ASTM E 3201 : 2025

1.1This guide covers the extension of results obtained from fire tests performed in accordance with Test Method E1966 to applications that have not been tested. Test Method E1966 evaluates the duration for which test specimens will contain a fire, retain their integrity, or both during a predetermined fire test exposure. Fire-resistive joint systems are intended for use in fire resistance rated walls and floors that are evaluated in conformance with Test Methods E119.

1.2This 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.

1.3These principles are only applicable to temperature conditions represented by the standard time-temperature curve described in Test Method E1966, for systems falling within the scope of Test Method E1966.

1.4This guide does not apply to penetration systems tested to Test Methods E119 and E814.

1.5The included types of building constructions for this guide, should be as follows: floors, roofs, walls, partitions, floor/ceiling and roof/ceiling assemblies, each with a fire resistive rating.

1.6The included type of assemblies for this guide should be the following: concrete floors or walls, masonry walls, gypsum walls, floor/ceiling assemblies (with wood or steel framing), concrete floor/ceiling assemblies, roofs and chase walls.

1.7This guide applies to joints between or bounded by two building construction assemblies (listed above).

1.8Dynamic or static joint systems should be based on tested conditions for the same criteria.

1.9The extension of data using numerical calculations based on empirical data or theoretical models is not covered in this guide.

1.10This 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.

1.11This guide is used to predict or provide a measure of the fire hazard from a specified set of fire conditions involving specific materials, products, or assemblies. This assessment does not necessarily predict the hazard of actual fires, which involve conditions other than those assumed in the analysis.

1.12This guide is used to 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.

1.13Units—The values stated in SI units should be regarded as the standard. No other units of measurement are included in this standard.

1.14This 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.

1.15This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.

1.16This 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.
