Designation:F55813An American National StandardStandard Test Method forMeasuring Air Performance Characteristics of VacuumCleaners1This standard is issued under the fixed designation F558;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers procedures for determining airperformance characteristics of commercial and householdupright,canister,stick,hand-held,utility,and combination-type vacuum cleaners having provisions for attaching a hoseand incorporating a series universal motor.This test methodcan be applied to the carpet cleaning mode of operation.1.2 These tests and calculations include determination ofsuction,airflow,air power,maximum air power,and inputpower under standard operating conditions(see Note 1).Thenozzle mounted on plenum testing is an ideal air performancemeasurement and is not intended to represent the actual airperformance during carpet or floor cleaning.NOTE1For more information on air performance characteristics,seeRefs(1-6).21.3 The foot-pound-inch system of units is used in thisstandard.The values in parentheses are given for informationonly.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.Aspecific precautionary statement is given in Note 2.2.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,the net timerate of work performed by an air stream while expendingenergy to produce an airflow by a vacuum cleaner underspecified air resistance conditions.3.1.2 automatic bleed valve,nany device a part of avacuum cleaners design which automatically introduces anintentional leak within the vacuum cleaners system whenmanufacturer specified conditions are met.3.1.3 corrected airflow,Q,cfm,nin a vacuum cleaner,thevolume of air movement per unit of time under standardatmospheric conditions.3.1.4 input power,W,nthe rate at which electrical energyis absorbed by a vacuum cleaner.3.1.5 model,nthe designation of a group of vacuumcleaners having the same mechanical and electrical construc-tion with only cosmetic or nonfunctional differences.3.1.6 population,nthe total of all units of a particularmodel vacuum cleaner being tested.3.1.7 repeatability limit(r),nthe value below which theabsolute difference between two individual test results obtained1This 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 May 1,2013.Published June 2013.Originallyapproved in 1978.Last previous edition approved in 2011 as F558 11.DOI:10.1520/F0558-13.2The 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 fromAir Movement and ControlAssociation,30 West University Dr.,Arlington Heights,IL,60004.5Available from the IEC Web store,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 under repeatability condition may be expected to occur with aprobability of approximately 0.95(95%).3.1.8 repeatability standard deviation(Sr),nthe standarddeviation of test results obtained under repeatability condi-tions.3.1.9 reproducibility limit(R),nthe value below which theabsolute difference between two test results obtained underreproducibility conditions may be expected to occur with aprobability of approximately 0.95(95%).3.1.10 reproducibility standard deviation(SR),nthe stan-dard deviation of test results obtained under reproducibilityconditions.3.1.11 sample,na group of vacuum cleaners ta
