ASTM D2977-14

5.1 This practice separates peat material into arbitrary fractions based on particle size. Physical separation of peat material according to particle size provides a useful indicator of the properties of a peat specimen such as pore space, decomposition, etc. It provides a means of determining the amount of foreign matter not in a divided state such as sticks, stones, and glass.

1.1 This practice covers measurement of the mass percentage of fractions of a peat material defined in terms of selected ranges of screen sizes.

1.2 Units—The values stated in SI units are being regarded as standard. Units of inch-pound are provided for information only.

1.3 All measured and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.

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.
