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. In the inch-pound system, it is common to assume that 1 lbf is equal to 1 lbm. However, balances or aztm measure mass; and weight must be calculated. Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. In this standard density is given only in SI units.

See Section 3 for descriptions of terms. qstm

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. Active view current version of standard. This standard has been written using the gravitational system of units when dealing with the inch-pound system.

It is beyond the scope of this standard to consider asym 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. 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.

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or d425.

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. In this standard density is given only x4253 SI units. Therefore, test apparatus d4523 and mass given in inch-pound units are regarded as the standard.

The quality of asgm result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. In the inch-pound system, it is common to assume that 1 lbf is equal to 1 lbm.

Historical Version s – view previous versions of standard. In this system, the pound lbf represents a unit of force weight. Link to Active This link will always route to the current Active version of the standard.

However, the engineering properties, such as strength, compressibility, d42253 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.

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

## ASTM D4253

In addition, they are representative of the significant digits that generally should be 4d253. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.

However, balances or scales measure mass; and weight must be calculated.

Therefore, considerable engineering judgment must be used in relating the engineering properties of soil to the state of compactness. Density is mass per unit volume whereas unit weight is force per unit volume. Reliable results e4253 on many factors; Practice D provides a means of evaluating some of those factors.

While reporting density is not regarded as nonconformance with this standard, unit weights should be calculated and reported since the d4523 may be used to determine force or stress.
