Designation:F140916An American National StandardStandard Test Method forStraight Line Movement of Vacuum Cleaners While CleaningCarpets1This standard is issued under the fixed designation F1409;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 a measurement of the relativework required to move an upright,canister,stick,or combina-tion vacuum cleaner in a straight line with forward andbackward stroking on a selection of typical carpeted surfaces.1.1.1 This test method measures only the horizontal com-ponent of work required to move the vacuum cleaner on carpet.1.2 This test method can be used in the testing of householdand commercial vacuum cleaners.1.3 This test method measures the relative work needed tomove the vacuum cleaner with its motor or motors in opera-tion.1.4 This test method applies to the vacuum cleaning ofcarpets only.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 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:2F608 Test Method for Evaluation of Carpet Embedded DirtRemovalEffectivenessofHousehold/CommercialVacuum CleanersF655 Specification for Test Carpets and Pads for VacuumCleaner TestingF884 Test Method for Motor Life Evaluation of a Built-In(Central Vacuum)Vacuum CleanerF922 Test Method for Motor Life Evaluation of an ElectricMotorized NozzleF1038 Test Method for Motor Life Evaluation of a Canister,Hand-held,Stick,and Utility Type Vacuum Cleaner With-out a Driven AgitatorF1334 Test Method for Determining A-Weighted SoundPower Level of Vacuum Cleaners3.Summary of Test Method3.1 Mobility equipment is to be constructed and used topush the vacuum cleaner back and forth on the test carpet in aprescribed manner during the test.The mobility equipment isto employ a handle clamp assembly with a strain gage,to beattached to the vacuum cleaner handle.This strain gagemeasures the horizontal forces involved in moving only thevacuum on the test carpet.3.2 Simultaneously,the incremental distance that thevacuum cleaner moves is also monitored and collected.Theforce and distance measurements are then used for calculatingthe work required to push and pull the vacuum on the testcarpet.3.3 The design of the mobility equipment used in thismethod is left to the user to develop and construct as there arenumerous design approaches that may be employed for thisevaluation.The mobility equipment may be designed to movethe vacuum automatically or manually.Photographs of onedesign used in the industry to move the vacuum without theassistance of a technician is provided in Figs.1-3.It is highlyrecommended that data acquisition and computerization,with adata sampling rate of at least ten samples per second,beutilized to improve the speed and accuracy of data measure-ments.4.Significance and Use4.1 This test method measures the horizontal component ofthe relative work required by the user during the cleaningoperation for the movement of a vacuum cleaner in the homeor other cleaning location on standardized laboratory carpeting.Work is determined from the forces measured in the horizontaldirection only by the mobility equipment.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 Nov.1,2016.Published December 2016.Originallyapproved in 1992.Last previous edition approved in 2010 as F1409 00(2010).DOI:10.1520/F1409-16.2For 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 4.2 This measurement is relative to the work performed bythe user of vacuum cleaners and may be used for comparisonbetween vacuum cleaners.4.3 The relation between actual vacuum cleaner usage andthe method of operation is valid only if the vacuum cleaneruser operates the vacuum cleaner properly and in accordancewith the manufacturers instructions.FIG.1 ASTM Mobility EquipmentFIG.2 Strain Gage and Handle ClampF1409 162 5.Apparatus5.1 Mobility Equipment,to move the vacuum cleaner formeasuring and determining relative work.This eq
