Density is mass per unit volume, whereas unit weight is force per unit volume. Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard. The adjective “dry” before density or unit weight is omitted in the title and remaining portions of this standards to be consistent with the applicable definitions given in Sections 3 on Terminology.

ASTM D4254 – 16

In this system the pound lbf represents a unit of force weight. However, astmm or scales measure mass; and weight must be calculated. 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.

D is often used for fine grained soils clayey sands, silts, etc. In the inch-pound system, it is common to assume that 1 lbf is equal to 1 lbm.

They determine relative density, which can be good for SPT correlation.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. In addition, there are published data to indicate that these test methods have a high degree of variability.

In this standard, density is given only in SI units. Methods B and C are provided for guidance of testing used in conjunction with special studies, especially where there is not enough material available to use a 0.

Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. In addition, they are representative of the significant digits that generally should be retained.

This test method has been written using the gravitational system of units when dealing with the inch-pound system. In the inch-pound system, it is common to assume that 1 lbf is ashm to 1 lbm.

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