In addition, they are representative of the significant digits that generally should be retained. Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. This standard is not included in any packages. The alternative designation given in brackets is for information only and does d471 represent a different standard sieve size. However, the correction may not be of practical significance for soils with only small percentages of oversize particles.

This document cannot replace education or experience and should be used in conjunction with professional judgment. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. However, the correction may not be of practical significance for soils with only small percentages of oversize particles. When this practice is used for construction control, the using agency should specify whether the maximum unit weight value used for reference is the unit weight including oversize fraction or the unit weight of the finer fraction.

ASTM D4718/D4718M – 15

Sieve size is identified by its standard designation in Specification E Nat all aspects of this practice may be applicable in all circumstances. The practice d47118 is considered valid when the oversize fraction is that portion retained on some other sieve, but the limiting percentage of oversize particles for which the correction is valid may be lower.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The person or agency specifying this practice ashm specify a minimum percentage of oversize d478 below which the practice need not be applied.

Your Alert Profile lists the documents that will be monitored. For some gradations, this interference may begin to occur at lower percentages of oversize particles, so the limiting percentage must be lower for these materials to avoid inaccuracies in axtm computed correction.

This standard has been written using the gravitational system of units when dealing with the inch-pound system.

The person or agency using this practice shall determine whether a lower percentage is to be used. The unit weight-water content relations determined by the tests reflect the characteristics of the actual material tested, and not the characteristics of the total soil material from which the test specimen was obtained.

This document cannot replace education zstm experience and should be used in conjunction with professional judgment. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Standards Subsctiption may be the perfect solution. The person or agency using this practice shall determine whether asgm lower percentage is to be used. If a soil contains cobbles or gravel, or both, test options may be selected which result in particles retained on a specific sieve being discarded for example the 4.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

Combining values from the two systems may result in non-conformance with the standard. E4718 practice provides a mathematical equation for correcting the unit weight and water content of the finer fraction of a soil, tested to determine the d7418 weight and water content of the total soil.

Calculated values of percent compaction based on this correction practice will vary depending on which unit weight value is used for reference.

In this system, the pound lbf represents a unit of force weight. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects.

The person or agency specifying this practice shall specify a minimum percentage of oversize particles below which the practice need not be applied. We have no amendments or corrections for this standard. As the voice of the U. The person or agency specifying this practice shall specify a minimum percentage of oversize particles below which the practice need not be applied. If a soil used in construction contains large particles, asrm only the finer fraction is used for laboratory tests, some method of correcting the laboratory test results to reflect c4718 characteristics of the total soil is needed.
