  1. *C-Cubic, 4T—4 different temperatures, 3P—3 proportions.
  2. The fire testing approach was modified from the author’s prior work, involving subjecting samples to direct flame and adhering to customized ISO 834 standards for a shorter period (see Fig. 2)14. Open fire tests maintained a constant burning rate. The reported average temperature at the center of each face is as follows:
