Abstract:

A series fire tests of cinema seats that were lined up were carried out in a 10 MW large scale calorimeter. The fire test platform was built. In the test, 15 cinema seats were arranged in three rows steps. Heat release rate, total heat release, smoke production rate, total smoke production were measure through the fire test of cinema row seats. Two group of ordinary cinema seats and two group of flame retardant cinema seats were compared and analyzed, and fire spread rate was calculated based on the teat data. The results indicate that：in the same way of ignition, flashover was happened within 8 min for ordinary cinema seats, the peak HRR and total THR value was 9.204 MW and 1 957.2MJ separately;After flame retardant treatment， the peak HRR and total THR value was decreased to 83.6 kW and 27.33 MJ，other combustion behavior parameters were decreased significantly; Once ordinary cinema seats were ignited, flame spread fast and the flame spread rate was calculated as 0.65 m/min.  

Key words: cinema seats, heat release rate, calorimeter, row seats
