Full Description

1.1This standard describes a method for measuring the density of powder metallurgy products that usually have surface-connected porosity.

1.2The density of impermeable PM materials, those materials that do not gain mass when immersed in water, may be determined using Test Method B311.

1.3The current method is applicable to green compacts, sintered parts, and green and sintered test specimens.

1.4With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimetre (g/cm) and gram (g) units is the long-standing industry practice, the values in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.5This 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.

1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
