2. Through Penetrants – One metallic pipe or tubing to be installed concentrically oreccentrically into opening such that the annular space between the pipe and the periphery of theopening is min 0 in. (point of contact) to max 2-1/2 in. Pipe to be firmly supported on both sides ofopening. The following types and sizes of pipes may be used:

Engineering Judgments (EJs):

• What are they?

• When are they acceptable?

• When are they not appropriate?

• What are the guidelines?


When are they acceptable?– When tested systems do not exist.– When modifying the application is unrealistic.– When existing test data supports the

interpolation. – When the author has experience with and

knowledge of the conditions. – When an illustration is provided to aid in

installation.


Sources of Engineering Judgements

• Manufacturer

• Third party labs (UL)

• Fire Protection Engineer

• Professional Engineer

Must be based on sound engineering practice and knowledge of both field application and capabilities

of system components


– According to the International Firestop Council “listed firestop systems can be broadened within the context of their originally tested and rated conditions through the careful and restricted application of accepted engineering principles and fire protection testing guidelines.”


About the IFCThe International Firestop Council is a not-for-profit association of manufacturers, distributors and installers of fire protective materials and systems.

IFC's mission is to promote the technology of fire containment in modern building construction through research, education and development of safety standards and code provisions.
