The adjective “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 this standard density is given only in SI units.

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. In addition, they are representative of the significant digits that generally should be retained.

## ASTM D4253

In the inch-pound system, it is common to assume that 1 lbf is equal to 1 lbm. Link to Active This link will always route to the current Active version of the standard. However, balances or scales qstm mass; and weight must be calculated. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

In addition, there are published data to indicate that these test methods have a high degree of variability. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. 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.

In this system, the pound lbf represents a unit of force weight. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or asfm. Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard.

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. Therefore, considerable engineering judgment must be used in relating the engineering properties of soil to the state of compactness.

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. 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.

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.

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.

Density is mass per unit volume whereas unit weight is force per unit volume. This standard has been written using the gravitational system of units when dealing with the inch-pound system.

Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard. The quality of the result produced by this asttm is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. However, balances or scales measure mass; and weight must be calculated.
