Hereinafter referred to as: thermal release rate
Parameter method:
Software operating system: it can collect and record total oxygen consumption, oxygen concentration, carbon dioxide concentration, temperature, heat release rate (HRR), total heat release (THR), effective heat of combustion (EHC), orifice flowmeter, thermocouple , C coefficient, flue gas flow rate, time to ignition(TTI), ignition time (temperature), rest time, critical ignition heat, thermal weight loss rate, nasty release rate, toxic gas generation rate, mass loss rate (MLR ) and other test data output, it can be saved and printed; it has powerful functions, especially for multi-curve comparison, which can intuitively compare the difference in burning characteristics of materials.
Gas analyzer: imported from Siemens, Germany. Oxygen (O2); T90 response time ≤3.5S; Dioxide (CO2), carbon monoxide (CO): T90 response time ≤3.5S. T90 response time is very important and directly determines the authenticity of the collected data.
Average Pyrolysis Rate and Radiant Energy
1. During the test, set different radiation energies after calibrating the cone calorimeter, and carry out 3 parallel tests under each radiation energy. The initial data of the sample
2. According to the principle of higher thermal release rate and shorter ignition time (the principle of the most dangerous fire), select a reasonable value as the actual application data, so that each material can
