Designation:C1201/C1201M15Standard Test Method forStructural Performance of Exterior Dimension StoneCladding Systems by Uniform Static Air PressureDifference1This standard is issued under the fixed designation C1201/C1201M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of the struc-tural performance of dimension stone cladding systems underpositive and negative uniform static air pressure differences,using a test chamber.1.2 The proper use of this test method requires a knowledgeof the principles of pressure and deflection measurement.1.3 This test method describes the apparatus and the proce-dure to be used for applying either specific test loads orunknown ultimate values of uniformity distributed test loads toa specimen.1.3.1 Procedure A(see 11.2)shall be used when deflectionsat maximum load only are required.1.3.2 Procedure B(see 11.3)shall be used when a load-deflection curve is required.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 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.For specific hazardstatements,see Section 7.2.Referenced Documents2.1 ASTM Standards:2C1799 Guide to Dimension Stone Test Specimen Samplingand Preparation2.2 ANSI Standard:ANSI A58.1 Building Code Requirements for MinimumDesign Loads in Buildings and Other Structures32.3 AAMA Standard:AAMA TIR-A2 Design Wind Loads for Aluminum CurtainWalls43.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 permanent deformationthe permanent displacementfrom an original position that remains after an applied load hasbeen removed.3.1.2 specimenthe entire assembled unit submitted for testas described in Section 8.3.1.3 test loadthe specified difference in static air pressure(positive or negative)for which the specimen is to be tested,expressed in pounds-force per square foot Pascals.3.1.4 ultimate loadthe difference in static air pressure(positive or negative)at which failure of the specimen occurs,expressed in pounds-force per square foot Pascals.4.Summary of Test Method4.1 This test method consists of sealing the test specimeninto or against one face of a test chamber;supplying air to,orexhausting air from,the chamber at the rate required tomaintain the test-pressure difference across the specimen;andobserving,measuring,andrecordingthedeflection,deformations,and nature of any failures.5,61This test method is under the jurisdiction of ASTM Committee C18 onDimension Stone and is the direct responsibility of Subcommittee C18.01 on TestMethods.Current edition approved May 1,2015.Published July 2015.Originally approvedin 1991.Last previous edition approved in 2009 as C120109.DOI:10.1520/C1201_C1201M-15.2For 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.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.4Available from American Architectural Manufacturers Association(AAMA),1827 Walden Office Square,Suite 550,Schaumburg,IL 60173-4268.5ASHRAE Handbook of Fundamentals,American Society of Heating,Refrigerating,and Air-Conditioning Engineers,Inc.,Chapter 26,1977.6“Wind Forces on Structures,”Transactions of the American Society of CivilEngineer,Vol 126,Part II,Paper 3269,1961,pp.11241198.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.Significance and Use5.1 This test method gives a standard procedure for deter-mining structural performance under uniform static air pressuredifference.This typically is intended to represent the effects ofwind loads on exterior building surface elements.The actualloading on building surfaces is quite complex,varying withwind direction,time,height above ground,building shape,terrain,surrounding structures,and other factors.These factorsare discussed in the literature in 2.2 and 2.3 and Footnotes 4and 5.NOTE1In applying the results of tests by this test method,it shouldbe borne in mind that the performance of a cladding system may be afunction of fabrication,installation,and adjustment,and that the specimenmay or may
