1.1 This test method covers the laboratory determination of the fiber content of peat (as defined in Classification D4427) by dry mass. It also may be used for non-peat organic soil materials.

1.2 Because this test method is simple and requires no sophisticated equipment to perform, it is especially recommended for routine reconnaissance work, where large numbers of samples need to be tested and mineral contents are low.

1.3 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. Use Practice D6026 for determining significant digits to report.

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.
