Standard Test Method for Sand Equivalent Value of Soils and Fine Aggregate

Importancia y uso:

5.1 This test method assigns an empirical value to the relative amount, fineness, and character of clay-like material present in the test specimen.

5.2 A minimum sand equivalent value may be specified to limit the permissible quantity of clay-like or clay-size fines in an aggregate.

5.3 This test method provides a rapid field method for determining changes in the quality of aggregates during production or placement.

Note 3: The quality of the results produced by this standard are dependent upon the competence of the personnel performing the procedure and the capability, calibration, and the maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or similar acceptable guideline provides a means of evaluating and controlling some of those factors.
