In this system, the pound lbf represents a unit of force weight. 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.

Therefore, considerable engineering judgment must be used in relating the engineering properties of soil to the state of compactness. The astk “dry before density or unit weight is omitted in the title and remaining portions of this standard to be consistent with the applicable definition given in Section 3 on Terminology. In this standard density is given only in SI units. In the inch-pound system, it is common to assume that 1 lbf is equal to 1 lbm.

In addition, there are published data to indicate that these test methods have a high degree of variability. This standard 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 equal to 1 lbm.

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

Historical Version s – view previous versions of standard. This standard has been written using the gravitational system of units when dealing with the inch-pound system. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. 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

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. In this system, the pound lbf represents a unit of force weight. Therefore, test apparatus dimensions and sstm given in inch-pound units are regarded as the standard.

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard.

## ASTM D4253

Density is mass per unit volume whereas unit weight is force per unit volume. 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.

However, balances or scales measure mass; and weight must be calculated. Link to Active This link will always route to the current Active version of the standard.

Reliable results depend on many factors; Practice D provides a means of ast, some of those factors. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. In addition, they are representative of the significant digits that generally should be retained.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
