ABSTRACT

The toxic product yields of carbon monoxide and hydrogen cyanide from five bench scale methods are compared to large scale data under the range of flaming fire conditions. Data from the steady state tube furnace (SSTF)(ISO TS 19700), the fire propagation apparatus (FPA)(ASTM E 2058), the non-standard controlled atmosphere cone calorimeter (CAC), the smoke chamber (NBS)(ISO 5659) and the French railway test (NFX)(NF X 70-100) are compared to published large scale enclosure fire data (ISO 9705 room and 1/3 scale ISO room) for two polymers, polypropylene (PP) and polyamide 6.6 (PA 6.6). The results show good agreement between the SSTF, FPA and ISO room data for all materials and fire conditions. The CAC and NBS show reasonable agreement for well-ventilated burning, but fail to replicate the more hazardous underventilated fire condition. The NFX generates data intermediate between the wellventilated and under-ventilated fire conditions..
