Designation:F210511An American National StandardStandard Test Method forMeasuring Air Performance Characteristics of VacuumCleaner Motor/Fan Systems1This standard is issued under the fixed designation F2105;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 test method covers procedures for determining airperformance characteristics of series universal motor/fan sys-tems used in commercial and household upright,canister,stick,hand-held utility,combination-type vacuum cleaners,andhousehold central vacuum cleaning systems.1.2 These tests and calculations include determination ofsuction,airflow,air power,maximum air power,and inputpower under specified operating conditions.NOTE1For more information on air performance characteristics,seeReferences(1)through(2).21.3 The values stated in inch-pound units are to be regardedas the standard.The values given in parentheses are forinformation only.1.4 This standard may involve hazardous materials,operations,and equipment.This standard does not purport toaddress all of the safety concerns,if any,associated with itsuse.It is the responsibility of the user of this standard toestablish appropriate safety and health practices and deter-mine the applicability of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:3E1 Specification for ASTM Liquid-in-Glass ThermometersE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE2251 Specification for Liquid-in-Glass ASTM Thermom-eters with Low-Hazard Precision LiquidsF431 Specification for Air Performance Measurement Ple-num Chamber for Vacuum Cleaners2.2 AMCA Standard:4210-85 Laboratory Methods of Testing Fans for Rating2.3 IEC Standard:5IEC 60312 Ed 3.2 Vacuum Cleaners for Household UseMethods of Measuring the Performance3.Terminology3.1 Definitions:3.1.1 air power,AP,W,nin a vacuum cleaner motor/fansystem,the net time rate of work performed by an air streamwhile expending energy to produce an airflow by a vacuumcleaner motor/fan system under specified air resistance condi-tions.3.1.2 corrected airflow,Q,cfm,nin a vacuum cleanermotor/fan system,the volume of air movement per unit of timeunder standard atmospheric conditions.3.1.3 input power,W,nrate at which electrical energy isabsorbed by a vacuum cleaner motor/fan system.3.1.4 model,ndesignation of a group of vacuum cleanermotor/fan systems having the same mechanical and electricalconstruction.3.1.5 population,ntotal of all units of a particular modelvacuum cleaner motor/fan system being tested.3.1.6 repeatability limit(r),nvalue below which theabsolute difference between two individual test results obtainedunder repeatability condition may be expected to occur with aprobability of approximately 0.95(95%).3.1.7 repeatability standard deviation(Sr),nstandard de-viation of test results obtained under repeatability conditions.3.1.8 reproducibility limit(R),nvalue below which theabsolute difference between two test results obtained underreproducibility conditions may be expected to occur with aprobability of approximately 0.95(95%).1This test method is under the jurisdiction ofASTM Committee F11 on VacuumCleaners and is the direct responsibility of Subcommittee F11.22 on Air Perfor-mance.Current edition approved Nov.1,2011.Published December 2011.Originallyapproved in 2001.Last previous edition approved in 2006 as F2105 06.DOI:10.1520/F2105-11.2The boldface numbers in parentheses refer to the list of references appended tothis test method.3For 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.4Available from Air Movement and Control Association,Inc.,30 West Univer-sity Dr.,Arlington Heights,IL 60004-1893.5Available from the IEC webstore,webstore.iec.ch,or American NationalStandards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.9 reproducibility standard deviation(SR),nstandarddeviation of test results obtained under reproducibility condi-tions.3.1.10 sample,ngroup of vacuum cleaner motor/fan sys-tems taken from a large collection of vacuum cleaner motor/fansystems of one particular model which serves to provideinformation that may be used as a basis for making a decisionconcerning the larger collection.3.1.11 standard air density,std,lb/ft3,natmospheric airdensity of 0.075 lb/ft3(1.2014 kg/m3).3.1.11.1 DiscussionThis value of air density correspondsto atmospheric air at a temperature of 68F(
