ASTM E821-16(2023)

Annotation of standard text ASTM E821-16(2023) :

This practice covers the measurement of the mechanical properties of materials during charged-particle irradiation, with the test materials designed to simulate or provide understanding of, or both, the mechanical behavior of materials when exposed to neutron irradiation. This practice includes requirements for test material and particle beam characterization (such as for strain, load, temperature monitoring and control, and specimen environment monitoring), and recommended procedures for measuring mechanical properties and for calculating radiation damage (such as particle ranges, damage energy, damage rates, and damage gradients). Methods for comparing ion damage with neutron damage are also recommended.
