文摘

Flammability of two kinds of two extruded polystyrene foam was tested by micro-scale combustion calorimeter and cone calorimeter. Maximum specific heat release rate, specific heat release, heat release temperature, combustion time and fire growth rates from micro-scale combustion calorimeter tests, and time to ignition, effective net heat of combustion, heat release rate from cone calorimeter tests, were used to compare the flammability of two foams. These two methods would draw different results in evaluating flammability of the foams. This confliction is due to the test scale and combustion condition. The relationship between these two methods can be established with ignition temperature; thus, micro-scale combustion calorimeter can be used to predict time to ignition in cone calorimeter tests. Joint using of micro-scale combustion calorimeter and cone calorimeter leads to a comprehensive evaluation of flammability of polymers.
