ASTM D Standard

Active view current version of standard. 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 scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. Density is mass per unit volume whereas unit weight is force per unit volume.

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

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. In addition, they are representative of the significant digits that generally should be retained. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

ASTM D, Test equipment Controls

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or wstm. However, balances or scales measure mass; and weight must be calculated.

The adjective “dry before density or unit weight is omitted in the title and remaining portions of this astmm to be consistent with the applicable definition given in Section 3 on Terminology.

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 asrm soil to the state of compactness.

It is the responsibility of the user of atm standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Therefore, 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. 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 d44253 as the standard. In this system, the pound lbf represents a unit of force weight. Users of this standard are cautioned that compliance with Practice D d42533 not in itself ensure reliable results.

Historical Version s – view previous versions of standard. 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.

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.

In the inch-pound system, it x4253 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.

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.

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

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. 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 beyond the scope of this standard to consider 4d253 digits used in analysis methods for engineering design.
