ASTM D2974-14 Historical

1.1.1 Test Method A-Moisture is determined by drying peat or organic sample at 110 ± 5°C.

1.1.2 Test Method B-Alternative moisture method which removes the total moisture in two steps: (1) evaporation of moisture at room temperature, (2) subsequent oven drying of air dried sample at 110 ± 5°C. This method is used when the peat is to be used as fuel.

1.1.3 Test Method C-Ash content of a peat or organic soil sample, for general purposes, is determined by igniting oven dried sample from moisture content determination in a furnace at 440 ± 40°C.

1.1.4 Test Method D-Ash content of a peat or organic soil sample, for materials used for fuel, is determined by igniting oven dried sample from moisture content determination in a furnace at 750 ± 38°C.

1.4.1 The procedures used to specify how data are collected/recorded or calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user's objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyone the scope of this standard to consider significant digits used in analysis methods for engineering design.
