Designation:E159205(Reapproved 2012)Standard Test Method forStructural Performance of Sheet Metal Roof and SidingSystems by Uniform Static Air Pressure Difference1This standard is issued under the fixed designation E1592;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.INTRODUCTIONComputations are the accepted method for determining the structural capacity of most metalproducts.However,some conditions are outside the scope of analysis by industry specifications.Methods of computation and a discussion of these conditions are found in the following documents:AISI Specification for the Design of Cold-Formed Steel Structural Members and Load and ResistanceFactor Specification for Cold-Formed Steel Structural Members and Aluminum Association Specifi-cations for Aluminum Structures.This test method is not to be considered as a wind design standard.It is a structural capacity testto determine the ability of a panel system(including attachments)to resist uniform static pressure.Actual wind pressure is nonuniform and dynamic.These uniform static test results should be used inconjunction with commonly recognized wind design standards,and will yield highly conservativeresults.When additional fasteners are installed across panel flats at eaves,ridges,or reinforced end laps,thecrosswise distortion is eliminated and both flexural capacity and anchor-to-panel attachment strengthcan vary with the distance from such conditions.This test procedure can be used to evaluate thestrength of panels and attachments at any distance from end or edge perimeter conditions.The size ofthe specimen and limitations on air seals are designed to minimize any interference with the naturalresponse of the panels under load.1.Scope1.1 This test method covers the evaluation of the structuralperformance of sheet metal panels and anchor-to-panel attach-ments for roof or siding systems under uniform static airpressure differences using a test chamber or support surface.1.2 The provisions of this test method are applicable tostanding seam,trapezoidal,ribbed,or corrugated metal panelsin the range of thickness from 0.012 to 0.050-in.(0.3 to1.3-mm)and apply to the evaluation of uniform pressureapplied to single-skin construction or one sheet metal layer ofmultiple-skin construction.They do not cover requirements forthe construction of a specimen to determine the load sharingthat can occur with either composite or multiple-layer con-struction such as:(1)metal cladding over wood sheathing;or(2)field assemblies of insulation sandwiched between corru-gated or formed metal panels.1.3 Proper use of this test method requires knowledge of theprinciples of pressure and deflection measurement.1.4 This test method describes optional apparatus and pro-cedures for use in evaluating the structural performance of agiven system for a range of support spacings or for confirmingthe structural performance of a specific installation.1.5 The values stated in inch-pound units are to be regardedas the standard.The metric equivalents of inch-pound units areapproximate.1.6 The text of this standard references notes and footnotesexclusive of those for tables and figures.These notes andfootnotes provide explanatory material and shall not be con-sidered as requirements of the standard.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is the1This test method is under the jurisdiction of ASTM Committee E06 onPerformance of Buildings and is the direct responsibility of Subcommittee E06.57on Performance of Metal Roof Systems.Current edition approved April 1,2012.Published May 2012.Originallyapproved in 1995.Last previous edition approved in 2005 as E1592 05.DOI:10.1520/E1592-05R12.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 responsibility 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.For specificprecautionary statements,see Section 7.2.Referenced Documents2.1 ASTM Standards:2A370 Test Methods and Definitions for Mechanical Testingof Steel ProductsB557 Test Methods for Tension Testing Wrought and CastAluminum-and Magnesium-Alloy Products2.2 Aluminum Association Standard:3Aluminum Formed-Sheet Building Sheathing DesignGuide,Appendix B of Specifications for AluminumStructures,Latest Edition2.3 AISI Standards:4Specification for the Design of Cold-Formed Steel Struc-tural Members,Latest Edition2.4 Other Documents:ASCE7(Formerly ANSI A58.1)Minimum Design Loadsfor Buildings and Other Structures53.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 anchor,na fastener,bolt,screw,or formed devicesuch as a clip th
