It is the lowest temperature at which substance catches fire

Substance cannot catch fire unless it reaches its ignition temperature

Example - Ignition temperature of Diesel is 210 degree celsius

It means it does not catch fire until it reaches 210 degree celsius

 

Note

Ignition Temperature  is different for different products

 

Example

Ignition temperature of Diesel is 210 degree celsius but iron is 1315 degree celsius

It means diesel catches fire more easily as compared to iron

Petrol 247–280 °C (477–536 °F)
Diesel 210 °C (410 °F)
Phosphorus,white 34 °C (93 °F)
