43、sspecified due to the historical usage of this method by furniture manufac-turers; and one by which they have accumulated much data which,reportedly, has correlated with end-use performance in certain cases.Nonetheless, Section 5 of Test Methods D 1175 states that the procedureis not recommended for

44、 acceptance testing. Consequently, the testrequirements for this performance factor should be used with caution, withthe knowledge that different fabrics will not always be ranked by this testin the same order as by actual abrasive wear which takes place on specificpieces of furniture.(a) The abrade
