Description

ASTM B528-16-e1-Reapproved2020

Active Standard: Standard Test Method for Transverse Rupture Strength of Powder Metallurgy (PM) Specimens

ASTM B528

Scope

1.1 This test method covers determination of the transverse rupture strength of sintered, including post-treated, powder metallurgy test specimens by subjecting them to a uniformly increasing transverse force 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.

1.2 Limitations—The transverse rupture test is only applicable to relatively brittle materials. In cases where a ductile specimen is being tested and the permanent deflection as a result of testing exceeds 0.02 in. (0.5 mm), the test results may be questionable.

1.3 Test Method B406 should be consulted for determining the transverse rupture strength of cemented carbides.

1.4 The values stated 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.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This 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.
