What is ISO 1018-Determination of moisture-holding capacity of hard coal about?
ISO 1018 is a standard that covers technical specifications for the determination of moisture-holding capacity which enables classification for correcting the calorific value of the sample to the moist mineral matter-free basis.
ISO 1018 gives reference to ASTM D1412 as a method of determining the moisture-holding capacity of hard coals.
Who is ISO 1018-Determination of moisture-holding capacity of hard coal for?
ISO 1018 on determination of moisture-holding capacity of hard coal applies to:
- Coal mining plants
- Coal electricity generation plants
- Coal refining plants
- Importers and suppliers of coal
Why should you use ISO 1018-Determination of moisture-holding capacity of hard coal?
The moisture-holding capacity shows the rank of hard coals and is used in coal classification for correcting the calorific value of the sample to the moist mineral matter-free basis. The full moisture-holding capacity is that of the coal in equilibrium with an atmosphere saturated with water vapour. Since there are impossible to overcome experimental difficulties in working with such an atmosphere, the determination is carried out at 96 % to 97 % relative humidity.
ISO 1018 provides you guidance on test method that applies to wetted an unwetted coal which allows you to perform the method correctly and according to your specific purposes.
Guidance in ISO 1018 allows you to determine the moisture holding capacity of hard coal which enables you to classify coal based on the relative efficiency of heating during combustion.
