Standard Test Method for Determining Ignition Temperature of Plastics

ASTM D 1929 Standard Test Method for Determining Ignition Temperature of Plastics  

The ASTM fire test procedure describes a laboratory determination of the flash ignition temperature (FIT) and spontaneous ignition temperature, or self-ignition temperature (SIT) of plastics and composites using a hot-air furnace. FIT is the minimum temperature at which sufficient flammable gases are emitted to ignite by a 

Plastic Physical form Average FIT, °C (°F) Repeatability (°C) Reproducibility (°C) 

Test values serve to rank materials according to ignition susceptibility under the actual use conditions. The procedure notes that specimens containing high levels of inorganic fillers are difficult to evaluate also, that the same material tested in different forms may give different results. 

The ASTM procedure describes in detail the hot-air ignition furnace with accessories, consisting primarily of an electrical heating unit, air source, specimen holder, thermocouples, pilot flame, and timing device.
