Building Materials Flame Retardancy Testing Machine Compliance With Standards: Complies With The Test Standards Of GB8625 And DIN4102

Compliance with standards: Complies with the test standards of GB8625 and DIN4102 "Test Method for Flame Retardancy of Building Materials".

Scope of application: It is mainly applicable to determining whether building materials are flame-retardant under specified conditions. Any material that has passed the combustion shaft furnace test and the flammability test of building materials can be classified as flame-retardant building materials.

Technical parameters
Combustion shaft furnace: It is composed of a combustion chamber, burner, test piece support, air stabilizer and flue, etc
Overall dimensions: Length 1020mm x width 1020mm x height 3930mm
Combustion chamber: Composed of furnace wall and furnace door, internal dimensions: 800mm in length x 800mm in width x 2000mm in height. The furnace wall is of an insulated sandwich structure.
Burner: Nozzle inner diameter 3.5mm, outer diameter 4.5mm. The distance from the bottom of the furnace is 1000mm.
Test stand: 380mm in length x 380mm in width x 1000mm in height, made of Angle steel.
Air stabilizer: It is a square frame set below the burner. A wire mesh is laid at the bottom, and a fiberglass mat is placed on top of it
Flue: It is square in shape, with each side measuring 500mm, and is located at the top of the furnace.
Control section: flowmeter, thermocouple, temperature recorder and temperature controller
Flowmeter: Methane is adjustable from 6 to 60L/MIN, and air is adjustable from 3 to 30L/MIN
Thermocouple: Armored thermocouple with a diameter of 3.0mm
Temperature recorder and thermostat: Multi-channel, capable of continuous temperature recording with curve display
The material of the chassis: The combustion box body is made of high-quality (t=1.2mm)304 stainless steel plate, processed by CNC machine tools, with a beautiful and elegant arc shape.
The frame is assembled with aluminum profiles, and the control box is made of high-quality (t=1.2mm) electrostatic steel plate, with a surface treated by powder coating, making it more smooth and beautiful.
All internal components are made of 304 stainless steel, which has good rust resistance.
