The question I have is this: Per AMS2431/2 paragraph 3.9.1 when testing shot the machine should rotate and tap for 5 minutes for sieves 30 mesh and coarser and for 10 minutes for sieves finer than 30 mesh. The sieves for 70 and 110 are all finer than 30 mesh, 3 of the sieves for 170 are finer than 30 mesh, and 1 sieve for 230 is finer than 30 mesh. How much time should be used when checking 170 and 230 shot?
