What is NFPA 259?
NFPA 259: Document Scope
1.1* Scope. This method of test shall provide a means of determining, under controlled laboratory conditions, the potential heat of building materials subjected to a defined high-temperature exposure condition. A.1.1 Determinations can be made on individual homogeneous or individual composite, nonhomogeneous, or layered materials from which a representative sample can be taken.

This test method provides a means of determining, under controlled laboratory conditions, the potential heat of building materials subjected to a defined high-temperature exposure condition.

Official document scope
What does NFPA 259 address?

The procedures yield a property-type measurement of the amount of heat that can potentially be given off by building materials exposed to a heat source of 759 degrees C. Specimens are tested using an oxygen bomb calorimeter and an electric muffle furnace.
