Sets out methods for the determination of total moisture, free moisture and residual moisture in higher rank coal.

Scope

This Standard sets out methods for the determination of total moisture, free moisture and residual moisture in higher rank coal. The methods are as follows:
(a) Drying in air at ambient temperature for free moisture.
(b) Distillation (Method A), for residual or total moisture.
(c) Drying in nitrogen at 105–110°C (Method B), for residual or total moisture. (d) Drying in air at 105–110°C (Method C), for residual or total moisture.
Methods A and B are applicable to all higher rank coals. Method C is applicable only to higher rank coals that are known not to be susceptible to significant oxidation.
Where the sample is visibly wet, determination of residual moisture by Method A, B or C is preceded by the determination of free moisture.
NOTES:
1 A comparison of the ISO, BS, ASTM and AS Standard methods for determination of total moisture in coal and its parts is presented in Appendix A.
2 Options for sample preparation and determination of total moisture in accordance with this Standard are presented in a flowchart in Appendix B.
