• Mechanical Sampling System Mechanical sampling of coal produces the most representative and repeatable sampling data, according to ISO and ASTM requirements, that is why mechanical sampling is favoured to manual sampling. The risk of incorrect sample findings is reduced where a well-designed and built mechanical sampling system is used.
