Designation:F55501(Reapproved 2011)An American National StandardStandard Test Method forMotor Life Evaluation of an Upright Vacuum Cleaner1This standard is issued under the fixed designation F555;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 motor life evaluation of house-hold or commercial single and dual motor upright vacuumcleaners(uprights with separate motors for creating thevacuum and driving the floor brush).Self-propelled or power-assist cleaners are not within the scope of this test method.1.2 This test method is limited to evaluation of the uprightvacuum cleaner electric motor(s).1.3 This test method provides a test to determine operatinglife of the motor(s),before servicing is needed,by an acceler-ated laboratory procedure.Motor(s)are tested while mountedand operated in the upright vacuum cleaner.1.4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units,which are provided for informationonly and are not considered standard.1.5 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:2D75 Practice for Sampling AggregatesE337 Test Method for Measuring Humidity with a Psy-chrometer(the Measurement of Wet-and Dry-Bulb Tem-peratures)F431 Specification for Air Performance Measurement Ple-num Chamber for Vacuum CleanersF608 Test Method for Evaluation of Carpet Embedded DirtRemovalEffectivenessofHousehold/CommercialVacuum CleanersF655 Specification for Test Carpets and Pads for VacuumCleaner Testing3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 motor lifelimited by failure of motor.Failure ismotor stoppage.In the case of a dual motor upright,the testwill be continued until both motors(vacuum motor and floorbrush motor)have failed.The motor that fails first will bereplaced so that the test may continue on the other motor.Themotor life of each motor will be recorded separately.3.1.1.1 DiscussionAny failure integral with the motor,such as armature assembly,field assembly,housing(s),bearings,motor cooling fan or primary air moving fan,brushassemblies,motor mounted nonresettable thermal protectiondevices,or any other component judged to be integral with themotor,shall be judged as motor stoppage.4.Significance and Use4.1 The test results provide an indication of the motor life ofan electric upright vacuum cleaner.End of motor life will bejudged in accordance with Section 3.5.Apparatus and Materials5.1 Voltage Regulator System,to control the input voltage tothe vacuum cleaner.The regulator system shall be capable ofmaintaining the vacuum cleaners rated voltage 61%andrated frequency 61 Hz having a wave form that is essentiallysinusoidal with 3%maximum harmonic distortion for theduration of the test.5.2 Voltmeter,to provide measurements accurate to within61%.5.3 Timer and Switch,having the capacity to control theoff/on duty cycle of the cleaner during the life test.5.4 Sharp Edge Orifice Platea 114-in.(32-mm)diameterorifice shall be in accordance with Fig.2 of Specification F431.5.5 Wattmeter,to provide measurements accurate to within1%.5.6 Plenum Chamber,conforming to the plenum chamberdescribed in Specification F431.5.7 Water Manometer,or equivalent instrument measuringin increments of 0.1 in.(2.54 mm).1This test method is under the jurisdiction ofASTM Committee F11 on VacuumCleaners and is the direct responsibility of Subcommittee F11.30 on Durability-Reliability.Current edition approved Nov.1,2011.Published March 2012.Originallyapproved in 1985.Last previous edition approved in 2006 as F555 01(2006).DOI:10.1520/F0555-01R11.2For 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 5.8 Barometer,to provide measurements accurate to 60.05in.Hg(1.27 mm Hg),with scale divisions 0.02 in.(0.51 mm)or finer.5.9 Thermometer,having a range of at least 18 to 80F(8to+27C)and graduated in 1F(0.5C)increments.5.10 Psychrometer,meeting the requirements of TestMethod E337 for thermometers graduated in increments of 1F(0.5C).5.11 Test Carpet,conforming to the level loop carpetdescribed in Specification F655.A carpet that provides equiva-lent nozzle loading results may be used.5.12 Carpet Padding(optional),if
