Rail transit is one of the most important ways of transportation today’s society, especially in the period of rapid development in China. With the development of special operation lines such as viaduct, tunnel and underground, the operation safety of rail transit has attracted great attention. Fire hazard has become the main hazard affecting vehicle operation. Therefore, fire prevention is very important for vehicle safe operation.
The surface spread flame tester belongs to BS6853 series high-speed rail flame retardant test instrument, which is used to measure the lateral extension of the sample surface and determine the the combustion grade based on the speed and elongation. By withstanding gradually changing radiant heat energy, ignite the sample with a small flame, and then determine its critical radiation flux. It is applicable to the British building materials and high-speed rail flame retardant test standard.
The instruments comply with BS 476-7:1997, BS 6853:1999 and other standards, and adopts PLC programmable program control, which makes human-computer interaction more convenient. Equipped with high-temperature detection device to automatically cut off the gas source and ensure safety. Use porous calibration plate and high-quality heat radiation flux sensor to automatically calibrate the curve. Provide water cooling circulation device to avoid damage caused by high temperature.
