The standard stipulates acceptable exposure limits to the agent and its decomposition products, which can form when the agent interacts with a fire. These guidelines are critical for establishing safe egress times and system configuration.
