New cast steel shot is tested by performing a sieve analysis on a Ro-Tap (i.e. SAE J444 or AMS 2431/1,2). A Ro-Tap is a device which shakes and taps test sieves. New cut wire media is typically tested by the measurement and precision weighing a sample (i.e. SAE J442 or AMS 2431/3,4, and 8). In-process media (media being used in a machine) is typically inspected by performing a sieve analysis with a Ro-Tap.
