INTRODUCTION
Coke, especially run of oven coke or foundry coke, or both, is a difficult material to sample. It is
imperative that every sample be collected and handled carefully and conscientiously and in strict
accordance with the standard procedure described herein.
Gross samples of not less than the quantities designated in this practice must be taken, whether the
coke to be sampled consists of a few tons or several hundred tons.
