WHAT … are Fire-Resistance Ratings ?

WHY … classify Types of Construction?

WHY … classify Types of Construction?Account for the response or participation (TIME) that a building’s structure will have in a fire

condition originating within the building as a result of its occupancy or fuel load.

WHY … classify Types of Construction?

HOW … do we determine FRR?

HOW … do we determine FRR?UL 263 : Standard for Fire Tests of Building Construction and Materials

Fire tests applicable to different assemblies.

Classifications intended to register performance during the period of fire exposure.

Evaluate the length of time that the types of assemblies specified in will contain a fire or retain their structural integrity, or both, dependent upon the type of assembly involved, during a predetermined test exposure.

Any variation from the construction or conditions that are tested such as size, method of assembly, and materials, may substantially change the performance characteristics of the assembly.
