17、aner of the model beingtested.4. Significance and Use4.1 This test method provides an indication of the capabilityof the vacuum cleaner to remove embedded dirt from carpet-ing. This test method is based upon results of home cleaningtests so that, in most cases, a reasonable correlation existsbetween
18、 home and laboratory results. The amount of dirtpicked up in the laboratory test may not be the same as in thehome; however, it will show that, in most cases, a vacuumcleaner that performs well in the laboratory will perform wellin a home. Laboratory results may differ due to variations inthe homes,
19、 carpets, dirt, and other factors (see Section 6).4.2 In order to provide a uniform basis for measuring theperformance described in 1.1, standardized test carpets and astandardized test dirt are employed in this procedure.5.
