Designation:E147414An American National StandardStandard Test Method forDetermining the Heat Release Rate of Upholstered Furnitureand Mattress Components or Composites Using a BenchScale Oxygen Consumption Calorimeter1This standard is issued under the fixed designation E1474;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.INTRODUCTIONThis test method provides a means for measuring the ignition time and heat release of the compositeupholstered components of upholstered furniture and mattresses using an oxygen consumptioncalorimeter.1.Scope1.1 This fire-test-response test method can be used todetermine the ignitability and heat release from the compositesof contract,institutional,or high-risk occupancy upholsteredfurniture or mattresses using a bench scale oxygen consump-tion calorimeter.1.2 This test method provides for measurement of the timeto sustained flaming,heat release rate,peak and total heatrelease,and effective heat of combustion at a constant initialtest heat flux of 35 kW/m2.This test method is also suitable toobtain heat release data at different heating fluxes.The speci-men is oriented horizontally,and a spark ignition source isused.1.3 The times to sustained flaming,heat release,and effec-tive heat of combustion are determined using the apparatus andprocedures described in Test Method E1354.1.4 The tests are performed on bench-scale specimenscombining the furniture or mattress outer layer components.Frame elements are not included.1.5 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.6 This standard is used to measure and describe theresponse of materials,products,or assemblies to heat andflame under controlled conditions,but does not by itselfincorporate all factors required for fire hazard or fire riskassessment of the materials,products,or assemblies underactual fire conditions.1.7 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 specificprecautionary statements,see Section 6.1.8 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD5865 Test Method for Gross Calorific Value of Coal andCokeE176 Terminology of Fire StandardsE603 Guide for Room Fire ExperimentsE906 Test Method for Heat and Visible Smoke ReleaseRates for Materials and Products Using a ThermopileMethodE1354 Test Method for Heat and Visible Smoke ReleaseRates for Materials and Products Using an Oxygen Con-sumption Calorimeter2.2 Other Documents:CA TB 133,Flammability Test Procedure for Seating Fur-niture for Use in Public Occupancies31This test method is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.21 on Smoke andCombustion Products.Current edition approved April 1,2014.Published May 2014.Originallyapproved in 1992.Last previous edition approved in 2010 as E1474-10.DOI:10.1520/E1474-14.2For 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 State of California,Dept.of Home Furnishings and ThermalInsulation,North Highlands,CA 95660-5595.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 ISO 5725 Part 2,Accuracy(Trueness and Precision)ofMeasurement Methods and ResultsBasic Method forthe Determination of Repeatability and Reproducibility ofa Standard Measurement Method43.Terminology3.1 Definitions:3.1.1 For definitions of terms relating to this test methodrefer to Terminology D123 and E176.3.1.2 effective heat of combustion,nthe amount of heatgenerated per unit mass lost by a material,product,orassembly,when exposed to specific fire test conditions.(seegross heat of combustion.)3.1.2.1 DiscussionThe effective heat of combustion de-pends on the test method and is determined by dividing themeasured heat release by the mass loss during a specifiedperiod of time under the specified test conditions.Typically,thespecified fire test conditions are provided by the specificationsof the fire test standard that cites effective heat of combustionas a quantity to be measured.For certain fire test conditions,involving very high heat and high oxygen concentrations underhigh pressure,the effective heat of combustion will approxi-mate the gr
