ASTM D4427-23 PDF

Scope: 1.1 This classification is a system for subdividing and assigning nomenclature to peat samples through laboratory tests. 1.2 Peat is considered to be a naturally occurring organic soil primarily derived from decomposing plant material that has sedentarily accumulated in water-saturated, anaerobic environments. It is found in peatlands, bogs, mangroves, mires, moors, and muskegs and is generally composed of mosses, grasses, leaves, sedges, and shrubs. Changes in depositional environment can create subsurface peat deposits underlying inorganic soils. Typically, peat has a low density, high water content, and is quite compressible when compared to other types of soil 1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
