Abstract: The cone calorimeter is a standard device for evaluating material fire behavior. While general test setups follow standards (e.g., ISO 5660, ASTM E1354), key operational parameters - like sensor placement, ventilation, and ambient airflow - can vary. These flexible parameters can significantly influence calibration and key measurements like heat release rate (HRR), yet their effects are not well documented. This lack of clarity can lead to inconsistent or non-comparable results across measurements. In this study, we systematically investigate how variations in sample placement, hood position, and ventilation (influenced by door configuration) affect critical outputs including HRR, smoke production, and flow field dynamics. By quantifying these influences, we aim to enhance the reliability and reproducibility of cone calorimeter experiments. Additionally, this research aims to improve the scientific validation of the cone calorimeter as a reliable tool for academic and research-based fire testing applications.
