Description

technical field [0001] The invention relates to a measuring instrument for flame retardancy of materials, in particular to a cone calorimeter for measuring parameters such as material heat release rate, effective combustion heat and smoke density based on the principle of oxygen consumption. Background technique [0002] The development of flame retardant science and technology has put forward higher and higher requirements for the evaluation and testing methods of flame retardant materials' combustion behavior; traditional testing methods such as: oxygen index method, vertical combustion method, and horizontal combustion method, although they have operational It is simple, fast, and repeatable, and is still widely used in many combustion test laboratories. However, these methods generally have shortcomings such as single test parameters and unquantifiable test results, which are difficult to correlate with the combustion behavior of materials in real fire conditions. Theref...
