Door and Roller Shutter Fire Resistance Test Furnace
The Door and Roller Shutter Fire Resistance Test Furnace is designed to evaluate the fire performance of doors and roller shutters installed in vertical partition openings. It is suitable for hinged doors, pivot doors, horizontal sliding doors, vertical sliding doors (including linked sliding doors and sectional doors), roller shutters, other sliding, folding, tilting doors, and movable wall-integrated panels. The furnace meets GB/T7633-2008 requirements and is intended for fire resistance testing of non-load-bearing horizontal doors and roller shutters.
Applications
(1) Fire resistance testing of hinged, pivot, sliding, folding, and tilting doors in residential, commercial, and industrial buildings.
(2) Fire performance evaluation of roller shutters in industrial and commercial environments.
(3) Fire testing of movable panels and specialized wall-integrated doors for non-load-bearing applications.
(4) Product development, quality control, and certification for door and roller shutter manufacturers targeting export markets.
(5) Research and verification for fire safety engineering projects, ensuring compliance with international fire regulations.
(6) Evaluation of building components’ compliance with NFPA, ISO, ASTM, EN, and BS fire safety standards.
