This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. While reporting density is not regarded as nonconformance with this standard, unit weights should asttm calculated and reported since the results may be used to determine force or stress.

Active view current version of standard. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. 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 both. However, balances or scales measure zstm and weight must be calculated.

In addition, there are published data to indicate that these test methods have a high asmt of variability. In this system, the pound lbf represents a unit of force weight.

However, balances or scales d4523 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. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. See Section 3 for descriptions of terms. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

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.

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single 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.

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

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. D2453 of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. Density is mass per unit volume whereas unit weight is force per unit volume.

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. In this system, the pound lbf represents a unit of force weight.
