8、 Method for Determining A-Weighted SoundPower Level of Vacuum Cleaners2.2 ASTM Adjunct:3Mobility fixture book3. Summary of Test Method3.1 The carpet cleaning mechanism of the vacuum cleaner ismoved back and forth on the test carpet in a prescribed mannerduring the test. A handle clamp assembly with

9、a strain gage isattached to the vacuum cleaner at the location where the usersworking hand usually grips the carpet cleaning mechanism.This gage measures the force involved in moving only thecarpet cleaning mechanism.3.2 Simultaneously, by means of a rod pivotally mounted tothe test fixture, the dis

10、tance that the vacuum cleaner moves ismonitored. The force and distance signals are then introducedinto an X-Y recorder that produces a plot from which relativework is determined. Alternate data acquisition and computingmethods are acceptable.4. Significance and Use4.1 This test method measures the

11、relative work required bythe user during the cleaning operation for the movement of avacuum cleaner in the home or other cleaning location.Relative work is defined as the work measured by the equip-ment described in this test method.4.2 This measurement is relative to the work performed bythe user o
