1、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.
2、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
3、 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
4、 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-man
5、ce 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 exposure
6、s.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 cri
7、teria 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 suitabi
8、lity 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
9、 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
10、.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
11、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,pr
12、oducts,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 perso
