Protect lives with proper testing on door assemblies using the latest NFPA 252.

NFPA 252 outlines methods of fire testing door assemblies for determining assembly suitability when fire resistance of a specific duration is required.

The 2008 edition is updated to correlate with other documents:

  • Revised definition of 'fire door assembly' provides greater consistency with NFPA 80: Fire Doors and Other Opening Protectives
  • New reference to ASTM E 2226 replaces the Standard's detailed hose-stream test requirements

There's no substitute for the latest information for fire test laboratories and fire door manufacturers.
