ASTM E877-21 PDF Download

A standard process called ASTM E877-21 describes how to sample iron ores and related materials mechanically. The technique uses both stopped-belt sampling and falling stream sampling. This standard's goal is to give instructions on how to sample and prepare the gross sample for the numerous test samples needed to ascertain the materials' chemical make-up and physical characteristics.

Three annexes are also included in the scope of ASTM E877-21. Design standards are provided in the first annexe to guarantee the objectivity of the sampling procedure. The second annexe goes on to discuss statistical techniques for figuring out how precisely sampling and division are done as well as quality variation. The third annexe outlines a technique for contrasting two sampling techniques to find any potential systematic variations.
