Full title and description

ISO 15779:2011 — Condensed aerosol fire extinguishing systems — Requirements and test methods for components and system design, installation and maintenance — General requirements. This international standard specifies requirements and test methods for components and provides recommendations for the design, installation, testing, maintenance and safety of condensed aerosol firefighting systems used in buildings, plants or other structures.

Abstract

ISO 15779:2011 covers total‑flooding condensed aerosol fire extinguishing systems that use electrically non‑conducting condensed aerosol extinguishants. It defines component test methods and performance characteristics, and gives guidance on system design, installation, testing and maintenance. Local (pre‑engineered) applications are excluded and must be separately tested and approved for specific uses.

Scope

Specifies requirements and test methods for components of condensed aerosol fire extinguishing systems and provides recommendations for design, installation, testing, maintenance and safety. The standard applies primarily to total‑flooding systems for buildings, plants and similar enclosed spaces using electrically non‑conducting condensed aerosol extinguishants for which performance validation data are available. Local (special‑application/pre‑engineered) aerosol systems are excluded and require separate approval and testing for the intended application.

Key topics and requirements

• Definitions and terminology for condensed aerosol fire‑extinguishing systems.
• Requirements and test methods for system components (generators, containers, discharge devices, etc.).
• Performance criteria and validation of extinguishant characteristics (electrical non‑conductivity, extinguishing effectiveness for specified fire types).
• Guidance for system design (total‑flooding application), sizing and arrangement to achieve effective coverage.
• Installation, commissioning, testing and periodic maintenance requirements and safety precautions.
• Limitations and exclusion of local/pre‑engineered applications unless specifically tested and approved.
• Documentation, marking and information to be supplied by manufacturers and installers.

Typical use and users

Used by manufacturers of condensed aerosol generators and components, fire‑safety system designers and engineers, installation and commissioning contractors, certification and test laboratories, facility/plant safety managers, and regulatory or approval authorities when evaluating total‑flooding aerosol extinguishing solutions for enclosed spaces.

Related standards

ISO 15779 is maintained by ISO/TC 21/SC 8 and is related in subject matter to other fire‑suppression and fire‑safety standards (for example standards addressing gaseous extinguishing agents, fire detection and alarm systems, and installation/maintenance practices). ISO lists an ISO/FDIS 15779 document under development as the follow‑on activity for this standard.

FAQ

Q: What is this standard?

A: ISO 15779:2011 is an international standard that sets requirements and test methods for components and provides guidance for the design, installation, testing and maintenance of condensed aerosol fire extinguishing systems (general requirements for total‑flooding systems).

Q: What does it cover?

A: It covers total‑flooding condensed aerosol systems using electrically non‑conducting aerosol extinguishants, including component test methods, performance validation, design and installation guidance, commissioning, maintenance and safety recommendations. Local/pre‑engineered applications are excluded from its scope.

Q: Who typically uses it?

A: Manufacturers, system designers, installers and commissioning engineers, test and certification bodies, facility safety managers and authorities having jurisdiction who evaluate or approve total‑flooding condensed aerosol systems.

Q: Is it current or superseded?

A: ISO 15779:2011 was published in November 2011 and was reviewed and confirmed in 2017. ISO indicates the document is under the normal lifecycle review and has had follow‑on work (ISO/FDIS 15779) indicated as the expected replacement path; users should check the ISO catalog for the latest status and any published revision or replacement.

Q: Is it part of a series?

A: It is part of ISO deliverables maintained under ISO/TC 21/SC 8 (fire‑fighting substances and systems) and relates to other international standards covering gaseous agents, system installation and fire protection practices; specific regional or national codes may also reference or supplement its requirements.

Q: What are the key keywords?

A: Condensed aerosol, aerosol generator, total flooding, extinguishant, component test methods, installation, maintenance, fire suppression, electrically non‑conducting.
