Best Answer

A material that is flammable catches on fire from a minimal source. For example, propane can catch fire from just a tiny spark.

A material that is combustible or combustile is any material that will burn but requires a more dominant source. For example, wood is combustile, it burns, but it needs more than just a spark to do so.

All flammable material are combustible but not all combustible material are flammable

Is diesel flammable?

Actually, Diesel is not flammable, it is combustible. The difference is the flash point. Diesel does not flash until 143 degrees Fahrenheit. Anything between 100 and 200 is combustible; less than 100 is flammable. Compare it to "gasoline" which has a flash point of -42 F (I think).

What is the difference between flammable and combustible material?

A flammable material has a lower flash point (100F or below) while a combustible material has a flash point of 100F or HIGHER. In other words, it's a lot easier for a flammable material to catch fire than a combustible one because of the minimal amount of energy (heat) required to get it going versus the higher requirement of a combustible material.
