Fire Rated Assemblies - Compliance

What is considered an assembly within a fire rated door system?

Fire rated door systems are considered assemblies. As an assembly, the door, hardware and frame are to be in accordance with NFPA 80. If a component of a fire rated assembly is changed, then the change must result in the overall assembly being compliant. Just because a component, in and of itself, has the appropriate rating designation, it may not mean that the design of the resulting assembly of components has been accepted by the testing authority as compliant. As long as the component replaced is listed for use with the door in question, then the door assembly is compliant. If not, then the resulting altered assembly must be validated by a field study of the assembly by a qualified entity.
