Designation:E296414Standard Test Method forMeasurement of the Normalized Insertion Loss of Doors1This standard is issued under the fixed designation E2964;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 of standards for evaluating the sound-insulating properties ofbuilding elements and the sound isolation between spaces.It is designed to measure the field soundisolation performance of doors.Others in the set cover the airborne sound transmission loss of anisolated partition element in a controlled laboratory environment(Test Method E90),field measure-ments of the sound isolation between rooms in buildings(Test Method E336),the laboratorymeasurement of impact sound transmission through floors(Test Method E492),the measurement ofimpact sound transmission in buildings(Test Method E1007),the measurement of sound transmissionthrough building facades and facade elements(Guide E966),and the measurement of soundtransmission through a common plenum between two rooms(Test Method E1414).1.Scope1.1 The sound insulation properties of a door are measuredin a laboratory as the sound transmission loss in accordancewith Test Method E90.Using those data single number ratingsound transmission class(STC)is assigned.In the field,therooms on one or both sides of a partition containing a door areoften either too small or too large and absorptive to allow theapparent transmission loss(ATL)of the partition-door assem-bly to be measured.Even if that is not the case,the resultmeasured is the composite ATL of the partition including thedoor,and not that of the door itself.Test Method E336 actuallystates that it is impossible to measure the ATL of a portion ofa partition such as a door according to the procedures of thatstandard.This test method provides a method of evaluatingdoors in such cases using a normalized insertion loss with aresulting single number rating door transmission class,DTC.This method is intended primarily for hinged personnel doorswith latching mechanisms and is limited to door openings ofarea less than 6 m2.The flanking effects of surroundingstructure are reduced compared to E336 but not completelyeliminated.In a laboratory environment,the DTC is close to orequal to the STC of the door,but in the field results less thanthe laboratory STC should be expected.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 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 BuildingsE413 Classification for Rating Sound InsulationE492 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 ElementsE1007 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 Plenum1This 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 June 1,2014.Published July 2014.DOI:10.1520/E2964-14.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.2 ANSI Standards:3S1.4 Specification for Sound Level MetersS1.10 Pressure Calibration of Laboratory Standard PressureMicrophonesS1.11 Specification for Octave-Band and Fractional-Octave-Band Analog and Digital FiltersS1.40 Specification and Verification Procedures for SoundCalibrators2.3 IEC Standards:4IEC 60804 Specification for Integrating-Averaging SoundLevel MetersIEC 60942 ElectroacousticsSound Calibrators2.4 ISO Standard:5ISO 16283-1:2014 Acoustics-Field measurement of soundinsulation in buildings and of building elements-Part 1:Airborne sound insulation3.Terminology3
