Designation:E196615An American National StandardStandard Test Method forFire-Resistive Joint Systems1This standard is issued under the fixed designation E1966;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.INTRODUCTIONJoint systems are positioned in joints,voids,gaps,or other discontinuities between or bounded bytwo or more supporting elements.Normally such openings are denoted as“linear”because the lengthis greater than their widthdefined by a typical ratio of at least 10:1 as in practice.Joints are presentin buildings as a result of:(i)Design to accommodate various movements induced by thermal differentials,seismicity,andwind loads and exist as a clearance separation.(ii)Acceptable dimensional tolerances between two or more building elements,for example,between non-loadbearing walls and floors.(iii)Inadequate design,inaccurate assembly,repairs or damage to the building.1.Scope1.1 This fire-test-response test method measures the perfor-mance of joint systems designed to be used with fire ratedfloors and walls during a fire endurance test exposure.The fireendurance test end point is the period of time elapsing beforethe first performance criteria is reached when the joint systemis subjected to one of two time-temperature fire exposures.1.2 The fire exposure conditions used are either thosespecified by Test Method E119 for testing assemblies tostandard time-temperature exposures or Test Method E1529 fortesting assemblies to rapid-temperature rise fires.1.3 This test method specifies the heating conditions,meth-ods of test,and criteria for the evaluation of the ability of ajoint system to maintain the fire resistance where hourly ratedfire-separating elements meet.1.4 Test results establish the performance of joint systemsduring the fire-exposure period and shall not be construed ashaving determined the joint systems suitability for use afterthat exposure.1.5 This test method does not provide quantitative informa-tion about the joint system relative to the rate of leakage ofsmoke or gases or both.However,it requires that suchphenomena be noted and reported when describing the generalbehavior of joint systems during the fire endurance test but isnot part of the conditions of compliance.1.6 Potentially important factors and fire characteristics notaddressed by this test method include,but are not limited to:1.6.1 The performance of the fire-resistive joint systemconstructed with components other than those tested.1.6.2 The cyclic movement capabilities of joint systemsother than the cycling conditions tested.1.7 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.1.8 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.1.9 This standard is used to measure and describe theresponse of materials,products,or assemblies to heat andflame under controlled conditions,but does not by itselfincorporate all factors required for fire hazard or fire riskassessment of the materials,products,or assemblies underactual fire conditions.1.10 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.1.11 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.1This test method is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.11 on FireResistance.Current edition approved June 1,2015.Published July 2015.Originally approvedin 1998.Last previous edition approved in 2011 as E196607(2011).DOI:10.1520/E1966-15.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.Referenced Documents2.1 ASTM Standards:2E84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE119 Test Methods for Fire Tests of Building Constructionand MaterialsE176 Terminology of Fire StandardsE631 Terminology of Building ConstructionsE1529 Test Methods for Determining Effects of Large Hy-drocarbon Pool Fires on Structural Members and Assem-bliesE2226 Practice for Application of Hose StreamE2307 Test Method for Determining Fire Resistance ofPerimeter Fire Barriers Using Intermediate-Scale,Multi-story Test Apparatus3.Terminology3.1 Definitions:3.1.1 For the purpose of this standard,the definitions
