Designation:E222615bAn American National StandardStandard Practice forApplication of Hose Stream1This standard is issued under the fixed designation E2226;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.INTRODUCTIONSeveral fire-test-response standards(such as ASTM E119,E814,E2074,and E1966)in order toassess the integrity of building elements after exposure to a specified test fire,require test specimensto be evaluated by exposure to a hose stream.It is important to standardize certain elements of the hosestream to promote uniformity in requirements.To attain this goal,this practice describes a standardapparatus for delivering a solid stream of water and prescribes a standard method of subjectingbuilding elements to a hose stream after fire exposure.1.Scope1.1 This practice is applicable to building elements requiredto be subjected to the impact,erosion,and cooling effects of ahose stream as part of a fire-test-response standard.Buildingelements include,but are not limited to,wall and partitionassemblies,fire-resistive joint systems,and doors.1.2 This practice shall register performance of the buildingelement under specific hose stream conditions.It shall notimply that,either after exposure or under other conditions,thestructural capability of the building element is intact or that thebuilding element is suitable for use.1.3 The result derived from this practice is one factor inassessing the integrity of building elements after fire exposure.The practice prescribes a standard hose stream exposure forcomparing performance of building elements after fire expo-sure and evaluates various materials and construction tech-niques under common conditions.1.4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 The text of this standard references notes which provideexplanatory material.These notes shall not be considered asrequirements of the standard.1.6 This fire standard cannot be used to provide quantitativemeasures.1.7 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:2E119 Test Methods for Fire Tests of Building Constructionand MaterialsE176 Terminology of Fire StandardsE631 Terminology of Building ConstructionsE814 Test Method for Fire Tests of Penetration FirestopSystemsE1966 Test Method for Fire-Resistive Joint SystemsE2074 Test Method for Fire Tests of Door Assemblies,Including Positive Pressure Testing of Side-Hinged andPivoted Swinging Door Assemblies(Withdrawn 2007)32.2 UL Standard:UL 385 Standard for Safety Play Pipes for Water SupplyTesting in Fire-Protection Service43.Terminology3.1 DefinitionsFor definitions of terms used in thispractice,refer to Terminologies E176 and E631.3.2 Definitions of Terms Specific to This Standard:1This practice is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.11 on FireResistance.Current edition approved Oct.1,2015.Published November 2015.Originallyapproved in 2002.Last previous edition approved in 2015 as E222615a.DOI:10.1520/E2226-15B.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from Underwriters Laboratories(UL),Corporate Progress,333Pfingsten Rd.,Northbrook,IL 60062.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.1 building element,na component or assembly ofmaterials using products manufactured as independent unitscapable of being joined with or placed within other compo-nents or assemblies to create a structure.3.2.2 exposed area,nthe total surface area of the testassembly that is subjected to the fire-resistance test including,when required,the supporting construction.3.2.3 fully developed stream,na coherent,forceful projec-tion of water similar in shape and intensity to the stream beingapplied to the exposed side of the test assembly from thenozzle.3.2.4 supporting construction,nconstruction required forthe testing of some building elements into which the testspecimen is assembled,for example,the wall into which a dooris fitted.3.2.5 test assembly,nthe building element or elementsbeing tested
