Full title and description
St AS 2427-2004 (2016) — Smoke/heat release vents. Australian Standard specifying performance, construction and installation requirements for buoyancy‑driven smoke and heat exhaust vents mounted in roofs to release products of combustion in the event of fire. The 2004 edition was formally reconfirmed in 2016 (no technical changes), and remains the active Australian Standard for roof-mounted smoke/heat release vents.
Abstract
This standard sets out mandatory requirements and performance criteria for natural (buoyancy-driven) smoke and heat release vents intended for roof installation. It defines key performance parameters (such as required vent area and aerodynamic properties), construction and material considerations, and references test methods used to verify vent behaviour under fire conditions. It is intended to ensure vents provide an effective, reliable means of releasing smoke and heat to assist occupant protection and fire-fighting operations.

- Number of pages: 11 (official publication).
Scope
Specifies requirements for buoyancy‑driven smoke and heat exhaust vents intended for installation in the roofs of buildings to release products of combustion in the event of fire. The standard covers performance and construction requirements applicable to such vents and refers to associated test methods used to assess vent behaviour and effectiveness. It is focused on natural (non‑mechanical) vents and does not replace specific building code provisions or other standards where additional requirements apply.
Key topics and requirements
- Definition and classification of smoke/heat release vents (buoyancy‑driven roof vents).
- Performance requirements for vent opening area and effective aerodynamic area to ensure adequate exhaust of smoke and heat.
- Construction and material requirements to ensure structural integrity and fire‑resistance during operation.
- Requirements for vent actuation and automatic operation where applicable (opening mechanisms and release temperatures/controls).
- Reference to test methods and measurement parameters (including methods for determining discharge coefficient and effective aerodynamic area, and other AS 2428 series test procedures).
- Installation considerations and interaction with other building fire protection systems (for example sprinkler systems and mechanical smoke control where relevant).
- Marking, documentation and manufacturer information to support selection, installation and maintenance.
Typical use and users
Used by building designers, fire engineers, ventilation and roof product manufacturers, façade and roof component suppliers, building certifiers, fire safety consultants and authorities having jurisdiction. Typical applications include industrial and commercial buildings, warehouses and other occupancies where roof‑mounted natural smoke/heat vents are specified as part of the passive smoke control strategy or to complement mechanical exhaust systems.
Related standards
Commonly referenced and related documents include the AS 2428 series (methods of testing smoke/heat release vents), maintenance standards for fire protection equipment, Australian/NZ product and installation standards covering roof openings and rooflights, and international equivalents or complementary standards (for example NFPA 204 and relevant BS/EN documents on smoke and heat control). Always check local building code and jurisdictional requirements for mandatory cross-references.

FAQ
Q: What is this standard?
A: AS 2427-2004 (reconfirmed 2016) is the Australian Standard that specifies requirements for buoyancy‑driven smoke and heat release vents mounted in building roofs to release products of combustion during a fire.
Q: What does it cover?
A: It covers performance and construction requirements for natural roof smoke/heat vents, key parameters such as vent area and aerodynamic properties, actuation and documentation requirements, and it references associated test methods for verifying vent behaviour.
Q: Who typically uses it?
A: Building designers, fire engineers, manufacturers and suppliers of roof vents, installers, fire safety consultants, and building regulators or certifiers use the standard when selecting, specifying, testing and approving roof smoke/heat release vents.
Q: Is it current or superseded?
A: The 2004 edition (3rd edition) was formally reconfirmed in 2016 and remains current (i.e., in force with reconfirmation). It supersedes earlier editions from 1981/1983.
Q: Is it part of a series?
A: Yes. AS 2427 is associated with the AS 2428 series of documents that specify methods of testing smoke/heat release vents and related test procedures; other complementary Australian standards and codes address installation, maintenance and wider smoke control systems.
Q: What are the key keywords?
A: smoke vent, heat vent, roof vents, buoyancy-driven, discharge coefficient, aerodynamic area, fire safety, vent testing, AS 2427.
