Active view current version of atsm. Reliable results depend on many factors; Practice D provides a means of r4253 some of those factors. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of 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 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.

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

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.

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

Density is mass per unit volume whereas unit weight is force per unit volume. 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.

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

Historical Version s – view previous versions of standard. D42553 this standard density is given only in SI units. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. This standard has been written using the gravitational system of units when dealing with the inch-pound system.

In addition, they are representative of the significant digits that generally should be retained. See Section 3 for descriptions of terms. In this system, the pound lbf represents a unit of force weight.

Users ast, this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard.
