Full title and description

ISO 14520-3:2000 — Gaseous fire-extinguishing systems — Physical properties and system design — Part 3: Halocarbon agents

Abstract

This part of ISO 14520 specifies physical properties, storage, handling and aspects of system design for halocarbon gaseous fire-extinguishing agents used in total flooding systems. It provides data and guidance needed by designers and manufacturers to select, store and apply halocarbon agents safely and effectively in fire suppression installations.

General information

• Status: Published standard (2000)
• Publication date: 2000
• Publisher: International Organization for Standardization (ISO)
• ICS / categories: 13.220 (Firefighting) / Gaseous fire-extinguishing systems
• Edition / version: Edition 1 (2000)
• Number of pages: Approximately 20–40 pages (typical for ISO parts; exact page count may vary by print)

Scope

ISO 14520-3:2000 defines the physical and chemical properties, storage conditions and handling recommendations for halocarbon agents used in gaseous total flooding fire-extinguishing systems. The standard addresses characteristics such as boiling point, vapor pressure, density, toxicity limits, thermal stability, compatibility with materials and typical system design parameters relevant to enclosures protected by halocarbon agents.

Key topics and requirements

• Specification of key physical properties of halocarbon agents (density, vapor pressure, boiling and freezing points).
• Guidance on storage and handling: container requirements, temperature limits and transport considerations.
• Information to support system design: agent concentration for extinguishment, nozzle and discharge characteristics, and storage volume calculations.
• Compatibility with common materials and recommendations to avoid corrosion or material degradation.
• Safety considerations, including toxicity guidance, exposure limits and precautions for personnel during and after discharge.
• Testing and verification notes for agent quality and system performance.

Typical use and users

Used by system designers, fire protection engineers, manufacturers of gaseous suppression systems, installation and maintenance contractors, facility managers of critical facilities (data centers, telecom exchanges, museums, power plants) and regulatory authorities. It supports selection and safe deployment of halocarbon agents for total flooding fire suppression.
