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. This standard is also available to be included in Standards Subscriptions. Performance of the test method utilizing another system of units shall not be considered non-conformance. Users of this test method are cautioned that compliance with Practice D v4959 not in itself ensure reliable results.
A correction factor is valid when the difference is consistent for several comparisons, and is reconfirmed on a regular specified basis. Subscription pricing is determined by: Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.
This is important if the water content will be used to calculate other relationships awtm as moist mass to dry mass or vice versa, wet unit d495 to dry unit weight or vice versa, and total density to dry density or vice versa.
