ZONSKY Flame Spread Tester is a device used to evaluate how flames spread across the surface of materials in a horizontal direction. This test simulates real fire conditions by applying a controlled flame to a sample placed in a defined testing area, allowing for the observation and measurement of flame characteristics.Talk To Our Team
Compliance:
ISO 5568-2:2006 “Reaction to fire tests – Spread of flame – Part 2: Lateral spread on building and transport products in vertical configuration”
IMO FTP Code Resolution A.653(16): “Recommendation on improved fire test procedures for surface flammability of bulkhead, ceiling, and deck finish materials.”
Flame Spread Tester Main Performance Parameters:
Instrument Composition:
The apparatus consists of a control cabinet, test device, a computer, a heat flow meter calibration device, and a smoke exhaust system.
Experimental Device:
It consists of a radiant plate support, sample support, igniter, and sample holder. The radiant plate support and the sample support are connected together.
Radiant Panel Support:
The radiant panel support is composed of steel pipe frame, radiant panel, and air supply part.
Steel Pipe Frame:
The steel pipe frame supports the radiant panel together with the corresponding gas supply pipeline system, safely driven and fixed. The steel pipe frame is composed of a square stainless steel pipe with a cross section of 40mm × 40mm, which is used to support the radiant panel. The central height of the radiant panel is (1200±100) mm, and the radiation is placed vertically. The angle between the surface and the front surface of the steel pipe frame is 5 (±3°).
Ignition Source: Radiant Panel and Propane Blowtorch:
Radiant Panel: It is composed of porous refractory tiles, which are fixed to the radiant surface, with a size of 450mm × 300mm. The panel is located at the rear of the radiant surface and consists of gas and air distribution pipes to smoothly transport the gas/air mixture and control the radiant flux required for the test by adjusting the amount of combustion. A wire mesh screen is provided in front of the radiant panel to increase the impedance, the radiant intensity can reach about 62kW/m², and the surface temperature can reach about 1300°C. The easy measurement of the radiant piece is convenient, and the heat spacing is 60mm.
The Heat Flux: During the specimen test, the radiant plate descends in a gradient along the long side of the specimen, with a starting point of 0 mm and ending at 450 mm. Heat flux values comply with the requirements of the standard.
Radiant Panel Temperature Control:
Control the Radiant Panel: The radiant panel temperature is adjusted by fine-tuning the air velocity to ensure the required heat flux. Solenoid valve that prevents the flame from spreading in front of the radiator, checks the temperature inside the radiator, and automatically shuts off the gas in case of flame extinction.
Flow Blocker:
The propane blowtorch flame is 150mm long, and it is applied to the sample at a distance of 20mm from the edge of the sample closest to the radiant plate.
