This Estonian standard describes two- and single-stage methods for the determination of total moisture of oil shale, a method for the determination of moisture in an analysis sample, and the procedure for preparing the samples. The standard is valid for oil shale irrespective of the location of the deposit of origin.
Based on the standard, moisture is determined in a sample of trade oil shale as well as in samples taken for geological and technological research from layers, cores, tailings and other oil shale samples taken and prepared in accordance with a valid standard.
