Also known as the "room corner" test, NFPA 286, Standard Methods of Fire Tests for Evaluating Contribution of Wall and Ceiling Interior Finish to Room Fire Growth, provides a method of determining the flammability characteristics of exterior, non-load bearing wall assemblies and panels that are required to be of non-combustible construction but may contain combustible components.

Vital for testing laboratories, NFPA 286 addresses all wall coverings, including textile wall coverings.

Measurements in the fire test room document the extent of fire growth, rate of heat release, total heat released, time to flashover, time to flame extension, total heat flux incident to the floor, upper level gas temperature, smoke obscuration, production of carbon monoxide, and emissions of other combustion gases.

The 2024 Edition includes:

• Updates to reference documents and a new section in Chapter 5 on specimen mounting for reflective insulation, radiant barrier, and vinyl stretch materials.
