IFC is THE Source of Firestop Expertise that provides impartial and authoritative information, knowledge, resources, affiliation, techniques, and testing, to key stakeholders with an interest in passive fire protection (e.g. AHJ’s, contractors, manufacturers, other associations, fire services, owners, engineers, architects) because of our commitment and investment in industry research, development, testing, codes and standards advocacy, and manufacturing and unbiased and broad-based knowledge and representation. These recommended guidelines are presented as part of IFC’s educational information program. They are intended for informational and educational purposes.  \nThe Premise of Firestop Systems  \nFirestop systems deter the passage of fire, hot gases and toxic smoke through openingsin walls, floors and floor/ceiling assemblies for through penetrations, membrane penetrations, joints, blanks, gaps, voids and ducts. These systems are required by building codes to be tested and rated as part of an assembly in accordance with an approved test standard. Some of these are tabulated below:  \n\n| Fire Test Standards Commonly Referenced in Codes |  |  |\n| --- | --- | --- |\n| Application | Test Standard |  |\n| Service penetrations (e.g. pipes, cables, ducts) | ASTM E814, UL1479, CAN/ULC-S115, EN1366-3, EN 1366- 5, ISO 10295-1 |  |\n| Joint System | ASTM E1966, UL2079, CAN/ULC-S115, EN1366-4, ISO 10295-2, BS 476 Part 20 |  |\n| Perimeter Joint Firestops (e.g. exterior wall/floor intersections) | ASTM E2307, EN 1366-4 |  |\n| Continuity Head-of-Wall\u003Cbr>Joints (e.g. rated wall to nonrated floor/roof intersections) | ASTM E2837 |  |\n| Grease Ducts | ASTM E2336, UL2221, CAN/ULC-S144, EN1366-1, AS1530.4 |  |\n| Ventilation Ducts |  | ASTM E2816 (AC179), ISO 6944, EN1366-1, EN1366-8, AS1530.4 |\n\nAll elements of a tested and rated firestop system, including the assembly into which the system is installed, constitute a specific and inseparable engineered unit that must be utilized as such. Firestop system designs are tested and listed by independent testing agencies such as Underwriters Laboratories, Inc. (UL), Underwriters Laboratories of Canada (ULC), and Intertek. The specific elements of each design become integral to the listing.  \nWhen field conditions differ from original design or unanticipated construction hindrances are encountered and the field conditions cannot be easily or cost effectively redesigned, design recommendations are typically made to propose alternative methods that ensure performance of the firestop system is not compromised. These are sometimes referred to as “Engineering Judgments or EJs” (also known as “Technical Evaluations or TEs”), although other terms may apply dependent upon local practice. Since these recommendations are not based upon identical designs as that which were fire tested, it is important that they be developed using sound engineering principles and good judgment.  \nConstruction industry professionals, building officials, fire officials, firestop contractors and other stakeholders need appropriate guidelines for evaluating and using such judgments. As such, IFC developed Recommended IFC Guidelines for Evaluating Firestop Systems Engineering Judgments (EJs) .  \nIFC EJ Guidelines  \nEJs (TEs) for firestop systems should:  \n1. Not be used in lieu of tested systems when available;  \n2. 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;  \n3. Be based upon interpolation or extension of previously tested firestop systems that are either suffic","cbCaib9QH0PdLtq9","https://ap.wps.com/l/cbCaib9QH0PdLtq9","pdf",387763,"English","# About the IFC\n## The Premise of Firestop Systems\n# IFC EJ Guidelines\n## Basic Presentation Requirements","[{\"question\":\"What are engineering judgments (EJs/TEs) for firestop systems used for?\",\"answer\":\"They are recommendations used when field conditions differ from the original tested design or when unanticipated construction hindrances prevent straightforward redesign, while ensuring firestop performance is not compromised.\"},{\"question\":\"Who should issue firestop system EJs/TEs?\",\"answer\":\"They should 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.\"},{\"question\":\"What limitations apply to EJs/TEs?\",\"answer\":\"An EJ/TE should be limited to the specific conditions and configurations on which it was rendered, based on reasonable performance expectations, and accepted only for a single job and project location without transfer unless thoroughly reviewed.\"}]","Recommended IFC Guidelines for Evaluating Firestop System Engineering Judgments | PDF"]
