Abstract:

The ASTM E119 test procedure (or equivalent) is used to determine whether a construction assembly or structural element meets the fire resistance rating requirements specified in prescriptive building codes. Fire statistics indicate that these requirements appear to be adequate in meeting the intended fire safety objectives of the prescriptive codes. In recent years it has become more common to design buildings for fire safety on a performance basis. The standard fire resistance test in its present form is not designed to provide discrete information that can be used in support of performance-based structural fire design. The technology of the test standard could be improved to make the measurements and results more useful for performance-based fire design. This report presents the results of a study undertaken by the Foundation to develop the technical basis for changes and additions to ASTM E119 so that measurements and results can be used in performance-based design, without compromising the traditional use of the test standard for prescriptive building code compliance.
