This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Density is mass per unit volume whereas unit weight is force per unit volume.

ASTM D4253

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. In this standard density is given only in SI units.

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. Density is mass per unit volume whereas unit weight is force per aatm volume. In the inch-pound system, it is common to assume that 1 lbf is equal to 1 lbm. However, the engineering properties, such as strength, compressibility, and permeability of a given soil, compacted by various methods to a given state of compactness can vary considerably.

ASTM D Standard

See Section 3 for descriptions of terms. However, balances or scales measure mass; and weight must be calculated. The adjective “dry before density or unit sstm is omitted in the title and remaining portions of this standard to be consistent with the applicable definition given in Section 3 on Terminology.

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. While reporting density is not regarded as nonconformance with this standard, unit weights should be calculated and reported since the results may be used to determine force or stress.

Astn, test apparatus dimensions and mass given in inch-pound units are regarded as the standard. This standard has been written using the gravitational system of units when dealing with the inch-pound system. However, balances or scales measure mass; and weight must be calculated.

Historical Version s – view previous versions of standard. Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard.

Therefore, considerable engineering judgment must be used in relating the engineering properties of soil to the state of compactness. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. In this system, the pound lbf represents a unit of force weight.

This standard has been written using the gravitational system of units when dealing with the inch-pound system. Users of this standard are cautioned that compliance with Aetm D does not in itself ensure reliable results. In addition, they are representative of the significant digits that generally should be retained. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. In this system, the pound lbf represents a unit of force weight.
