Steam Coal Specification

Our Steam Coal Specification

The gross samples were collected during barges supply and vessel loading operation at their port of loading for Total Moisture. Size Analysis and General Analysis purpose according to the ASTM Standard Method. To obtain Total Moisture result, the gross samples were collected during discharging from the barge deck into the above mentioned vessel.

The Collected samples were prepared and analyzed in accordance to ASTM Standard Methods and showed the following average results :
