• Phạm vi áp dụng / Scope of standard: 1.1 This standard describes a method for measuring the density of powder metallurgy products that usually have surface-connected porosity. 1.2 The density of impermeable PM materials, those materials that do not gain mass when immersed in water, may be determined using Test Method B 311. 1.3 The current method is applicable to green compacts, sintered parts, and green and sintered test specimens. 1.4 With the exception of density values, for which the g/cm³ unit is the industry standard, the values stated in SI units are to be regarded as the standard. The values given in parentheses are converted in accordance with IEEE/ASTM SI 10 and are for information only. 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.
