Significance and Use
5.1 This test method is intended for determination of bulk loose or tapped density or both for plutonium oxide or similar metallic 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 Values of loose bulk density obtained using this test method should be used with caution since they can vary considerably depending on 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 other factors.
5.4 This test method may be useful for the determination of the Carr Compressibility Index as described in Test Method D6393.
1.2 This test method is applicable when limited quantities of powder are available for performance of the measurements. Alternative test methods, such as Test Methods B527 or D7481, may be used when sufficient quantities are available.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. Some specific hazards statements are given in Section 7 on Hazards.
