The new abrasive is currrently moreaggressive, resulting in

21、lower abrasive hardness values (Ha) than when the standard was initially established. As such, care should be taken when interpreting Havaluesfrom tests using the new abrasive, particularly with regard to currentASTM stone standard specification requirements for abrasion resistance, which were devel

22、oped whenthe original abrasive was still in use. Committee C18 is actively studying alternatives to address this issue.CAbrasion Resistance Test Method C 1353 will eventually replace Test Method C 241 and it is not necessary to perform both tests. Availability of the proper equipmentand materials by the testing laboratory may determine which test is performed.C629082
