Designation:E240415aAn American National StandardStandard Practice forSpecimen Preparation and Mounting of Textile,Paper orPolymeric(Including Vinyl)and Wood Wall or CeilingCoverings,Facings and Veneers,to Assess Surface BurningCharacteristics1This standard is issued under the fixed designation E2404;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.1.Scope1.1 This practice describes procedures for specimen prepa-ration and mounting when testing textile,paper,vinyl,ex-panded vinyl or other polymeric wall or ceiling coveringmaterials to assess flame spread and smoke development assurface burning characteristics using Test Method E84.1.2 This practice applies also to facings or wood veneersintended to be applied on site over a wood substrate(see 8.7).1.3 This practice applies also to water-resistive barriers thatare used as a component of exterior wall systems,as part of theexterior envelope(see 3.2.10 and 8.9).1.4 This practice does not apply to the following:1.4.1 Laminated products factory produced with a woodsubstrate,which are covered by Practice E2579.1.4.2 Water-resistive barriers comprised of foam plasticmaterials contained within the wall system(see 5.3.1).1.4.3 Water vapor retarders used,in conjunction with ther-mal insulation,on the interior or exterior side of an exteriorwall(see 3.2.11 and 5.3.1).1.5 Testing is conducted with Test Method E84.1.6 This practice does not provide pass/fail criteria that canbe used as a regulatory tool.1.7 Use the values stated in inch-pound units as thestandard,in referee decisions.The values in the SI system ofunits are given in parentheses,for information only;seeIEEE/ASTM SI-10 for further details.1.8 This fire standard cannot be used to provide quantitativemeasures.1.9 Fire testing of products and materials is inherentlyhazardous,and adequate safeguards for personnel and propertyshall be employed in conducting these tests.Fire testinginvolves hazardous materials,operations,and equipment.Thisstandard gives instructions on specimen preparation andmounting,but the fire-test-response method is given in TestMethod E84.See also Section 10.1.10 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.1.11 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotesshall not be considered requirements of the standard.2.Referenced Documents2.1 ASTM Standards:2C1186 Specification for Flat Fiber-Cement SheetsC1396/C1396M Specification for Gypsum BoardE84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE176 Terminology of Fire StandardsE2573 Practice for Specimen Preparation and Mounting ofSite-Fabricated Stretch Systems to Assess Surface Burn-ing CharacteristicsE2579 Practice for Specimen Preparation and Mounting ofWood Products to Assess Surface Burning CharacteristicsIEEE/ASTM SI-10 International System of Units(SI):TheModern Metric System2.2CSA Standard:3CSA O121 Douglas Fir Plywood2.3NIST Standard:4Voluntary Product Standard PS 1-07 Structural Plywood1This practice is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.22 on SurfaceBurning.Current edition approved June 1,2015.Published July 2015.Originally approvedin 2005.Last previous edition approved in 2015 as E2404-15.DOI:10.1520/E2404-15A.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 Canadian Standards Association(CSA),178 Rexdale Blvd.,Toronto,ON Canada M9W 1R3.4Available from National Institute of Standards and Technology(NIST),100Bureau Dr.,Gaithersburg,MD 20899-3460.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Terminology3.1 DefinitionsFor definitions of terms used in this prac-tice refer to the terminology contained in Terminology E176.3.2 Definitions of Terms Specific to This Standard:3.2.1 expanded vinyl wall or ceiling covering,na wall orceiling covering consisting of a woven textile backing,anexpanded vinyl base coat layer(which is a homogeneous vinyllayer that contains a blowing agent),and a nonexpanded vinylskin coat.3.2.2 paper wall or ceiling covering,na wall or ceilingcovering with a top layer consisting of paper or an alternativecellulosic-based material,but not consisting of a wood product.3.2.3 polymeric wall or ceiling covering,na wall orce
