Standard Guide for Extension of Data from Penetration Firestop System Tests Conducted in Accordance with ASTM E814

Importancia y uso:

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 Methods E119 and Test Method E814 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 E814, 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 E814.

4.6 This guide shall not be used to extrapolate the fire resistance rating to a higher value.

4.7 Limitations: 

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 Practice E2032.

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 E814 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 E814.

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.
