1.1 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.
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.
1.4 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.
1.7 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.
1.9 This standard is used to determine certain fire-test responses of materials, products, or assemblies to heat and flame under controlled conditions by using results obtained from fire-test-response standards. The results obtained from using this standard do not by themselves constitute measures of fire hazard or fire risk.
