1、Designation: F1409 16 An 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 cas
2、e 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, cani
3、ster, 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 te
4、sting 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 s
5、tandard. 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
6、 standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

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 du
9、ring 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 cl
10、eaner 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 d
11、esign 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
12、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 clea
13、ningoperation 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 of ASTM Committee F11 on Vac

Apparatus5.1 Mobility Equipment, to move the vacuum cleaner formeasuring and determining relative work. This equipment is tobe designed and developed by
18、 the user.5.2 Calibration WeightsPrecision weights for calibratingthe force measuring instrumentation. At least three calibrationweights shall be employed to check and ensure linear calibra-tion of the instrumentation. The precision weights are based onthe maximum rating of the load cell/strain gage
19、 that is used,and shall includea5lbweight, a half scale weight, and a fullscale weight.5.3 Test Carpets, as specified in Specification F655. Testcarpets shall be stored in a vertical position with no weight onthe test surface.NOTE 1The test carpets for relative work testing should be limited tothat
20、use and not used for other tests such as cleanability.5.4 Padding, beneath test carpet, as specified in Specifica-tion F655.5.5 Temperature and Humidity Indicators, to provide tem-perature measurements accurate to 61F (60.5C) and 62%relative humidity.5.6 Voltmeter, to measure input voltage to the va
21、cuumcleaner, capable of providing measurements accurate within61%.5.7 Voltage Regulator System, to control input voltage to thevacuum cleaner. The regulator system shall be capable ofmaintaining the vacuum cleaners rated voltage A, select an additional unitfrom the population and test, and repeat th
