-Transfer to sample container w/out loss
-Repeat until sample size is obtained
-Combine to form full sample
Explain the procedure for sampling from conveyor belts - CORRECT ANSWERS -avoid
the beginning or end
-stop the belt
-place sampling template through the mix on the belt
-remove mix from inside the template, including all fines and place in container
