| 1. Scope | ||
|
1.1?This test method covers the determination of the fracture toughness of cemented carbides (KIcSR) by testing slotted short rod or short bar specimens. 1.2?The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.3?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. 1.4?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. |
