New Guide for Extension of Data for Fire-Resistive Joint Seals

    (What is a Work Item?)

    Developed by Subcommittee: E05.11 | Committee E05 | Contact Staff Manager


    1. Scope

    1.1 This guide covers the extension of results obtained from fire tests performed in accordance with Test Method E1966 to applications that have not been tested. Test Method E1966 evaluates the duration for which test specimens will contain a fire, retain their integrity, or both during a predetermined fire test exposure. Fire-resistive joints are intended for use in fire-resistive walls and floors that are evaluated in conformance with Test Method E119. 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 E814 for systems falling within the scope of Test Method E1966. This test method is a fire-test-response standard. Test Methods E119 and E814. 1.5 The types of building constructions, which are part of this guide, are as follows: floors, walls, partitions, and floor/ceiling and roof/ceiling assemblies, each with a fire rating. Assemblies can be the following: concrete floors or walls, masonry walls, gypsum walls, wood floor/ceiling assemblies (with wooden or steel framing), concrete floor/ceiling assemblies, and chase walls. 1.6 This guide applies to a joint between two building construction assemblies (listed above). 1.7 Dynamic or static joint seals shall be based on tested conditions for the same criteria. 1.8 The extension of data using numerical calculations based on empirical data or theoretical models is not covered in this guide. 1.9 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. 1.10 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. 1.11 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. 1.12 Units--The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.13 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 and health practices and determine the applicability of regulatory limitations prior to use.

    The purpose of this standard is to create a generalized guide for using data from firestop testing in accordance with E1966 and validating general conditions that are viewed as severe or less severe than the tested condition to extend the data to cover many other potential applications.
