Significance and Use
4.1 The methods and procedures set forth in this guide relate to the extension of the fire test results to firestop systems that have not been tested.
4.2 Users of this guide must have knowledge and understanding of the provisions of Test Method and Test Method including those pertaining to conditions of acceptance.
4.3 In order to apply some of the principles described in this guide, reference to the original fire test report will be necessary.
4.4 In Test Method , the specimens are subjected to specific laboratory fire test exposure conditions. Differences between the tested assembly and the as-built assembly impact the fire-test-response characteristics. Substitution of different test conditions also impacts the fire-test-response characteristics.
4.5 The extension of data is valid only for the fire test exposure described in Test Method .
4.6 This guide shall not be used to extrapolate the fire resistance rating to a higher value.
4.7.1 The extension of fire resistance data is to be used only for changes to the tested specimen that fall within normal and reasonable limits of accepted construction practices.
4.7.2 Conclusions derived from using this guide are valid only if the identified change is the only change in the construction or properties of the components.
4.7.3 Evaluation of changes to the fire-resistive assembly in which the firestop is installed is governed by the Extension of Data principles in Guide .
4.8 The statements in this guide are based on a single change to a system.
Note 2: It is possible that multiple changes have a different cumulative effect than that of individual changes evaluated separately. The principles contained herein may provide useful information for the application of sound engineering principles to evaluate the effect of multiple differences between tested and installed firestops.
4.9 Extensions of data using this document shall be done by individuals possessing the following minimum qualifications and attributes:
4.9.1 an understanding of the Test Method test procedure,
4.9.2 an understanding of the fire behavior of firestop materials,
4.9.3 knowledge of the elements of the construction to be protected, and
4.9.4 an understanding of the probable behavior of the underlying construction and the recommended firestop system protecting it, were they to be subjected to testing in accordance with Test Method .
4.10 The person performing evaluations based on tested or listed firestops shall be one of the following:
4.10.1 the firestop manufacturer's knowledgeable and qualified technical personnel,
4.10.2 a registered professional engineer, or Fire Protection Engineer, knowledgeable in firestopping systems,
4.10.3 an independent testing agency or a listing agency, or
4.10.4 technical personnel with experience in firestopping.
1.1 This guide covers the extension of results obtained from fire tests performed in accordance with Test Method to applications that have not been tested. Test Method evaluates the duration for which test specimens will contain a fire, retain their integrity, or both during a predetermined fire test exposure. Firestops are intended for use in fire-resistive walls and floors that are evaluated in conformance with Test Method .
Note 1: Data obtained from firestops tested in accordance with Test Methods with positive pressure can also be used.
1.2 This guide is based on principles involving the extension of test data using simple considerations. The acceptance of these principles and their application is based substantially on an analogous worst-case proposition.
1.3 These principles are only applicable to temperature conditions represented by the standard time-temperature curve described in Test Method , for systems falling within the scope of Test Method . This test method is a fire-test-response standard.
1.4 The types of building constructions which are part of this guide are as follows: floors, walls, partitions, floor/ceiling and roof/ceiling assemblies.
1.5 This guide applies to:
1.5.1 a single penetrating item, or
1.5.2 multiple penetrating items.
1.6 This guide does not apply to joints systems tested to , and .
1.7 Penetrating items can be one of the following: metallic pipe, non-metallic pipe, metallic tubing, non-metallic tubing, metallic conduit, non-metallic conduit, flexible metal conduit, cables, cable trays, bus ducts, insulated pipes, insulated tubing, insulated conduit, insulated and non-insulated ducts, and structural members.
Metallic pipe, tubing or conduit
Insulated pipe, tubing or conduit
Non-metallic pipe, tubing or conduit
Flexible metal conduit
Non-structural or service support member
1.8 Assemblies can be one of the following; concrete floors or walls, masonry walls, gypsum walls, wood floor/ceiling assemblies, concrete floor/ceiling assemblies, chase wall in floor/ceiling assemblies and fire-rated insulated walls.
Concrete floors or walls
Gypsum board wall assemblies
Wood floor/ceiling assemblies
Floor/ceiling assembly with concrete floor
Chase wall intersecting a floor/ceiling assembly
Fire-resistance insulated walls
1.9 The extension of data using numerical calculations based on empirical data or theoretical models is not covered in this guide.
1.10 This guide does not cover the substitution of one proprietary material for another proprietary material, or materials for which fire-test data are not presently available.
1.11 This guide is used to predict or provide a quantitative measure of the fire hazard from a specified set of fire conditions involving specific materials, products, or assemblies. This assessment does not necessarily predict the hazard of actual fires which involve conditions other than those assumed in the analysis.
1.12 This guide is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.
1.13 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.14 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.15 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
