Figure 10
The illustration displays two plots labeled “a” and “b,” each depicting heat release rate (H R R) over time from cone calorimeter tests. In both plots, the vertical axis is labeled “H R R in kilowatt meter to the negative 2 power” and ranges from 0 to 140 with an interval of 35. The horizontal axis is labeled “Time (seconds)” and ranges from 0 to 1800 with an interval of 600. In plot “a,” the legend includes three curves labeled “C R 50 at the rate of 50 kilowatt meters to the negative 2 power” (orange), “C R 50 at the rate of 35 kilowatt meters to the negative 2 power” (blue), and “C R 40 at the rate of 50 kilowatt meters to the negative 2 power” (blue). All the curves start from the origin and then rise rapidly to the sharp peaks and then decrease with a fluctuating pattern, which ends at the lower value of the H R R on the far right side. The orange curve shows a peak at time 115 at H R R of 125, the red curve shows the peak at time 116 marked as T T I at H R R of 116 marked as p H R R, and the blue curve peaks at time 480 at H R R of 112. A small inset plot “Raw C R” is also shown above the curves. The vertical axis is labeled “H R R in kilowatt meter to the negative 2 power” and ranges from 0 to 500 with an interval of 250. The horizontal axis is labeled “Time (seconds)” and ranges from 0 to 1800 with an interval of 600. The blue curve, which represents “50 kilowatt meters to the negative 2 power,” starts from the original, rises rapidly and attains a peak, and then decreases towards the right with small fluctuations. The red curve, which represents “35 kilowatt meters to the negative 2 power,” starts from the origin and follows the same pattern as the blue one, but it peaks slightly lower than the blue curve. In plot “b,” the legend includes “R 8-50 at the rate of 50 kilowatt meters to the negative 2 power” (red) and “R 8-40 at the rate of 50 kilowatt meters to the negative 2 power” (blue). All the curves start near the origin and then rise rapidly to the sharp peaks and then decrease with a fluctuating pattern, which is slightly larger than the plot (a), and ends at the lower value of the H R R on the far right side. The red curve shows the peak at time 269 at H R R of 109 marked as p H R R, and the blue curve peaks at time 293 marked as T T I at H R R of 73 marked as p H R R. A small inset plot “Raw R 8” is also shown above the curves. The vertical axis is labeled “H R R in kilowatt meter to the negative 2 power” and ranges from 0 to 500 with an interval of 250. The horizontal axis is labeled “Time (seconds)” and ranges from 0 to 1800 with an interval of 600. The blue curve, which represents “50 kilowatt meters to the negative 2 power,” starts from the original, rises rapidly and attains a peak, and then decreases towards the right with small fluctuations. The red curve, which represents “35 kilowatt meters to the negative 2 power,” starts from the origin and follows the same pattern as the blue one, but it peaks slightly lower than the blue curve.Cone calorimeter results of HRR curves of SCB with (a) CR and (b) R8.
