The alternative designation given in brackets is for information only and does not represent a different standard sieve size. The word astm d4718 in the title dd4718 this document means only that the document has been approved through the ASTM consensus process.

Not all aspects of this practice may be applicable in all circumstances. The alternative designation given in brackets is for information only and does not represent a different standard sieve size. In this system, the pound lbf represents a unit of force weight. The astm d4718 stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. It is scientifically undesirable to combine the use of two separate d4781 of inch-pound units within a single standard.

It is astm d4718 undesirable to combine the use of two separate sets of inch-pound units within a single standard. Referenced Documents purchase separately Asym astm d4718 listed astm d4718 are referenced within the subject standard astm d4718 are not provided as part of the standard. The practice also is considered valid when the oversize fraction is that portion retained on some other sieve, but the limiting aatm of d718 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.

In this system, the pound lbf f4718 a unit of force weight. This practice provides a mathematical equation for correcting the unit weight and astm d4718 content of the finer fraction of a soil, tested to determine the unit weight and water content of the total soil.

The person or agency using this asgm shall determine whether a lower percentage is to be used. Users of this standard are cautioned that compliance with Astm d4718 D does not in itself ensure reliable results.

If a soil contains cobbles or gravel, or both, astm d4718 options may be selected which result in particles retained on astm d4718 specific sieve being discarded for example the 4. This method is recommended for use with materials Related Suppliers Searching for related suppliers If a soil used in construction contains large particles, and only the finer fraction is used for laboratory tests, some method of correcting the laboratory test results astm d4718 reflect the characteristics of the total soil is needed.

In addition, they are representative of the significant digits that generally should be retained. Calculated values of percent compaction based astm d4718 this correction practice will vary depending on which unit weight value is used for reference.

Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. Sieve size is identified by its standard designation in Specification E Notes are optional and private. Sieve size is identified by its standard designation in Specification E Calculated values of percent compaction based astm d4718 this correction practice will vary depending on which unit weight value is used astm d4718 reference.

Astm d4718 alternative designation given in brackets is for information only and does not represent a different standard astm d4718 size. This document cannot replace education or experience and should be used in conjunction with astm d4718 judgment.

The person or agency using this practice shall determine whether a lower percentage is to be used. Calculated values of percent compaction based on this correction practice will vary depending on which unit weight value is used for reference. The person or agency specifying this practice shall specify a minimum percentage of oversize particles below which the practice need not be applied.

This standard has been written using the gravitational system of units when dealing with the inch-pound system. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. 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 astm d4718 the computed correction.

This ASTM standard is not intended to represent astm d4718 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.

Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. The quality of the result produced by astm d4718 astk is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities astm d4718.

Norma ASTM D/DM

The quality of the result produced astm d4718 this standard is dependent on the competence of the personnel performing it, asym the suitability of the equipment and facilities used. The procedures used do not consider material variation, purpose for obtaining astm d4718, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to commensurate with these considerations.

The unit weight-water content relations determined by the tests reflect the characteristics of d47718 actual material tested, and not the astm d4718 of the astm d4718 soil material from which the test specimen was obtained.

Other MTBE grades may be available for blending that are not covered by this specification. The person or agency using this practice shall determine whether aastm lower percentage is to be used. However, the correction may not be of practical significance for soils with only small percentages of oversize particles.
