ASTM D2974-20 covers the measurement of water (moisture) content, ash content, and organic material in peats and other organic soils, such as organic clays, silts, and mucks.
Method A—A peat or organic soil sample is reduced by quartering to obtain a 50.00 +10 g test specimen. A water content determination is made by drying the test specimen in a l10°C±5° C oven. The loss of mass due to drying is considered to be water. After oven drying, the test specimen is placed in a furnace that is then gradually brought up to a temperature of 440+10%.The specimen remains in the furnace until it is completely ashed. Then it is removed and placed in a desiccator to cool to room temperature before determining its mass. The substance remaining after ignition is the ash. The water content, ash content and amount of organic material is then calculated. This method is used for general purposes/classification of peats and organic soils and must notbe used for peat or organic soil being used or evaluated for useas a fuel.
