ASTM B312 covers the standard test method for green strength of specimens compacted from metal powders. ASTM B312 is used to determine the transverse rupture strength of a material during a sintering process, prior to the bond being completely cured. The green strength is determined by the amount of force that is needed to break the unsintered test specimen.


ASTM B528 covers the test practices that are to be used for transverse rupture strength of sintered PM test specimens. The apparatus that is needed for this test is an analytical balance to determine the mass of the powder used in the test specimen and the test specimen. A PM tool set to sinter the test specimen. More details can be found in ASTM B925 on the official ASTM website.
