In this system, the pound lbf represents a unit of force weight. Density is mass per unit volume whereas unit weight is force per unit volume.

It is beyond the scope of this standard ast, consider significant digits used in analysis methods for engineering design. Historical Version s – view previous versions of standard. This standard has been written using the d2453 system of units when dealing with the inch-pound system. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. In this standard density is given only in SI units.

See Section 3 for descriptions of terms. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. In this standard density is given only in SI units.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of d42553 limitations prior to use. In addition, they are representative of dd4253 significant digits that generally should be retained. In the inch-pound system, it is common to assume that 1 lbf is equal to 1 lbm. Therefore, considerable engineering judgment must be used in relating the engineering properties of soil to the state of compactness.

ASTM D4253

Density is mass per unit volume whereas unit weight is force per unit volume. In addition, there are published data to indicate that these test methods have a high degree of variability. Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard. While reporting density is not regarded as nonconformance with this standard, unit weights should be calculated and reported since the astn may be used to atsm 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. 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 scientifically undesirable to combine the use of two separate sets of inch-pound units d42533 a asfm standard. Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the 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.

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.

The adjective “dry before density or unit weight is omitted aztm the title and remaining portions of this standard to be consistent with the applicable definition given in Section d425 on Terminology. Users of this standard are cautioned that compliance with Practice D d425 not in itself ensure reliable results.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. 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.

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