New ASTM Advanced Ceramics Standard to Help with Nuclear Power
The new standard (C1863) was developed by the ASTM International committee on advanced ceramics (C28) and complements another ASTM International standard for hoop tensile strength, C1819.
ASTM International recently announced a new test method that could reportedly play an important role in supporting next-generation nuclear power through the advanced ceramics that are used to make many parts of nuclear reactors. According to ASTM International member Michael Jenkins, the new standard harmonizes many test methods developed over the years to measure the stress-strain behavior and strength of composite tubes subjected to internal pressure.
Using the standard, “engineers can measure the strength of tubular components made of ceramic composites and subjected to internal pressure so as to create safe designs that avoid failure,” said Jenkins, president and chief engineer at Bothell Engineering and Science Technologies.
The new standard (C1863) was developed by the ASTM International committee on advanced ceramics (C28) and complements another ASTM International standard for hoop tensile strength, C1819. Specifically, C1863 describes what is often called a tube burst test that is applicable to tube geometries.
This test determines the hoop tensile strength, including stress-strain response of continuous fiber-reinforced advanced ceramic tubes subjected to an internal pressure direct pressurization undergoing monotonic uniaxial loading at ambient temperature. According to Jenkins, test and design engineers working to obtain U.S. Nuclear Regulatory Commission certification using the American Society of Mechanical Engineers Boiler and Pressure Vessel Code for new designs in nuclear applications will find the new standard useful.
