Designation:E217903(Reapproved 2009)Standard Test Method forLaboratory Measurement of the Effectiveness of FloorCoverings in Reducing Impact Sound TransmissionThrough Concrete Floors1This standard is issued under the fixed designation E2179;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 is part of a set for evaluating the sound-insulating properties of building elements.It is designed to measure the reduction in transmission of impact sound due to a floor covering in alaboratory.Others in the set include the measurement of sound isolation in buildings(Test MethodE336),the laboratory methods of measuring airborne sound transmisssion loss of building partitionssuch as walls,floor-ceiling assemblies,doors,and other space-dividing elements(Test Method E90);the laboratory measurement of impact sound transmission through floors(Test Method E492),themeasurement of impact sound transmission in buildings(Test Method E1007),the measurement ofsound transmission through building facades and facade elements(Guide E966),and the measure-ment of sound transmission through a common plenum between two rooms(Method E1414).1.Scope1.1 This test method describes a method for the laboratorymeasurement of the effectiveness of floor coverings in reducingimpact noise from a standard tapping machine through con-crete floors.The test results are not necessarily directly relatedto the subjective evaluations of the floor coverings.1.2 This test method applies to all floor coverings,whethersingle or multi-layered,as installed on a standard concretefloor.Multi-layered coverings may be factory-assembled orassembled at the test laboratory.1.3 The test method applies only to laboratory measure-ments.It does not apply to the measurement of the effective-ness of a floor covering in a field situation.1.4 Laboratory AccreditationA procedure for accreditinga laboratory for performing this test method is given in MethodE492.1.5 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.2.Referenced Documents2.1 ASTM Standards:2C634 Terminology Relating to Building and EnvironmentalAcousticsE90 Test Method for Laboratory Measurement of AirborneSound Transmission Loss of Building Partitions andElementsE336 Test Method for Measurement of Airborne SoundAttenuation between Rooms in BuildingsE492 Test Method for Laboratory Measurement of ImpactSound Transmission Through Floor-Ceiling AssembliesUsing the Tapping MachineE966 Guide for Field Measurements of Airborne SoundAttenuation of Building Facades and Facade ElementsE989 Classification for Determination of Impact InsulationClass(IIC)E1007 Test Method for Field Measurement of TappingMachine Impact Sound Transmission Through Floor-Ceiling Assemblies and Associated Support StructuresE1414 Test Method for Airborne Sound Attenuation Be-tween Rooms Sharing a Common Ceiling Plenum2.2 ANSI Standards:S1.6 Standard Preferred Frequencies,Frequency Levels,andBand Numbers for Acoustical Measurements1This test method is under the jurisdiction ofASTM Committee E33 on Buildingand Environmental Acoustics and is the direct responsibility of SubcommitteeE33.03 on Sound Transmission.Current edition approved April 1,2009.Published August 2009.Originallyapproved in 2001.Last previous edition approved in 2003 as E2179 032.DOI:10.1520/E2179-03R09.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 S1.10 Pressure Calibration of Laboratory Standard PressureMicrophonesS1.11 Specification for Octave-band and Fractional-Octave-Band Analog and Digital Filters2.3 ISO Standards:ISO 717-2 Rating of Sound Insulation in Buildings and ofBuilding ElementsPart 2:Impact Sound InsulationISO 140-6 AcousticsMeasurement of Sound Insulation inBuildings and of Building ElementsPart 6:LaboratoryMeasurements of Impact Sound Insulation of FloorsISO 140-8 Acoustics Measurement of Sound Insulation inBuildings and of Building ElementsPart 8:LaboratoryMeasurements of the Reduction of Transmitted ImpactNoise by Floor Coverings on a Heavyweight Floor3.Terminology3.1 Definitions of the acoustical terms used in this testmethod are given in Terminology C634.3.2 Definitions of Terms Specific to This Standard:3.2.1 floor coveringany resilient material,combination ofresilient materials or
