NFPA 275 PDF

Reference the test methods specified in NFPA 275 to help increase safety and reduce damage and loss from fire in the built environment.

Many codes and standards include general requirements for portions of buildings to be separated by 15-minute thermal barriers. NFPA 275, Standard Method for Fire Tests for the Evaluation of Thermal Barriers, was created to address these critical fire protection components in more thorough and precise terms. The standard offers the methods for assessing a thermal barrier’s capacity to safeguard foam plastic insulation or metal composite materials (MCM) and prevent or delay ignition from exposure.

NFPA 275 provides fire test methods that identify sample construction, fire exposures, and acceptance criteria for use as a thermal barrier. Performance is determined by the ability to limit the temperature rise of unexposed surfaces and to remain intact to protect from ignition.
