what is the difference between something that is combustable and something that is flamable?

Answer 1

Here's one regulatory definition of the terms "flammable" and "combustible":

Answer 2

It depends on what standard you are looking at. Flammable materials have a higher vapor pressure and lower flash point than combustable materials do. For the US Department of Transportation the magic number is 141°F -- anything with a flashpoint below is flammable, above 141°F is combustable (up to 200°F).

Answer 3

combutable means the the complete and utter reaction of a hydrocarbon, and that the reaction equation of the hydro carbon with oxygen will not change through out the whole reactions. flamable means it could be wood which is not made up of 100% hydrocarbons, and for examble something thats flamable: thermite, completely flamable when lit and doesn't contain one bit of hydrocarbons.

Answer 4

wood , cotton, paper ..etc. are combustable meterials , it burns when catch fire, and reached their Ignition degree.,flamable meterials , like Benzene , alcohol are highly flamable , have a low flash points and high vapor pressure (volatile easily) and when reach its flah point ignite with flame, any spark also ignite the flamable substances when their are vapor of them.

Answer 5

Something combustible can catch fire without a flame (overly hot conditions). Something flammable is highly sensitive near or around fire.

Answer 6

combustable - can burst (like a bomb)
flamable - can go on fire

Answer 7

combustable has the potential to explode whereas flammable can simply catch fire.

propane tanks are combustible and lighter fluid is flammable.

Answer 8

its something like sounds,, combustable ,,blust , explode .. flameable catch flame and burn smoothly with no pressure,,

Answer 9

combustable- blows up
flammable- simply catches fire

Answer 10

They usually mean the same thing.
