Full-Scale Room Corner Fire Test Apparatus

Full-scale fire performance evaluation: Assess the fire behavior of wall and ceiling materials installed as in real applications.

Research and development: Study flame spread, smoke generation, and heat release of construction and decorative materials.

Fire safety certification: Evaluate materials for compliance with building codes and international fire safety standards.

Academic and scientific research: Investigate fire dynamics and corner fire phenomena that small-scale tests cannot replicate.

Compatible test components: Combustion chamber, smoke and sample gas collection system, gas analysis and data processing system, fuel supply system, sand-box burner.
