This guide covers the extension of results obtained from fire tests performed in accordance with Test Method E 1966 to applications that have not been tested. Test Method E 1966 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 E 119. Note 1: Data obtained from firestops tested in accordance with ASTM E119 with positive pressure can also be used. 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. These principles are only applicable to temperature conditions represented by the standard time-temperature curve described in Test Method E 1966, for systems falling within the scope of Test Method E 1966. This test Method is a fire-test-response standard. The types of building constructions which are the part of this guide are categorized as follows; floors, walls, partitions, floor/ceiling and roof/ceiling assemblies.
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, in order to extend the data to cover many other potential applications.
