Comparison of black and transparent PMMA in the cone calorimeter

This data set is a supplementary resource for the article "Comparison of Black and Transparent PMMA in the Cone Calorimeter", which will be published by ASTM international for the ASTM 42nd symposium on Obtaining Data for Fire Growth models. 

The information is structured into multiple *.zip folders. The directory named 'black' contains the data-files for the Black PMMA samples. The directory called 'transparent' contains the data-files for the Transparent PMMA samples. 

The files are structured in the following way: 

• Name: Material_color_measurement_heatflux_repetition (e.g.: PMMA_Black_HRR_25kWm2_R1).
• Each HRR file contains the following columns: Time in seconds, CO concentration in Vol%, CO2 concentration in Vol%, O2 concentration in Vol%, heat release rate per unit area in kW/m2. 
• Time t=0s corresponds to opening the shutter.

These files are not the raw data. CO, CO2 and O2 concentrations are measured as a voltage signal. This voltage signal is converted to a volume percentage using the calibration of the gas analyzer. The gas analyzer was calibrated at the beginning of every day. The analyzer showed a small drift over the time of the experiment. Therefore, a drift correction was done on the measured values. The concentrations in the data files have been corrected for this drift. The corrected concentrations were used to calculate the heat release rate. A surface area of 0.0088m2 was used to calculate the HRR per unit area.
