Значение и использование

The purpose of this classification is to standardize the naming of peat materials so that the peat-producer can better identify the product and the peat-consumer better select peat materials to meet requirements. This system may also be used for peat resource evaluations, environmental impact reports, and preliminary engineering studies. The parameters selected for use in this classification are ones which have been determined to relate to the agricultural/horticultural, geotechnical, and energy uses of peats.

Note 1—The quality of the results produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D 3740 are generally considered capable of competent and objective testing/sampling/inspection/and the like. Users of this standard are cautioned that compliance with Practice D 3740 does not in itself assure reliable testing. Reliable testing depends on many factors; Practice D 3740 provides a means of evaluating some of those factors.
