The invention provides a flame propagation testing apparatus and application method thereof. The apparatus comprises a casing with a hollow structure; a rotary testing frame portal with one end flexibly connected to the casing; a sample fixing apparatus connected to the rotary testing frame portal; an infrared radiation plate connected to the casing, wherein the infrared radiation plate and the rotary testing frame portal are on a same plane of the casing; a flame ignitor connected to the infrared radiation plate; and a gas supplying device arranged in the inner space of the casing, wherein the gas supplying device is connected to the infrared radiation plate. The flame propagation testing apparatus further comprises a controlling device independently arranged outside the casing, wherein the controlling device is connected to the casing through a communication cable. The apparatus provided by the invention is an actual application of a BS476-7 method. Also, according to the invention, the controlling device is arranged. The push-button layout of the human-computer interaction interface of the device is arranged according to technological logic. An operator can operate according to the indications of blinking indicator lights, such that routine operations can be carried out. Abundant alarming and noticing information is provided on the human-computer interaction interface, such that the operator can conveniently learn current equipment status in time.
Description
technical field [0001] The invention relates to a flame-retardant test of building materials and rail transit materials, in particular to a flame propagation test device and a method for using the same. Background technique [0002] Flame combustion of materials must involve the flammability of the main material and the level of flame propagation, thus endangering life. British Standards Committee Building Materials and Components Burning Tests Part 7: Test Methods for Determining the Classification of Surface Spread of Flame of Products (BS476-7) This standard is a test method for judging the flammability of materials. This method allows the surface spread of flame to be tested to assess its true fire situation. At present, there is no mature device for BS476-7 testing in China, and the BS476-7 standard only roughly introduces the general configuration of the device for testing, and does not configure easy-to-use, reliable and safe control schemes and methods in detail . ...
