16、the falling abrasive values in Test Method D968.5.2 For some materials,abrasion tests utilizing the TaberAbraser may be subject to variation due to changes in theabrasive characteristics of the wheel during testing.Dependingon abradant type and test specimen,the wheel surface maychange(that is,become clogged)due to the adhesion of debrisgenerated during the test and must be resurfaced at morefrequent intervals as agreed upon by the interested parties.Todetermine if more frequent resurfacing is r
