Burning rate and flame heat flux for PMMA in a cone calorimeter
BT Rhodes, JG Quintiere - Fire Safety Journal, 1996 - Elsevier
Ignition and burning rate data are developed for thick (25 mm) black Polycast PMMA in a
cone calorimeter heating assembly. The objective is to establish a testing protocol that will
lead to the prediction of ignition and burning rate from cone data. This is done for a
thermoplastic like PMMA. The incident flame heat flux, for irradiation levels of 0–75 kW/m2,
is found to be approximately 37 kW/m2 for black PMMA. Its constancy is shown due to the
geometry of the cone flame. Also, this flame is shown to be nearly transparent for cone …
