The '''fire point''', or '''combustion point''', of a [fuel](/source/fuel) is the lowest temperature at which the liquid fuel will continue to burn for at least five seconds after ignition by an open flame of standard dimension.<ref>{{Cite book|last1=Steven A.|first1=Treese|title=Handbook of Petroleum Processing|last2=Peter R.|first2=Pujado|last3=David S. J.|first3=Jones|publisher=Springer|year=2015|isbn=978-3-319-14528-0|edition=2|pages=1736}}</ref> At the [flash point](/source/flash_point), a lower temperature, a substance will ignite briefly, but vapour might not be produced at a rate to sustain the fire. Most tables of material properties will only list material flash points. In general, the fire point can be assumed to be about 10 °C higher than the flash point,<ref name=ntt/> although this is no substitute for testing if the fire point is [safety critical](/source/Safety-critical_system).<ref name=ntt/> 

Testing of the fire point is done by [open cup apparatus](/source/Cleveland_open-cup_method).<ref name=ntt>{{cite web|url=http://www.nttworldwide.com/tech2212.htm|title=Flash Point and Fire Point|accessdate=2010-05-27|url-status=dead|archiveurl=https://web.archive.org/web/20101214222420/http://www.nttworldwide.com/tech2212.htm|archivedate=2010-12-14}}</ref><ref>[https://www.astm.org/Standards/D92.htm "Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester"], ASTM.org</ref>
