7、s of Terms Specific to This Standard:3.2.1 doorany sliding,folding,rolling,lifting,swingingor dropping partition that provides access and can be manuallyor automatically opened and closed.3.2.2 door panelthe component of the door system thatconstitutes a movable barrier without accessories:that is,t
8、heportion of a door system which may be tested as a fixed panel(room divider).The term door panel may be used in the reportas part of the description of the designated door system(forexample,door panel construction).3.2.3 door systemthe combined assembly of the compo-nents designated by or provided
9、by the test sponsor whichenables a fully operable door panel to function in normalmanner while fulfilling its intended purpose.The door systemshall include a jamb,threshold/plate/finished floor,lockset/latch/deadbolt,knob/lever/handle,hinges/rollers/guides,stops,panel/barrier/partition,strike plate,
10、hardware,and seals(fixed,automatic,pneumatic,magnetic,or manually adjustable).Thesystem may include mail slots,vision lights,security devices,bells,buzzers,chimes,knockers,door closures,vents,andadd-on panels.3.2.4 multiple doorstwo or more doors mounted side byside(in a single vertical plane),with
11、a common astragal ormullion;or two or more doors mounted in tandem a series ofvertical planes with intermediate airspace(s).3.2.5 operable and fixed sealsthe combined assembly ofcomponents intended to minimize the passage of air,light,orwater through or around the door panel and frame assembly.The s
12、eals may also perform other functions such as controllingeffects of chemical,thermal,blast,security,hydraulics,meter-ology,radio frequency interference(RFI)or electro magneticinterference(EMI);however,for this test method,only thereduction of airborne sound transmission shall be evaluated.4.Summary
13、of Test Method4.1 After the complete door system is installed and all finaladjustments are completed,the force or torque to open and toclose the door shall be measured during the operable test(seeSection 7).Subsequently the sound transmission loss of thedoor system shall be tested for two conditions
14、 in any order ofpreference:a fully operable door and a sealed panel(seeSection 6).1This test method is under the jurisdiction of ASTM Committee E-33 onEnvironmentalAcoustics and is the direct responsibility of Subcommittee E33.03 onSound Transmission.Current edition approved May 8,1991.Published Jul

16、used for three purposes:the labora-tory measurement of(1)the sound transmission loss of fullyoperable doors equipped with a particular combination ofhardware and seals,(2)the sound transmission loss of alaboratory sealed door panel and(3)the force or torquerequired to operate the door system.5.2 This test method relies upon Test Method E 90 foracoustical testing,and all requirements in that standard,includ-ing Annex A2(Laboratory Accreditation).Also see 6.1 foradditional references and requireme
