ASTM D, Test equipment Controls

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. 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. Referenced Documents purchase separately The documents listed below are r4253 within the subject standard but are not provided as part of the standard.

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

In the inch-pound system, it is common to assume that ast, lbf d2453 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. 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.

However, the engineering atm, such as strength, compressibility, and permeability of a given soil, compacted by various methods to a given state of compactness can vary considerably.

In this system, the pound lbf represents a unit of force weight. Active view current version of standard.

In addition, there are published data to indicate that these test methods have a high degree of variability. In the inch-pound system, it is common to assume that 1 lbf asgm equal to 1 lbm. In this system, the pound lbf represents a unit of force weight.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. 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. However, balances or scales measure mass; and weight must be calculated.

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

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. Therefore, test 4d253 dimensions and mass given in inch-pound units are regarded as the standard.

In this standard density is given only in SI units. Therefore, considerable engineering judgment must be used in relating the engineering properties of soil to the state of compactness.

In addition, they are representative of the significant digits that generally should be retained. See Section 3 for descriptions asm terms.

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

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