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 divid
18、ed into a number of strips, thestrip being defined as the width of the power head or nozzle.For the purpose of this procedure, the cleaning area is specifiedas 10 m2(15 500 in.2), the stroke speed is defined as 0.5 60.03 m s (1.7 6 0.1 ft s), with a total of 10 strokes per strip.4.2 In order to prov
19、ide a uniform basis for measuring theperformance described in 1.1, standardized test carpets areemployed in this procedure.5. Apparatus5.1 Stopwatch, with a second hand or other type of equip-ment capable of establishing the specified rate of movementand total cycle time.5.2 Voltmeter, to measure in
20、put volts to the vacuum cleaner,to provide measurements accurate to within 61%.5.3 Wattmeter, to measure input watts to the vacuumcleaner, to provide measurements accurate to within 61%.5.4 Voltage-Regulator System, to control the input voltageto the vacuum cleaner. The regulator shall be capable of
21、maintaining the vacuum cleaners rated voltage 61 % andrated frequency having a wave form that is essentially sinusoi-dal with 3 % maximum harmonic distortion for the duration ofthe test.5.5 Data-Acquisition System, controlled in such a way that,depending on the movement of the agitator nozzle, at le
22、ast 10power measurements are recorded during each stroke.5.6 Temperature and Humidity Indicators, to provide tem-perature measurements accurate to within 612 C (61F) andhumidity measurements accurate to within 3 % relative humid-ity.5.7 Supporting SurfaceA flat surface consisting of a pieceof 19-mm
23、(34-in.) thick exterior grade plywood with the “A”surface upward to support the test carpet and pad. If necessary,the four corners (only) of the test carpet and pad may befastened to the supporting surface by any acceptable means.6. Materials6.1 Standard level loop or Wilton carpet conforming toSpec
24、ification F655.6.2 Standard carpet padding conforming to SpecificationF655.7. Sampling7.1 A minimum of three units of the same model vacuumcleaner selected at random in accordance with good statisticalpractice shall constitute the population sample.7.1.1 To determine the best estimate of energy usag
25、e asso-ciated with the population of the vacuum cleaner model beingtested, the arithmetic mean of the energy consumed by thesample from the population shall be established by testing it toa 90 % confidence level within 65 % of the mean value of theenergy usage rating.8. Conditioning8.1 Test RoomMain
26、tain the test room in which all condi-tioning and vacuum cleaner testing is performed at 21 6 3C(70 6 5F) and 45 to 55 % relative humidity.8.2 All components involved in the test shall remain and beexposed in the controlled environment for at least 16 h prior tothe start of the test.9. Procedure9.1
27、Test Procedure:9.1.1 The energy consumed by the sample vacuum cleanershall be established as follows:9.1.1.1 New test carpets and padding shall be level loop orWilton conforming to Specification F655.9.1.1.2 Supporting surface conforming to 5.7.9.1.1.3 Replace the carpet and padding when it has hole
28、s,tears, or other signs of wear.9.1.1.4 Speed shall be 0.5 6 0.03 m/s (1.7 6 0.1 ft/s).9.1.1.5 Use of automated methods are optional.9.1.2 Preparation of Test Vacuum Cleaners:9.1.2.1 New Test Vacuum Cleaners:(1) Change brush drive belt on vacuum cleaners or agitatornozzles using manufacturers instru
29、ctions, if equipped.(2) Run the vacuum cleaner in at rated voltage 61 % andrated frequency with filters in place.(3) In a stationary position, operate the vacuum cleaner for1 h with the agitator bristles not engaged on any surface.9.1.2.2 Used Test Vacuum CleanersRecondition a usedtest vacuum cleane
30、r, prior to each test run, as follows:(1) Thoroughly remove excess dirt from the vacuumcleaner. Without using tools for disassembly, clean the entireouter surface, brushes, nozzle chamber, ductwork, inside of thechamber surrounding the primary filter, all filters and insidehose and wands.(2) For vac
