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 .
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 , including those pertaining to conditions of acceptance in order to understand how the alternative test conditions relate to those specified in Test Methods .
4.4 Users of this guide should be aware that tests conducted using exposure conditions different than those specified in Test Methods do not provide or generate fire resistance ratings suitable for determining compliance with code or regulatory requirements.
4.4.1 In Test Methods , 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.
1.1 This guide covers the conduct of fire-resistance tests using conditions different than those addressed in Test Methods . 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 .
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 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 and health practices and determine the applicability of regulatory limitations prior to use.
