Standard Test Method for Determination of Loose and Tapped Bulk Densities of Small Quantities of Plutonium Oxide

Importancia y uso:

5.1 This test method is intended for determination of loose or tapped bulk density or both for PuO₂ powders or compounds in the nuclear industry. It is intended for use when the quantity of available material for performing the measurements is limited because of reasons such as nuclear safety or laboratory scale limits on nuclear inventory.

5.2 This test method can be applied to other metal powders in the nuclear industry provided that appropriate validation has been performed.

5.3 Values of loose bulk density obtained using this test method should be used with caution since they can vary considerably depending on factors such as the initial state of dispersion of the test specimen, height-to-diameter ratio of the specimen in the graduated cylinder, the dryness of the powder, and operator-to-operator variation (for example, the speed with which the sample is poured into the cylinder).

5.4 The data from the tapped bulk density test can be used to estimate the needed volume of small containers holding a fixed mass of powder that has been compacted.

5.5 This test method may be useful for the determination of the Carr Compressibility Index as described in Test Method D6393.
