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.
Help safeguard lives and property from fire risks by complying with requirements for accurately measuring the potential heat of building materials.
NFPA 259, Standard Test Method for Potential Heat of Building Materials, provides a means of determining a property-type measurement of the amount of heat that can possibly be given off by building materials when exposed to a heat source. A must-have for fire test labs, manufacturers, fire protection engineers, and fire researchers.
NFPA 259 covers:
Test apparatus and materials
Test specimens
Oxygen bomb calorimeter test procedures
Electric muffle furnace test procedures
Calculating potential heat
And more
Highlights
