18、carpeting.This test method is based upon results of home cleaning tests so that, in most cases, a reasonable correlation exists between homeand laboratory results. The amount of dirt picked up in the laboratory test may not be the same as in the home; however, it willshow that, in most cases, a vacu

19、um cleaner that performs well in the laboratory will perform well in a home. Laboratory resultsmay differ due to variations in the homes, carpets, dirt, and other factors (see Section 6).4.2 In order to provide a uniform basis for measuring the performance described in 1.1, standardized test carpets
