Research on the influence of external environment on the thermal value testing results of building materials
The calorific value of combustion is an important indicator for evaluating the fire hazard of building materials,and its measurement accuracy is crucial for fire design and fire risk assessment.In order to study the influence of environmental temperature on thermal capacity calibration and combustion heat value,experiments are conducted using oxygen bomb calorimetry under different temperature conditions.The results show that an increase in environmental temperature can lead to a decrease in thermal capacity calibration value and combustion heat value,and temperature fluctuations significantly affected the stability of the results.It is recommended to strictly control the environmental temperature during the measurement process to improve the accuracy and reliability of the results.
