Active Standard: E18 - 12
Currently there are no requirements defining how to verify indenters that, because of their shape, cannot perform tests using the Rockwell scales normally called out for verification. This,for example,applies to side cut diamonds that cant, because of their shape, support HRC scale forces and thin tip ball indenters that cant support HRB scale test forces. This revision will define how to verify those indenters.
