Significance and Use4.1 This test method provides an indi
16、cation 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 home and laboratory results. The amount of dirtpicked up in the laboratory test may not b
17、e 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, carpets, dirt, and other factors (see Section 6).4.2 In order to provide a uniform basis
