摘要: SUMMARY A new flame spread apparatus for the measurement of rates at different ambient temperatures is presented. A 2-m long sample pre-heated with air to desired temperature and ignited from its lower end a small propane burner. The traced thermocouples in contact surface. features function are described, as well series vertical experiments on cylindrical birch rods electrical cables made polyvinylchloride (PVC) retardant non-corrosive (FRNC) materials. Vertical 6–62 mm/s (temperature range 22–271 °C) were determined samples, 3–24 mm/s (22–190 °C) PVC cable 0–4 mm/s (22–293 °C) FRNC samples. Small-scale thermogravimetric analysis cone calorimeter performed characterize materials terms their thermal fire behaviour. Copyright © 2012 John Wiley & Sons, Ltd.
