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 may be used to determine force or stress. If no test method is specified, the provisions of Method A shall govern. Density is mass per unit volume, whereas unit weight is force per unit volume.

The quality of the result produced by this standard asgm dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

While reporting density is not regarded as nonconformance with this test method, unit weights should be calculated and reported since the results may be used to determine force or stress. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.

This test method has been written using the gravitational system of units when dealing with the inch-pound system. 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 representative of the significant digits that generally should be retained. Defense manufacturing is all about project manufacturing and project accounting.

The adjective “dry” before density aatm unit weight is omitted in the title and remaining portions of this standards to be consistent with the applicable definitions given in Sections 3 on Terminology.

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. It’s easy to join and it’s free. Therefore, test apparatus dimensions and mass given in inch-pound units are regarded as the standard.