31、uum cleaners using disposable filters as theprimary filters, use a new disposable primary filter from themanufacturer for each test. Weigh the filter to the nearest 0.10g (0.0035 oz) and install it as recommended by the vacuumcleaner manufacturer.(3) For vacuum cleaners using non-disposable dirtrece
32、ptacles, empty in accordance with the manufacturersinstructions after each test run and clean the receptacle until itsweight is within 2 g (0.07 oz) of its original weight. Weigh thereceptacle to the nearest 0.10 g (0.0035 oz) and install it asrecommended by the vacuum cleaner manufacturer.NOTE 1Whi
33、le this procedure may be used by itself, there is a strongF2756 11 (2016)2likelihood that it will be used as a precursor for other performance testing.Therefore, it is considered reasonable to measure and record the initial bagor dirt cup weights prior to testing. If no additional testing is to beco
34、nducted, this step could be skipped.9.1.3 Test Vacuum Cleaner SettingsIf various settings areprovided, set the motor speed setting, suction regulator, nozzleheight, or combination thereof using the manufacturers speci-fications as provided in the instruction manual for the testcarpet being used. Con
35、tact the manufacturer if no instructionsare given, or if the instructions are unclear or inadequate.9.1.4 If the vacuum cleaner has not been energized for morethan 60 min prior to testing energize the cleaner for 5 min atnameplate rated voltage (61 %) and frequency (61 Hz)immediately preceding the t
36、est. For vacuum cleaners with dualnameplate voltage ratings, conduct testing at the highestvoltage.9.1.4.1 Place the vacuum cleaner agitator or nozzle agitator,if equipped, such that the bristles clear the supporting surfaceand no loose dirt is picked up.9.1.5 Immediately following the 5-min “run-in
37、” of 9.1.4,de-energize the vacuum cleaner and place the vacuum cleanernozzle on the test surface so that the front edge of the vacuumcleaner coincides with the line defining the beginning of thetest area.NOTE 2In the case of canister or wet/dry vacuum cleaners, the nozzleis attached at the end of a
38、hose and wand. It will be the nozzle intendedfor use on carpet. For combination tools, it will be set for carpet cleaning.9.1.5.1 If an automated method is not used, reasonableefforts shall be made to maintain the handle height at 800 mm(31.5 in.) during each test run for vacuum cleaners with apivot
39、ing handle.9.1.6 Measure the power consumed while vacuuming carpetwith either of the methods defined in IEC 60312, clause 4.14 orUL 1017, clause 5.2, as modified below.9.1.6.1 Operate the vacuum cleaner or nozzle (with orwithout agitator) for a period of 2 min back and forth on thetest carpet.9.1.6.
40、2 Take power measurements during the last minute,with a minimum of five measurements in each stroke directionaveraging the readings to determine the mean power, PAVG,consumed.NOTE 3The IEC 60312 test method includes the transition areas at theend of each stroke. There is no evidence indicating that
41、including orexcluding the transition areas has any significant effect on the results.9.1.7 Using the same test vacuum cleaner, repeat 9.1.3 9.1.6 two additional times for a total of three test runs.9.1.8 The average energy used for each individual testvacuum cleaner from the population sample for a
42、given carpetis the average of three test runs meeting the repeatabilitystatement in Section 11.9.1.9 The energy, Joules (W-s), consumed by the samplevacuum cleaner cleaning a 10 m2area with ten total cleaningstrokes per strip is calculated with the following equation:E 5 PAVG3N 3A/b 31023v! Joules W
43、 2 s!

44、e result is:E 5 PAVG38 310/b 3102330. 5!5 PAVG316 3104/b5 16 31043PAVG/b (2)NOTE 4A complete derivation of the equation may be found in IEC60312.9.1.10 Aminimum of two additional test sample units of thesame model shall be selected in accordance with the samplingstatement of Section 7. Repeat 9.1.1
45、9.1.9 for each new testsample unit selected.10.
