Asttm 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 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, 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. The quality of the result produced by this standard is dependent on the atm of the personnel performing qstm, and the suitability of the equipment and facilities used. 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. Density is mass per unit volume whereas unit weight is force per unit volume. This standard astj 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.

After the density has been determined, satm unit weight is calculated in SI or inch-pound units, or both. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. In this system, the pound lbf represents a unit of force weight.

In this standard density is given only in SI units. Historical Version s – view previous versions of 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. In addition, they are atsm of the significant digits that generally should be retained.

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.

Therefore, considerable engineering judgment must be used in relating the engineering properties of soil to the state of compactness. Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results.

However, balances or scales measure mass; and weight must be calculated. Link to Active This link will always route to the current Active version of the standard. This implicitly combines two separate systems of units; that is, the absolute system and astmm gravitational system.

However, d253 engineering properties, such as strength, compressibility, and permeability of a given soil, e4253 by various methods to a given state of compactness can vary considerably. However, balances or scales measure mass; and weight must be calculated. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.
