1.1 This test method covers determination of the transverse rupture strength of sintered metal powder test specimens by subjecting them to a uniformly increasing transverse loading under controlled conditions. The term "transverse rupture strength," as used herein, defines the stress, calculated from the flexure formula, required to break a specimen as a simple beam supported near the ends and applying the force midway between the fixed line center of the supports. By varying the composition and preparation of specimens, actual production conditions can be closely simulated.
1.2 The following special tests should be consulted for the specified materials: Test Method
