ME Petroleum are an oil trading company. They have a page of Jet Fuel facts, where they explain that the standard specification of Jet Fuel is JET A-1 (a.k.a JET A).
They also claim the "Maximum burning temperature" of Jet A-1 fuel is 980 °C.
(While this page doesn't make any claims about 9/11, this page is frequently cited by 9-11 conspiracy theorists; it is used to argue that jet fuel could not have burned hot enough to weaken the steel structures of the World Trade Center towers. Whether that is true or not is outside the scope of this question.)
The question is whether jet fuel burns at a higher temperature than the one given.
(I suspect that, in context, the page is actually referring to the maximum operating temperature that a jet engine should have for the fuel to retain the properties required to operate the engine, rather than the maximum temperature that an uncontrolled fire involving the fuel can reach, but I would like some definite information on this subject.)
