ISO updates standards periodically. The current version (2016) includes critical revisions regarding design altitude corrections and discharge time limits. Older, freely circulating PDFs often reference withdrawn or hazardous practices.

ISO 14520-5 cannot be used alone. It must be used in conjunction with , titled Gaseous fire‑extinguishing systems — Physical properties and system design — Part 1: General requirements . While ISO 14520-5 provides the agent-specific data, ISO 14520-1 provides the overarching rules for design, installation, testing, and maintenance common to all gaseous systems. Together, they form a complete framework for a compliant system. : Applicable to systems using nitrogen propellant at
