Fire Retardant Wood Stack Method Burning Test Equipment
The Fire Retardant Wood Stack Method Burning Test Equipment is developed with reference to GA/T 42.1, Fire Retardant Wood Combustion Performance Test Method – Wood Stack Method. The MDF-1 tester is used to determine the mass loss rate and flame burning time of wood with a thickness above 20 mm after flame-retardant impregnation treatment under specified combustion conditions.
Application
(1) Fire-Retardant Wood Testing – Evaluates the combustion performance of wood after flame-retardant treatment.
(2) MDF and Wood Products – Suitable for wood materials used in production and engineering applications.
(3) Material Quality Control – Determines mass loss and flame burning time under specified combustion conditions.
(4) Fire-Retardant Treatment Evaluation – Used to assess the combustion performance of wood following flame-retardant impregnation.
Standards
(1) GA/T 42.1 – Fire Retardant Wood Combustion Performance Test Method – Wood Stack Method
