The procedures used do not consider material variation, purpose for obtaining the data, 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 be commensurate with these considerations.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. Soils containing particles larger than 4. The test method involves obtaining an intact soil sample by driving a thin-walled cylinder into the soil and conducting specific measurements and calculations for the ashm of in-place density.

Standards Subsctiption may be the perfect solution. When sampling or in-place density is required at depth, Test Method D should be used.

The test method involves obtaining a relatively undisturbed soil sample by driving a thin-walled cylinder and the subsequent activities for the determination of in-place density. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering 2d937. In addition, they are representative of the significant digits that generally should be retained. Please first log in with a verified email before subscribing to alerts.

This implicitly combines two separate systems of units, that is, the absolute system and the gravitational system. It is scientifically undesirable d297 combine the use of two separate sets of inch-pound units within a single standard. The values given in parentheses after SI units are provided for information only and are not considered standard. The procedures used do not consider ashm variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to d29377 or reduce significant digits of reported data to be commensurate with these considerations.

When sampling or in-place density is required at depth, Test Method D should be used. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. Add to Alert PDF.

Agencies which meet the criteria of Practice D are generally considered capable of competent and objective testing. We have no amendments or corrections for this standard. This test may not be applicable with very hard natural soils or heavily compacted soils that may not be easily penetrated with the drive cylinder sampler.

When the in-place density is to be used as a basis for acceptance, the drive cylinder volumes must be as large as practical and not less than cm 3 0. The use asm this test method in soils containing an appreciable amount of particles larger than 4.

When the in-place density is to be used as a basis for acceptance, the drive cylinder volumes must be as large as practical and not less than cm 3 0. This test method may also be used to determine the in-place density of compacted soils used in construction of structural fill, highway embankments, or earth dams. The use of this test method in soils containing an appreciable amount of particles larger than 4. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.
