    1.1 This test method describes procedures for determining the washability characteristics of coarse-coal fractions and fine-coal fractions. Each sample being tested can have more than one coarse-coal size fraction and more than one fine-coal size fraction (see Annex A1). Each such size fraction has an upper size limit and a lower size limit, neither of which overlaps with the next larger nor smaller size fraction.

    The specific gravity of each type of the coal ash showed similar values: those of FA1, BA1, and FA2 were 2.10, 1.96, and 2.07 (g/cm 3), respectively. Since specific gravity of fly ash is, typically, between 2.1 and 3.1 (g/cm 3), they are typical fly ash samples . Based on the chemical composition of the samples, Si and Al constituted more than half of BA1 and FA2.
