Designation:E257915An American National StandardStandard Practice forSpecimen Preparation and Mounting of Wood Products toAssess Surface Burning Characteristics1This standard is issued under the fixed designation E2579;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 wood products to assessflames spread and smoke development as surface burningcharacteristics using Test Method E84.1.2 This practice applies also to laminated products factory-produced with a wood substrate(see 8.6).This practice doesnot apply to wood veneers or facings intended to be applied onsite over a wood substrate,which are covered by PracticeE2404.1.3 Testing is conducted with Test Method E84.1.4 Testing for the reporting of the moisture content of thetest specimen is conducted with Test Methods D4442.1.5 This practice does not provide pass/fail criteria that canbe used as a regulatory tool.1.6 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.1.7 This fire standard cannot be used to provide quantitativemeasures.1.8 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 and equipment.This standardgives instructions on specimen preparation and mounting,butthe fire-test-response method is given in Test Method E84.Seealso Section 10.1.9 The text of this standard references notes and footnoteswhich provide explanatory materials.These notes and foot-notes shall not be considered requirements of the standard.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.2.Referenced Documents2.1 ASTM Standards:2C1396/C1396M Specification for Gypsum BoardD9 Terminology Relating to Wood and Wood-Based Prod-uctsD1038 Terminology Relating to Veneer and PlywoodD1554 Terminology Relating to Wood-Base Fiber and Par-ticle Panel MaterialsD4442 Test Methods for Direct Moisture Content Measure-ment of Wood and Wood-Base MaterialsD4444 Test Method for Laboratory Standardization andCalibration of Hand-Held Moisture MetersD7438 Practice for Field Calibration and Application ofHand-Held Moisture MetersE84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE176 Terminology of Fire StandardsE2404 Practice for Specimen Preparation and Mounting ofTextile,Paper or Polymeric(Including Vinyl)Wall orCeiling Coverings,and of Facings and Wood VeneersIntended to be Applied on Site Over a Wood Substrate,toAssess Surface Burning CharacteristicsIEEE/ASTM SI-10 International System of Units(SI):TheModern Metric System2.2CSA Standard:3CSA O121 Douglas Fir Plywood2.3 HPVA Standard:4ANSI/HPVA HP-1 American National Standard for Hard-wood and Decorative 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 April 1,2015.Published May 2015.Originallyapproved in 2007.Last previous edition approved in 2013 as E2579-13.DOI:10.1520/E2579-15.2For 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 Canadian Standards Association(CSA),178 Rexdale Blvd.,Toronto,ON Canada M9W 1R3.4Available from the Hardwood Plywood and Veneer Association,1825 MichaelFaraday Dr.,Reston,VA 20190.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.4NIST Standard:5Voluntary Product Standard PS 1-07 Structural Plywood3.Terminology3.1 DefinitionsFor definitions of terms used in this prac-tice refer to the terminology contained in Terminologies E176,D9,D1038,D1554,and ANSI/HPVA HP-1.4.Summary of Practice4.1 This practice describes procedures for specimenpreparation,mounting,and reporting,when testing woodproducts to assess flame spread and smoke development assurface burning characteristics using Test Method E84.5.Significance and Use5.1 Solid board,lumber and timber products(includingsolid boards,lumber,timber,fingerjoined lumber,glulam,laminate wood,laminated veneer lumber and parallel strandlumber products);panel products(including fibreboard,hardboard,oriented strandboard,wa
