The cone calorimeter is the core equipment for material combustion performance testing. It focuses on the key parameters of materials in real combustion scenarios, providing accurate data support for safety research and development and quality control in various industries. Its detection content is directly related to the safety level of materials. It is an indispensable testing tool in scientific research and production.

Core Detection Indicator 1: Heat Release Rate (HRR)

Heat release rate is the most critical test item of the cone calorimeter. It refers to the heat released per unit area and unit time of the material, which directly reflects the intensity of heat release of the material in the fire. By simulating the radiant heat source environment of a real fire, the device can capture the heat release curve during the combustion of the material in real time. Peak heat release rate (pHRR) is the core indicator to measure the fire hazard. The higher the value, the stronger the risk of fire spread. This data is an important basis for material selection in construction, transportation and other fields.

Core Test Indicator 2: Total Heat Release (THR)

The total heat release is the total heat released by the material from ignition to complete extinguishment, which reflects the overall energy scale of the fire. Unlike the heat release rate, which focuses on the instantaneous heat release intensity, the total heat release reflects the continuous hazard ability of the fire. The larger the value, the wider the range of heat hazards caused by the fire and the longer the duration. This indicator has important reference value for evaluating the long-term fire risk of materials and formulating fire prevention and control strategies.

Core Test Indicator 3: Effective Heat of Combustion (EHC)

Effective combustion heat refers to the effective heat released when a unit mass of material is burned, which reflects the efficiency of energy conversion during the combustion process of the material. The higher the effective combustion heat, the more concentrated the energy released during the combustion of the material, and the easier it is to exacerbate the fire; conversely, it means that the material combustion energy is released slowly and the fire hazard is relatively low. This indicator is of great significance for evaluating the energy utilization efficiency of material combustion and the difficulty of fire prevention and control.

Core Detection Indicator 4: Quality Loss Rate (MLR)

The mass loss rate is the amount of mass loss of a material per unit time during the combustion process, which directly reflects the burning speed and complete degree of combustion of the material. The faster the mass loss rate, the faster the material burns, the more rapid the fire development; at the same time, combined with the mass loss curve, the carbonization of the material can also be judged. Materials with good carbonization will form a carbon layer on the surface and hinder combustion, which is one of the characteristics of high-quality flame retardant materials.

Core Detection Index 5: Flue Gas Generation Characteristics

The cone calorimeter can also detect the flue gas generation rate (SPR) and total flue gas generation (TSP) when the material is burned. Flue gas is one of the main factors causing death in fires. By measuring these parameters, the toxicity and concentration of flue gas when the material is burned can be evaluated. It provides data support for the development of low-smoke and non-toxic flame retardant materials, which is essential to ensure the safety of personnel in fires.

Core application scenario: material flame retardancy and fire safety evaluation

With the above accurate detection capabilities, cone calorimeters are widely used in building insulation materials, transportation interiors, electronic and electrical shells, textile fabrics, and other fields, which can not only help enterprises develop flame retardant materials that meet safety standards, but also provide products with fire safety level assessments. This provides a scientific basis for the industry to formulate safety standards and build a strong fire prevention and control line.
