These parameters may affect the lot’s value, its ability to meet specifications, its environmental impact, as well as other properties. For the sampling of coal using mechanical sampling systems see D Practice for the Mechanical Sampling of Coal.
If a true lot is larger than 1, tons, sampling increments are either increased proportionately, or the total quantity is subdivided and each sub-lot is sampled individually.
ASTM D / DM – 02 Standard Practice for Collection of a Gross Sample of Coal
Because of the variability of coal and the wide variety of sampling equipment, caution should be used in all stages of sampling from system specifications and equipment procurement to equipment acceptance testing and actually taking the final sample. As is often the case, however, this matter is neither simple nor straightforward. Need more than one copy?

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. ASTM D prescribes how the gross sample is to be ground, mixed, and divided using milling and rifling equipment rifling is a type of sorting process to yield a quantity that remains representative of the whole, while being suitable in size for analysis.
The simple matter of gathering a sample of coal and sending it to the laboratory now has become quite an arduous procedure requiring some sophisticated and specialized apparatus—apparatus that many facilities may not have access to.
While 40 CFR Part 98 does not specifically prescribe the above sampling and preparation methods, it names no alternative protocol either.
