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 s

17、peed and totalnumber of cleaning strokes.4.1.1 The test area is divided 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 m (15 500 in.), the stroke speed is defined as 0.5 60.03 m/s (1.7 6

18、0.1 ft/s), with a total of 8 strokes per strip.4.2 In order to provide a uniform basis for measuring theperformance described in 1.1, standardized test carpets areemployed in this procedure.5.

The regulator shall be capable ofmaintaining 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

21、 a way that,depending on the movement of the agitator nozzle, at least 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.

22、5.7 Supporting SurfaceA flat surface consisting of a pieceof 19-mm (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.

29、 For vacuum cleaners with non-disposable dirt recep-tacles, weigh and record the receptacles original weight to thenearest 0.10 g (0.0035 oz).9.1.2.2 Used Test Vacuum CleanersRecondition a usedtest vacuum cleaner, prior to each test run, as follows:(1) Thoroughly remove excess dirt from the vacuumcl

30、eaner. 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.9.1.3 Test Vacuum Cleaner SettingsIf various settings areprovided, set the motor speed setting, suct

31、ion regulator, nozzleheight, or combination thereof using the manufacturers speci-fications as provided in the instruction manual for the testcarpet being used. Contact the manufacturer if no instructionsare given, or if the instructions are unclear or inadequate.9.1.4 If the vacuum cleaner has not

32、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 test. For vacuum cleaners with dualnameplate voltage ratings, conduct testing at the highestvoltage.9.1.4.1 Place the vacuum cleaner agit
