What is UL 10C certification and why does it matter for door hinges?

Question

Accepted Answer

UL 10C is the Positive Pressure Fire Test standard administered by Underwriters Laboratories for door assemblies and their components. When a door hinge carries UL 10C certification, it has been independently tested under simulated fire conditions with positive pressure applied to the unexposed side of the door — replicating real fire dynamics. For D&D Hardware's hinges, this certification confirms that the hinge maintains the fire door's structural integrity for a full 3 hours (180 minutes) under these demanding conditions, preventing the passage of flame and hot gases through the door assembly. This certification is legally required by NFPA 80 for all hardware installed on fire-rated door assemblies in the United States.
