1.1 This guide covers the extension of results obtained from fire tests performed in accordance with Test Method E814 to applications that have not been tested. Test Method E814 evaluates the duration for which test specimens will contain a fire, retain their integrity, or both during a predetermined fire test exposure. Firestops are intended for use in fire-resistive walls and floors that are evaluated in conformance with Test Methods E119.

Note 1: Data obtained from firestops tested in accordance with Test Methods E119 with positive pressure can also be used.

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.

1.3 These principles are only applicable to temperature conditions represented by the standard time-temperature curve described in Test Method E814, for systems falling within the scope of Test Method E814. This test method is a fire-test-response standard.

1.4 The types of building constructions which are part of this guide are as follows: floors, walls, partitions, floor/ceiling and roof/ceiling assemblies.

1.5 This guide applies to:

1.5.1 a single penetrating item, or

1.5.2 multiple penetrating items.

1.6 This guide does not apply to joints systems tested to Test Methods E119, E1966, E2307, and E2837.

1.7 Penetrating items can be one of the following: metallic pipe, non-metallic pipe, metallic tubing, non-metallic tubing, metallic conduit, non-metallic conduit, flexible metal conduit, cables, cable trays, bus ducts, insulated pipes, insulated tubing, insulated conduit, insulated and non-insulated ducts, and structural members.

Metallic pipe, tubing or conduit 6.7 Insulated pipe, tubing or conduit 6.8 Non-metallic pipe, tubing or conduit 6.9 and 6.10 Flexible metal conduit 6.11.1.4 and 6.11.1.5 Cables 6.11 Cable tray 6.12 Bus duct 6.13 Non-insulated duct 6.14 Insulated duct 6.14.2 Non-structural or service support member 6.15 Mixed penetrations 6.16

1.8 Assemblies can be one of the following; concrete floors or walls, masonry walls, gypsum walls, wood floor/ceiling assemblies, concrete floor/ceiling assemblies, chase wall in floor/ceiling assemblies and fire-rated insulated walls.

Concrete floors or walls 6.1 Masonry walls 6.1 Gypsum board wall assemblies 6.2 Wood floor/ceiling assemblies 6.3 Floor/ceiling assembly with concrete floor 6.4 Chase wall intersecting a floor/ceiling assembly 6.5 Fire-resistance insulated walls 6.6

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

1.10 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.

1.11 This guide is used to predict or provide a quantitative 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.

1.12 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.

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

1.14 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.

1.15 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.
