Two types of radiant panel apparatus are available for fire-related testing of cellulose insulation. One is the Flooring Radiant Panel (gas-fired radiant panel), an expensive piece of equipment that requires high operational and maintenance costs. The second type is the Veri-Flux “100” (electric radiant panel), also known as the Small-Scale Radiant Panel, which is currently being used as a quality control instrument in the cellulose insulation industry.
There have been few data published comparing the relative performance of the two instruments. This paper analyzes the performance of 53 samples of insulation when tested by these instruments. The analysis attempts to establish whether a direct comparison between the two instruments is feasible. The results of this study will be useful to an ASTM task group that is presently investigating the replacement of the larger gas-fired panel with the electric, small-scale panel.
