Designation:E2750131An American National StandardStandard Guide forExtension of Data from Penetration Firestop System TestsConducted in Accordance with ASTM E8141This standard is issued under the fixed designation E2750;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEThe title of this guide was corrected editorially in February 2013.1.Scope1.1 This guide covers the extension of results obtained fromfire tests performed in accordance with Test Method E814 toapplications that have not been tested.Test Method E814evaluates the duration for which test specimens will contain afire,retain their integrity,or both during a predetermined firetest exposure.Firestops are intended for use in fire-resistivewalls and floors that are evaluated in conformance with TestMethod E119.NOTE1Data obtained from firestops tested in accordance with TestMethods E119 with positive pressure can also be used.1.2 This guide is based on principles involving the exten-sion of test data using simple considerations.The acceptance ofthese principles and their application is based substantially onan analogous worst-case proposition.1.3 These principles are only applicable to temperatureconditions represented by the standard time-temperature curvedescribed in Test Method E814,for systems falling within thescope of Test Method E814.This test method is a fire-test-response standard.1.4 The types of building constructions which are part ofthis guide are as follows:floors,walls,partitions,floor/ceilingand roof/ceiling assemblies.1.5 This guide applies to:1.5.1 a single penetrating item,or1.5.2 multiple penetrating items.1.6 This guide does not apply to joints systems tested toE119,E1966 and E2307.1.7 Penetrating items can be one of the following:metallicpipe,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 struc-tural members.Metallic pipe,tubing or conduit6.7Insulated pipe,tubing or conduit6.8Non-metallic pipe,tubing or conduit6.9 and 6.10Flexible metal conduit6.11.1.4 and 6.11.1.5Cables6.11Cable tray6.12Bus duct6.13Non-insulated duct6.14Insulated duct6.14.2Non-structural or service support member6.15Mixed penetrations6.161.8 Assemblies can be one of the following;concrete floorsor walls,masonry walls,gypsum walls,wood floor/ceilingassemblies,concrete floor/ceiling assemblies,chase wall infloor/ceiling assemblies and fire-rated insulated walls.Concrete floors or walls6.1Masonry walls6.1Gypsum board wall assemblies6.2Wood floor/ceiling assemblies6.3Floor/ceiling assembly with concrete floor6.4Chase wall intersecting a floor/ceiling assembly6.5Fire-resistance insulated walls6.61.9 The extension of data using numerical calculationsbased on empirical data or theoretical models is not covered inthis guide.1.10 This guide does not cover the substitution of oneproprietary material for another proprietary material,or mate-rials for which fire-test data are not presently available.1.11 This guide is used to predict or provide a quantitativemeasure of the fire hazard from a specified set of fire conditionsinvolving specific materials,products,or assemblies.Thisassessment does not necessarily predict the hazard of actualfires which involve conditions other than those assumed in theanalysis.1.12 This guide is used to measure and describe the re-sponse of materials,products,or assemblies to heat and flameunder controlled conditions,but does not by itself incorporateall factors required for fire hazard or fire risk assessment of thematerials,products or assemblies under actual fire conditions.1This standard guide is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.11 on FireResistance.Current edition approved Jan.1,2013.Published February 2013.Originallyapproved in 2011.Last previous edition approved in 2011 as E2750-11.DOI:10.1520/E2750-13E01.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 1.13 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.14 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C168 Terminology Relating to Thermal InsulationE119 Test Methods for Fire Tests of Building Constructionand MaterialsE176 Terminology of Fire StandardsE631 Terminology of Building Co
