摘要：In respect of fire resistance and fire integrity, the charring rate is the most important property of timber. It has been a worldwide research focus to develop a charring model for predicting the charring rate. The objective of this study is to establish an integral charring model, which is based on a tailored thermodynamic equation for commercial Chinese timber species. At 50 kW/m(2) heat flux, results show that the cone calorimeter can equal the furnace trials for testing the charring rate and also establish a charring rate model with a relative error of less than 20%. The integral model at a heat flux of 50 kW/m(2) is safer to predict the charring rate than the other two models.
