Product Details
ZY6263 Lateral Spread of Flame Test Apparatus
Brief Introduction
The Horizontal Flame Spread Tester delivers precise surface-burn metrics to help manufacturers assess material fire hazards.
Highlights / Outstanding Features / Characteristics
- Horizontal Propagation Testing: Specifically engineered to measure and observe how fire spreads laterally across flat material surfaces.
- Controlled Fire Simulation: Features a defined testing area that exposes samples to a highly regulated, repeatable flame source.
- Behavioral Diagnostics: Allows engineers to closely monitor, measure, and record specific flame characteristics and burning rates.
- Safety Verification: Provides the necessary data to evaluate raw materials and finished components for industrial fire safety standards.
Description
In compliance with:
- ISO 5568
- IMO FTP Code Resolution A.653(16)
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.
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.
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:
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.
