Standard Guide for Fire-Resistance Experiments
SIGNIFICANCE AND USE
4.1 The methods and procedures set forth in this guide relate to the conduct and reporting of fire-resistance tests obtained from particular fire-resistance tested specimens tested using conditions different than those addressed by Test Methods E119.
4.2 Data derived from fire tests conducted and reported under this guide are useful for general fire research and as potential input data for use in fire models.
4.3 It is necessary that users of this guide have knowledge and understanding of the provisions of Test Methods E119, including those pertaining to conditions of acceptance in order to understand how the alternative test conditions relate to those specified in Test Methods E119.
4.4 Users of this guide should be aware that tests conducted using exposure conditions different than those specified in Test Methods E119 do not provide or generate fire resistance ratings suitable for determining compliance with code or regulatory requirements.
4.4.1 In Test Methods E119, standard test specimens are subjected to specific exposure conditions. Substitution of different exposure conditions can change the measured fire-test-response characteristics of a test specimen. Therefore, the data are valid for only the alternative exposure conditions used.
SCOPE
1.1 This guide covers the conduct of fire-resistance tests using conditions different than those addressed in Test Methods E119. This guide also addresses the reporting of data derived from those tests.
1.2 This guide does not provide or generate fire-resistance ratings suitable for determining compliance with code or regulatory requirements comparable to those resulting from tests conducted in accordance with Test Methods E119.
1.3 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.
1.4 This guide is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.
1.5 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
This guide provides a means for ensuring comparability of findings among different researchers
conducting fire-resistance experiments employing innovative and creative variations to standard test
methods. This guide is intended to bring uniformity and consistency to tests and reports covering
fire-resistance research that is generally conducted as a variation of Test Methods E119. Its provisions
are voluntary and users are free to pick and choose from the provisions herein provided. The
overriding goal is to make it possible to begin to provide data that ultimately can be used in fire safety
engineering and fire-resistance modeling as those fields evolve. When the purpose of the research is
to study the effect of changing specific individual variables on the outcome of Test Methods E119
fire-resistance tests, sound research practices dictate that only one variable should be changed at a
time.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
