Flash point

Minimum temperature at which a fuel generates enough vapor to create an atmosphere that ignites in the presence of an ignition source, but insufficient to sustain combustion.

Flash point; fire point

Temperature (above the flash point) at which a fuel generates enough vapor to ensure sustained combustion after ignition by an ignition source.

Autoignition temperature

Temperature at which a mixture ignites in the absence of any ignition source.

Limite inférieure d'explosivité; lower explosive limit

Concentration below which the fuel/fuel mixture is too lean for combustion.

Limite supérieure d'explosivité; upper explosive limit

Concentration above which the...
