Product Introduction
The description of fire requires appropriate units of measurement, and the best way to represent and quantify fire is based on the speed at which energy is emitted and released. In today's discipline of fire, measuring heat release rate (HRR) is crucial, and the most accurate and effective measuring instrument for HRR is a conical calorimeter, which works by using the oxygen consumption method to determine heat release rate. The conical calorimeter has been widely accepted worldwide and can be used in large-scale combustion models, such as for furniture, cables, building materials, flame retardant materials, etc. It is likely to be the most important fire testing device in the future.
The instrument provides a new type of tool that not only meets the high requirements of researchers, but also meets the needs of the manufacturing industry.
Most major fire research groups use conical calorimeters as the primary source of material performance data and as input for models used for predicting fire behavior of finished products. International standards have been published and described for equipment, and some international standardization agencies have also published product standards for evaluating the performance of finished products using conical calorimeters.
