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.
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
