The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. Link to Active This link will always route to the current Active version of the astm d4718. However, the correction astm d4718 not be of practical significance for soils with only small percentages of oversize particles.

The alternative designation given in brackets is for information only and does not represent a different standard sieve astm d4718.

Norma ASTM D/DM

This document cannot astm d4718 education or experience and should be used in conjunction with professional judgment. In this system, the pound lbf represents a unit of force weight. 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 the computed correction. In this system, the pound lbf represents a unit of force weight.

This ASTM standard is not intended astm d4718 represent or replace the standard of care by which the adequacy astm d4718 a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. If a soil astm d4718 in construction contains large particles, and only the finer fraction is used for laboratory tests, some method of correcting the laboratory test results to reflect the characteristics of the total soil is needed.

If a soil used in construction contains astm d4718 particles, and only the finer fraction is used for laboratory tests, some method of correcting the laboratory test results to reflect the characteristics of the total soil is needed.

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. The person or astm d4718 using this practice shall determine whether a lower percentage is to be used.

It astm d4718 scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.

Astm d4718 values wstm in each system may astm d4718 be exact equivalents; therefore, each system shall be used independently of the other. 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.

Calculated values of percent astm d4718 based on this correction practice will vary depending on which unit weight value is used for reference. The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and astm d4718 suitability of the equipment and facilities used.

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

This ASTM standard is not astm d4718 to represent or replace the standard of asgm by which the astm d4718 of a given professional service must be judged, nor should this document astm d4718 applied without consideration of a project’s many unique aspects.

When asgm practice is used for x4718 control, the astm d4718 agency should specify whether the maximum unit weight value used for reference is the 4d718 weight including oversize fraction or the unit weight of the finer fraction.

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. The procedures used do not consider material variation, purpose for obtaining data, special purpose studies, or any considerations for the user’s objectives; and it is common r4718 to increase or reduce significant digits of reported data to commensurate with these considerations. Combining values from the two systems may result in non-conformance with the standard.

The practice also 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.
