70-SFA100 Spread of Flame Apparatus measures the flame spread of the materials. The IMO marine specification includes a collection hood for heat release measurement. The apparatus is constructed depending on the requirements of the standard and essentially two main items, the radiant panel framework and the specimen support framework, and many supplementary items.
Specifications
Electrical
230 Volts AC 50 Hz or 115 Volts AC 60 Hz
Gas supply
The radiant panel of the apparatus can burn propane or natural gas. Typical gas supply requirements are a flow of up to 0.8 litres/second at a supply pressure of 200 mm water gauge.
Air supply
Air supply of up to 10 litres/second and at a supply pressure of approximately 300 mm water gauge is required
Dimensions (W×H×D)
The radiant panel has overall dimensions of approximately 480 mm by 280 mm
Features
The panel is manufactured from all-welded square tubular with mild steel material and includes all the associated pipework and control valves for the radiant panel
The panel consists of porous refractory tiles mounted in a stainless steel housing and it is mounted on the support framework on a rotating steel ring which allows the specimen for the testing in different orientations
It is designed for use with natural gas or propane gas and the gas is mixed with air before entry to the panel
The pressure governors and control, it has shut off valve for both gas and the air
Integrated with variable area flowmeters in the pipework to allow the gas and air to the radiant panel to be controlled and monitored
Consist fixed control box to the framework which contains indicators of lamps and push-buttons associated with the gas safety system
The framework which supports the test specimen is made from all-welded square tubular mild steel sections
One side of the framework contains a steel guide which carries the specimen holder
In the test position, the surface of the specimen at the end of adjacent to the radiant panel is brought close to a test flame from a stainless steel tube fixed to the support frame and supplied with gas/air mixture from the main gas supplies on the radiant panel support framework
The heat release stack us mounted on the specimen support framework and directly above the test specimen, such that the combustion products rising from a vertically mounted specimen are channelled into the stack
The specimen support framework is connected to the support frame for the radiant panel by the spacer and fixing bolts
The stainless steel specimen holder is constructed according to the requirements and specifications
A spring-type loaded quick action clamp for easy loading and retention of the test specimen is also provided
It has a calibration board and a heat flux meter
The calibration board is made with calcium silicate-based board material and is provided with a series of holes, when the calibration board is inserted into the test apparatus, positions the heat flux meter at prescribed calibration locations
The output from the meter can be monitored on a suitable recording device or from the optional data acquisition and software system
It consists specially designed device which enables the outputs from the thermocouple on the heat release stack to be conditioned as required based on the specification
Applications
The Spread of Flame Apparatus measures the flame spread of materials in marine and railway applications
Lab Expo Flammability Tester can accurately evaluate the fire resistance of materials under controlled conditions. They feature adjustable flame height and exposure time to simulate different testing scenarios. Their chamber is constructed with durable, heat-resistant materials to ensure safe operation. They support both vertical and horizontal sample positioning for versatile applications. Our Flammability Tester provides consistent, standardized, and dependable performance.
