Designation:F275611An American National StandardStandard Test Method forDetermining Energy Consumption of Vacuum Cleaners1This standard is issued under the fixed designation F2756;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 only a laboratory test fordetermining the energy usage-of household and commercialupright,canister,stick,and wet/dry vacuum cleaners operatingon carpet when tested under specified conditions.1.1.1 This procedure may be used in conjunction with otherperformance criteria,such as cleaning effectiveness.1.1.2 Vacuum cleaners,other than upright vacuum cleaners,that provide a carpet-cleaning function are tested in accordancewith the carpet-cleaning instructions provided in the manufac-turers instruction manual.If the manufacturers instructionmanual does not contain instructions for a carpet-cleaningfunction,the vacuum cleaner is not within the scope of thisprocedure.1.2 This test method is applicable to household and com-mercial types of vacuum cleaners.1.3 The values stated in SI units are to be regarded asstandard.The inch-pound units given in parentheses aremathematical conversions that are provided for informationonly and are not considered standard.1.4 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:2F655 Specification for Test Carpets and Pads for VacuumCleaner Testing2.2 Other Standards:IEC 60312 Vacuum cleaners for household use-Methods ofmeasuring the performance,Fourth Edition3UL 1017 Vacuum Cleaners,Blower Cleaners,and House-hold Floor Finishing Machines43.Terminology3.1 Definitions:3.1.1 energy usage,namount of electrical energy con-sumed by a vacuum cleaner during cleaning,measured inJoules(Watt-seconds).There are 3600 watt-seconds in onewatt-hour.3.1.2 model,ndesignation of a group of vacuum cleanershaving identical mechanical and electrical construction withonly cosmetic or nonfunctional differences.3.1.3 population,ntotal of all units of a particular modelvacuum cleaner being tested.3.1.4 repeatability limit,r,nvalue below which the abso-lute difference between two individual test results obtainedunder repeatability condition may be expected to occur with aprobability of approximately 0.95(95%).3.1.5 repeatability standard deviation,Sr,nstandard de-viation of test results obtained under repeatability conditions.3.1.6 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%).3.1.7 reproducibility standard deviation,SR,nstandarddeviation of test results obtained under reproducibility condi-tions.3.1.8 sample,ngroup of vacuum cleaners taken from alarge collection of vacuum cleaners of one particular modelwhich serves to provide information that may be used as a basisfor making a decision concerning the larger collection.3.1.9 strip,nwidth covered during one stroke,defined bythe extreme outside geometric width of the power head ornozzle.1This test method is under the jurisdiction ofASTM Committee F11 on VacuumCleaners and is the direct responsibility of Subcommittee F11.20 on Performance(Test Methods).Current edition approved June 1,2011.Published July 2011.Originally approvedin 2009.Last previous edition approved in 2009 as F2756 09.DOI:10.1520/F2756-11.2For 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.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.4Available from Underwriters Laboratories(UL),333 Pfingsten Rd.,Northbrook,IL 60062-2096,http:/.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.10 test run,ndefinitive procedure that produces asingular measured result.3.1.11 unit,nsingle vacuum cleaner of the model beingtested.3.1.12 watt-hour meter,nmeter that measures and regis-ters the integral,with respect to time,of the active power of thecircuit in which it is connected;the unit of measurement isusually the kilowatt-hour.4.Significance and Use4.1 This test method provides an indication of the amount ofenergy usage of the vacuum cleaner while operating over aspecified cleaning area at a specified stroke speed and totalnumber of cleaning strokes.4.1.1 The test area is divided int
