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

As the voice of the U. Agencies which meet the criteria of Practice D are generally considered capable of competent and objective testing. The procedures, axtm, and requirements necessary for selecting locations for obtaining intact samples, suitable for laboratory testing or otherwise determining engineering properties, is beyond the scope of this test method.

The values in parentheses are provided for information purposes only. Users of this method are cautioned that compliance with Practice D does not in itself assure reliable testing. This implicitly d22937 two separate systems of units; that is, the absolute system and the gravitational system.

Soil testing Lab Services: 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. In this system the pound lbf represents a unit of force weight. The precision of this test method is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used.

Atm use of this test method in soils containing an appreciable amount of particles larger than 4.

The use of this test method in soils containing particles coarser than 4. 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. When sampling or in-place density is required at depth, Test Method D should be used. This test method may not be applicable for soft, organic, highly plastic, noncohesive, saturated or other soils which are easily deformed, aztm during sampling, or which may not be retained in the drive cylinder sampler.

The test method involves obtaining a relatively undisturbed soil sample by driving asm thin-walled cylinder and the subsequent activities for the determination of in-place density.

The precision of this test r2937 is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. The inch-pound units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The procedures, precautions, and requirements necessary for selecting locations for obtaining intact samples, suitable for laboratory testing or otherwise determining engineering properties, is beyond the scope of this test method. When sampling or in-place density is required at depth, Test Method D should be used.

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.
