1、Designation:E235314Standard Test Methods forPerformance of Glazing in Permanent Railing Systems,Guards,and Balustrades1This standard is issued under the fixed designation E2353;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year
2、 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.1.Scope1.1 These test methods cover procedures to be followed intesting the performance of glazing in permanent railingsystems,gua

4、atforms.1.2 These test methods are applicable to such railing,guard,and balustrade systems having glass or other glazing materialsas the major structural component or the infill panel includingswing gates and other forms of guardrail protection.1.3 These test methods can be used to determine whether
5、permanent rails,guards and balustrades including components,having glass or other glazing material comply with require-ments of performance specifications,codes,norms,and stan-dards.1.4 Specifically,these test methods cover procedures fordetermining the static strength,impact performance,and post-br
6、eakage characteristics of railing systems,guards,andbalustrades,including a component with glass or other glazingmaterial installed in one,two,three and four-side supportsystems fastened to concrete,masonry,wood,metal,andrelated products.1.5 No consideration is given in these test methods to anyposs
7、ible deterioration of the railing,guard,or balustradesystem or their connections and fasteners as resulting fromadverse environmental or in-service conditions.The perfor-mance of special tests covering this aspect may be desirable.1.6 These test methods are limited to the application ofloads and imp
8、act resistance described herein.Whenever uni-formly distributed loads are to be resisted by a railing system,guard,orbalustradeinaccordancewithgoverningspecifications,codes,norms,and standards,the effects of suchloads on the member stresses shall be determined by calcula-tion and the corresponding c
9、oncentrated and linear loads shallbe tested.Should computations make it possible to provide theneeded information,testing can be employed for verification.1.7 These test methods address the capability of glass orother glazing material rails,guards,and balustrades in one,two,three and four-sided supp
10、ort systems to continue in theirfunction as a barrier by remaining in the designed framingsystem after impact or glass breakage.These test methods donot address structural limitation of glass rails,guards,andbalustrades or vehicular guards except when in the area of apedestrian walkway.1.8 The value
11、s 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.1.9 This standard does not purport to address all of thesafety concerns,if any,associated with its
12、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:2E329 Specification for Agencies Engaged in ConstructionInspection,Testing,o
