Standard Guide for Extension of Data From Fire Resistance Tests Conducted in Accordance with  E 119
 N E2032

Annotation

This guide covers the extension of fire resistance ratings obtained from fire tests performed in accordance with Test Method E119 to constructions that have not been tested. Test Method E119 evaluates the duration for which test specimens will contain a fire, retain their standard integrity, or both during a predetermined test exposure.

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 E119. Test Method E119 is a fire-test-response standard.

The types of building constructions which are the subject of this guide are categorized as follows: beams; floor and roof assemblies; columns; and walls and partitions. Floor and roof assemblies include such assemblies with ceiling protective membranes.

The extension of test data using numerical calculations based on empirical data or theoretical models is not covered in this guide.

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.

This guide does not purport to be comprehensive in its treatment of non-proprietary modifications of tested constructions. Engineering evaluation or tests are recommended for assessing modifications not specifically covered in this guide.

The values stated in SI units are to be regarded as standard.
