It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational 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. Join your peers on the Internet’s largest technical engineering professional community.

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. However, balances or scales measure mass; and weight must be calculated. Students Click Here Join Us! After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.

In addition, they are representative atm 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. Density is mass per unit volume, whereas unit weight is force per unit volume.
