IMO Flame Spread Test Apparatus is designed to evaluate the combustion behavior of materials used in buildings, high-speed trains, and marine applications. The apparatus focuses on key fire performance indicators such as flame spread rate, ignition heat, critical heat flux, and total heat release under controlled radiant heat exposure.
By exposing vertically mounted specimens to a calibrated radiant heat source and pilot flame, the system accurately measures flame propagation characteristics in accordance with relevant national and international standards. It is widely applied in construction, transportation, shipbuilding, and fire safety certification to assess material fire performance and compliance.
Application
Building Industry
Flame spread testing of construction materials such as wall linings, ceilings, partitions, and insulation boards to verify compliance with fire safety requirements.
High-Speed Railway
Evaluation of interior materials used in high-speed trains, including seats, wall panels, ceilings, and decorative components, to ensure passenger safety.
Shipbuilding and Marine Engineering
Fire performance testing of bulkhead, ceiling, and deck materials used in ships and offshore structures.
Fire Safety Testing and Certification
Measurement of flame spread rate, ignition heat, and heat release for fire-resistant material development and safety certification.
Material Manufacturers
Performance evaluation of plastics, rubber, composite materials, and other products under radiant heat exposure to improve fire protection properties.
Standards
The apparatus complies with the following standards:
(1) GB/T 28752-2012 – Test Method for Lateral Flame Spread on Vertical Surfaces
(2) ISO 5658-2 – Reaction to Fire Tests — Spread of Flame — Part 2: Lateral Spread on Building Products in Vertical Configuration
(3) IMO Resolution A.653(16) – Surface Flammability of Bulkhead, Ceiling and Deck Finish Materials
(4)ASTM E1317
