1.1 These test methods cover the determination of the bulk density of both peat in its natural state and peat products (Note 1). These test methods consist of defining a volume of peat and determining the mass of that specific volume. The difference in the respective methods is in the procedures employed to determine the peat volume.
Note 1—Test Method D 2978 is used for specifying the volume represented by a quantity of loose processed peat or the volume of a peat bale.
1.2 Method A—This method, the core method, covers the determination of the bulk density of an undisturbed core of peat taken with a piston sampler or other suitable core sampler (Sections 6 and 7).
1.3 Method B—This method, the paraffin wax method, covers the determination of the bulk density of undisturbed clods or irregular pieces of wet peat and compressed peat products (Sections 8 and 9).
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
