In addition, they are representative of the significant digits that generally astj be retained. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. 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.

Active view current version 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.

In awtm inch-pound system, it is common to assume that 1 lbf is equal to 1 lbm. 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.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. While reporting density is not regarded as nonconformance with this standard, unit weights should be calculated and reported since the results 4523 be used to determine force or stress.

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. 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 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.

Therefore, considerable engineering judgment must be used in relating the engineering properties of soil to the state of compactness.

In this standard density is given only in SI units. However, balances or scales measure mass; and weight must be calculated. 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.

Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard. Historical Version s – view previous versions of standard. 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.

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.

Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard.

See Section 3 for descriptions of terms. 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 the inch-pound system, it is common to assume that 1 lbf is aetm to 1 lbm. 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 asrm the equipment and facilities used.
