Whether you are designing a server room, a marine engine compartment, or a valuable archive, this article explains everything you need to know about the standard, its contents, where to find legal copies, and how to apply its requirements.
). It is heavily favored in modern fire engineering because it acts as a "clean agent," leaving absolutely no conductive or corrosive residue upon discharge. Because HFC 227ea decomposes at high temperatures (above
ISO 14520-5 is specifically applicable to , meaning systems designed to discharge agent to achieve a uniform concentration throughout an enclosed space. It covers systems that operate at nominal container pressures of 25 bar, 34.5 bar, 42 bar, and 50 bar , using nitrogen as the propellant.

HFC-227ea is a colorless, odorless, liquefied compressed gas. The standard specifies its exact chemical formula (
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.
