In the field of material combustion performance testing, the cone calorimeter is the core equipment, and its output parameters directly reflect the combustion characteristics of materials in a fire. The following are the key parameters for your detailed analysis:

1. Heat release rate (HRR)

This is the core parameter of the cone calorimeter, which refers to the heat released per unit time per unit area of the material during the combustion process, in kW/m ². It intuitively shows the intensity of material combustion. The higher the peak heat release rate, the faster the fire spread speed. It is the key basis for evaluating the fire hazard of materials and can provide core support for material selection in construction, transportation and other fields.

2. Mass loss rate (MLR)



This parameter reflects the combustion stability of the material. The faster the rate of mass loss, the more intense the burning of the material, the more obvious the phenomenon of melting and dripping during the combustion process, which is of great significance for evaluating the integrity of the material combustion process.

3. Effective Heat of Combustion (EHC)

It combines the relationship between heat release and mass loss, and can more accurately reflect the combustion efficiency of the material. If the effective combustion heat is too high, it indicates that the energy released during combustion is concentrated, and the fire hazard is greater.

4. Time to Ignite (TTI)

Refers to the time it takes for a material to be ignited from the action of a radiant heat source, in s. The longer the ignition time, the better the flame retardancy of the material, and the more difficult it is to ignite the material. It is an important basic parameter to measure the fire safety of materials and is crucial to the development and evaluation of fireproof materials.

Mastering these parameters can accurately determine the combustion characteristics of materials, providing a scientific basis for fire prevention and control, material research and development, and helping to build a safer material application system.
