Gypsum Plasterboard Fire Resistance Tester
The Gypsum Plasterboard Fire Resistance Tester is designed in accordance with GB/T 9775-2008 to evaluate the fire stability performance of paper-faced gypsum boards used as non-load-bearing interior walls and ceiling systems in buildings.
The instrument applies a controlled flame to the test specimen and monitors combustion behavior, temperature response, and exposure time to determine the fire resistance stability of gypsum plasterboard products under standardized conditions.
The system integrates the test unit and control unit into a compact, integrated structure, ensuring reliable operation, precise control, and convenient observation during fire testing.
Applications
This tester is suitable for fire performance evaluation of the following specific products and application scenarios:
Paper-faced gypsum boards used for non-load-bearing interior partition walls.
Gypsum ceiling boards applied in suspended ceiling systems.
Fire-resistant gypsum boards for residential, commercial, and public buildings.
Decorative gypsum panels used in hotels, hospitals, offices, and shopping malls.
Gypsum board products developed for enhanced fire stability in building material R&D.
Quality control testing in gypsum board manufacturing plants.
Third-party inspection and certification laboratories verifying compliance with fire safety standards.
