Description of ASTM-D1997 2020ASTM D1997-20Active Standard: Standard Test Method for Laboratory Determination of the Fiber Content of Peat and Organic Soils by Dry MassASTM D1997Scope 1.1 This test method covers the laboratory determination of the fiber content of peat and organic soils by dry mass. Classification D4427 provides the methodology to classify peat as it is used in this standard. 1.2 Pieces of plant material such as roots or wood, larger than 20 mm in smallest dimension are not considered fibers. 1.3 Because this test method is simple and does not need sophisticated equipment in order to be performed, it is especially recommended for routine reconnaissance work where large numbers of samples need to be tested and mineral contents are low. 1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Alternate sieve designations in parentheses are as provided in Specification E11. 1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. 1.6 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. 1.7 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.
