Material as such does not get any rating. It’s always the complete Firestop systems which get tested and awarded a rating. Each component of the assembly plays a crucial role in the performance of the firestop material. The firestop system consists of: ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Size of the material of the penetrant The type of assembly being penetrated The type and thickness of insulation used on the penetrant, if any The size and configuration of the opening, The annular space between the penetrant and the periphery of the opening The type of firestopping material etc. Therefore, whenever a tested is selected, it is important for the stakeholder to consider each component into consideration and then choose a firestop system from the testing lab listing database.
