IFC developed Recommended IFC Guidelines for Evaluating
Firestop Systems Engineering Judgments (EJs).
IFC EJ Guidelines
EJs for firestop systems should:
■ ■
■ ■
Not be used in lieu of tested systems when available;
Be issued only by a firestop manufacturer’s qualified technical
personnel or in concert with the manufacturer by a knowledgeable
registered Professional Engineer, Fire Protection Engineer, or an
independent testing agency that provides listing services for firestop
■ ■
systems;
Be based upon interpolation or extension of previously tested firestop
systems that are either sufficiently similar in nature or clearly bracket
the conditions upon which the judgment is to be given. Additional
knowledge and technical interpretations based upon accepted
engineering principles, fire science and fire testing guidelines (e.g.
ASTM E 2032 – Standard Guide for Extension of Data From Fire
Resistance Tests Conducted in accordance with ASTM E 119, ULC
Subject C263E – Criteria for Use in Extension of Data from Fire
Endurance Tests, or ASTM E2750 – Standard Guide for Extension of
Data from Penetration Firestop System Tests conducted in Accordance
■ ■
with ASTM E814) may also be used as further support data;
Be based upon full knowledge of the elements of the construction to
be protected and an understanding of the probable behavior of that
construction and the recommended firestop system protecting that
construction if it was subjected to the appropriate Standard Fire Test
method for firestops for the rating indicated on the EJ;
